You love it when your house is nice and cool even when the sun is on its full glory outside, increasing the temperature ominously. Needless to say, this is precisely the time when your AC decides to act up and shuts now. Now your peaceful world comes to an end. Before you panic, allow us to soothe your fraying nerves because most often than not, it is a case of the blown fuse. Now that you know it is nothing big, the question that comes to mind is – “How to tell if AC fuse is blown?”
Before we answer this question, let us take a few minutes to understand the fuse. This knowledge is critical to comprehend the reason behind a blown fuse. Once the reason is known, you can contain the problem.
The AC Fuse
During the hot summer months, when the sun is at its peak, your AC works hard to maintain the pleasantly cool atmosphere inside the home. Sometimes the continuous hours of operation with no respite in-between heats the unit beyond an acceptable level. When this happens, the circuit breaker trips or the fuse blows to prevent any lasting damage to your AC. In short, a blown fuse is just a precautionary measure to protect the machinery.
A fuse is sensitive to heat. Whenever there is a power surge or the unit heats excessively the filament in the fuse melts. This occurrence is the blown fuse. The fuse is designed in such a manner that it can bear the load of fixed amperes only. If the voltage increases beyond its amperage capacity, the fuse blows. Essentially, when the fuse blows, it cuts the power supply to the unit and thereby saving the unit from any further damage.
How To Tell If AC Fuse Is Blown
If you suspect that your AC may have blown a fuse, the first thing you shall notice is that the outside unit of your AC is not doing anything. You may hear a minor humming sound, but that is the extent of it. The humming sound is produced because, despite no power, the furnace keeps asking the AC to run.
Can I Check For A Blown Fuse?
If you understand the basic electrical system of the AC, you can indeed check for a blown fuse yourself. However, not all of us have that knowledge, and yet we try to decipher the problem on our own. This can be quite dangerous. Until and unless you are sure about what you are doing and you have taken the necessary precautions to ensure your safety, you should not try and take remedial actions to correct the problem. Most often, the current is still passing through the wires, which can give you a strong jolt or shock. So refrain from being too adventurous. Contact your local HVAC company to come and inspect your air conditioner.
Checking For Blown Fuse With Voltmeter
The best way to test for a blown fuse is by using a voltmeter.
1. To verify that you have a blown fuse on hand, the first step is to locate the disconnect box. It is usually grey in color and mounted near the outdoor AC unit.
2. Lift or swing open the outer and inner cover of the disconnect box to expose the cables. Locate both the incoming (line) and outgoing (load) wires. Remember both of them carry 110 volts, so be cautious.
3. Check the voltmeter to make sure that it is functioning properly. It should display a reading of zero volts or infinity depending on the model you are using.
4. Attach the voltmeters leads to the lugs joining the two line wires. The voltmeter should read somewhere between 220-240 volts. This means power is coming as far as the fuses. If the voltmeter does not read anything on this side, the problem isn’t the fuses.
5. After testing the incoming wires, it’s time to test the outgoing wires. Join the voltmeter’s leads to the lugs of the load wire. If you get a zero-volt reading, you have a blown fuse. Else, the problem is in another place.
What If You Don’t Have A Voltmeter?
Not everyone has a voltmeter at home. If you don’t have one, the world does not come to an end. You can still check whether your AC has blown a fuse or not. Check the volt capacity of the fuse in the disconnect box. Buy new fuse of the same capacity. Replace the old fuse with the new one and check whether the AC works. If yes, you had indeed blown a fuse. If no, you now have an extra set of fuses on hand. The good thing is that they can be used later when your AC indeed does blow a fuse. Baad thing is that you still have a non-functioning AC on hand.
A Few Tips
1. If you want to check for a blown fuse yourself, make sure that your hands and feet are dry. Also, see to it that so is the floor.
2. If you are not an electrician, take a pic of the disconnect box when you open it so that you bring it back to the status quo while closing it. Pictures are especially useful when you are replacing the fuse. You can verify the exact manner in which they should be placed.
3. If your AC keeps on blowing a fuse, it means there is another problem that needs to be addressed first.
4. Your local HVAC technician is the best person to inspect your AC for any troubles.
By now, the above information has given you a fair idea of how to tell if AC fuse is blown. Even if you cannot do the necessary job yourself, you at least have a good idea of what the AC technician will do. Armed with this knowledge, nobody can try and fool you. It is always better to have some knowledge rather than being completely ignorant.
It’s quite aggravating when your air conditioner keeps blowing fuse in circuit board. If it’s just a one-time thing, you may not think much about it. But, if it happens quite frequently, you have a problem on hand. Electrical problems can be overwhelming, especially when you don’t know why they are happening and what to do. So, in our bid to make you more knowledgeable in this context, we shall explain a bit more about the fuse, why your AC keeps blowing it, and what is the most probable solution – armed with this information you can take quick and competent decisions in regards to your AC.
What Is A Fuse And How Does It Work?
A fuse is an electrical safety device which is made of metal filament or wire. It is usually in a cover or casing. The purpose of a fuse is to provide safety to the electrical device from overload or high voltage. The fuse is in the disconnect box or the trip box, connected to your AC.
While your AC is working, if there is a power surge or a short circuit, the filament in the fuse melts. This stops the flow of electricity and thus acts as a circuit breaker. Often this occurrence is also referred to as a blown fuse.
On its own, the fuse cannot be a problem because it is just a part of the safety mechanism. Fuses are very sensitive to overload, and so they overheat extremely fast. Consequently, if the fuse has blown, it means you have a problem on hand for which you may require professional assistance.
Why Air conditioner Keeps Blowing Fuse In Circuit Board?
There could be several reasons why air conditioner keeps blowing fuse in circuit board. The most probable of these are –
1. Loose Electrical Cables – There could be loose electrical cables inside the circuit box or somewhere in your AC which could be causing a short circuit. Only a thorough check by a trained technician will reveal where these loose wires are. Once they are discovered, you will just have to tighten them so that they do not cause repeated short-circuiting, which results in a blown fuse.
2. A Faulty Capacitor – The work of a capacitor is to regulate the flow of electricity inside the AC. When the capacitor develops a fault, it is unable to work properly. This can cause the fuse to blow repetitively. To solve this problem, the capacitor will have to be replaced. Sometimes an old or blocked motor will force the capacitor to work over-time. This puts a lot of strain on the capacitor, which in turn can continuously blow the fuse. The perfect solution for this problem is to get the motor checked and take action as advised by the HVAC technician.
3. Problem In Condenser – Dirty coils on your ACs or HVACs condenser can also cause strain on the capacitor, making it run overtime. Consequently, the fuse may blow. Similarly, if the condenser fan has to work harder to cool your home, it may cause electrical problems, one of which is a fuse blowing often. The solution lies in getting regular maintenance of your AC done so that these issues can be found at the very beginning and addressed ASAP before they turn into before troubles.
4. Low Refrigerant Level – When the air conditioner is low on refrigerant, the unit must work harder to cool the home. The extra work which the AC has to perform can trip your circuit breaker or result in a blown fuse. If the refrigerant level is not topped to adequate, the blowing of fuse becomes a regular occurrence. As is clear from the discussion, the solution lies in maintaining an optimum refrigerant level in the AC. A technician can come and check the refrigerant level in your AC and also, if they recommend replacing the coils that carry the refrigerant, pay heed to their advice and take quick action.
5. Dirty Air Filters – Anything that puts continuous pressure on the AC will subsequently result in a blown fuse. For that matter, it can be something as inconsequential as a dirty air filter. Especially on hot sunny days when the AC works overtime, hours of operation under tremendous strain can take its toll in the form of a blown fuse in the circuit board. Replace the air filters every month in summers to prevent this from happening occasionally.
6. Small Fuse – Somewhere down the line, someone replaced the fuse in the AC circuit board with a smaller capacity one which was inadequate to bear the load of your AC. Whenever the fuse blows, you replace with the fuse with a similar capacity one without realizing the folly of this action. Consult an HVAC technician about this and replace the fuse with one that has an adequate load-bearing capacity. Once done, this should solve the problem.
As you can concur, most times it is small things which cause big problems. These small factors can be addressed well in time through periodic maintenance of the AC by a professionally trained technician. Time and again, we have stressed upon the benefits of maintenance for the longevity of your AC. However, this does not mean that no further problems will arise ever again. Problems will arise due to basic wear and tear and also due to things not in your control. At such times, the best you can do is be attentive towards even the smallest untoward sound that your AC makes.
When it comes to an air conditioner that keeps blowing a fuse in the circuit board, it is necessary that you let a trained technician check it out. A thorough inspection of your system, by them, will bring to light any additional issues that might be compounding the problem.

You pass by the thermostat umpteen times a day without sparing it a second glance. It is that small screen in your house, mounted on the wall, where you set the desired temperature. The day the cooling or heating does not match your expectations is the day when you stop to glance and fiddle with it. Like every other working part, it too is vulnerable to developing faults. Have you ever wondered why your thermostat goes blank then comes back on? This is an indication of some part in the thermostat not working as it should.
A thermostat is a crucial component of every AC and HVAC unit. It senses the temperature and helps regulate it at the defined level. A thermostat works like a switch. It is usually heat activated. A part of the thermostat is the temperature sensor. It causes the switch to open or close, completing or interjecting an electrical circuit which runs the heating and cooling system of the home.
Diagnosing The Issue
The thermostat goes blank then comes back on; this is a classic symptom of short cycling. This is a problem that usually originates within the heating system. On average, an air conditioning cycle lasts around 20 minutes. At times, the number of cycles increases. This issue is known as “short cycling.” Short cycling is a term that refers to the condition where the AC turns on and off in small bursts. When this happens, the house neither heats nor cools effectively. To the naked eye, short cycling is visible as the thermostat going blank then coming back on repeatedly in quick succession.
Main Causes Of Thermostat Going On And Off
A few reasons why your thermostat goes blank then comes back on are –
1. Improper Location Of Thermostat – Your AC or HVAC thermostat consists of a temperature sensor which registers the surrounding temperature. Based on this reading, it sends the “on” and “off” signals to the compressor of the unit. Ideally, the thermostat should not be installed near a window which receives a lot of sunlight. Neither should it be installed anywhere near a supply air vent. These places will confuse the thermostat about the actual temperature inside your home.
2. Faulty Thermostat – For all you may know, the thermostat itself could have developed a fault which is causing short cycling. It could be as simple as a loose wire or something more severe, which may need replacement. The best person to validate this is your local HVAC technician. A faulty thermostat is not a major issue, replacing it will bring an end to the repeated switching on and off of the thermostat.
3. Refrigerant Leak – Refrigerant leaks occur due to corrosion and wear and tear of the coils. If your AC also has a refrigerant leak, it means that the level of Freon in your unit may be low. The coolant or refrigerant is vital for absorbing heat from the air and cooling it. So, when it is on the low side, the pressure level in the compressor becomes uneven, causing it to turn on and off intermittently. In turn, the thermostat also goes on and off repeatedly. If left unattended, this problem can cause serious damage to your unit. If you see any signs of a refrigerant leak, attend to it straight away.
4. Dirty Air Filters – Your AC may have a dirty or clogged air filter causing airflow restrictions. When the airflow is restricted, the evaporator coil becomes frozen, which causes the unit to turn on and off. As mention above also, this causes the thermostat to go blank and come back on again. Air filters should be cleaned and if necessary, replaced at least once a month. You can do this more often if you stay in a place where dust is always present in the air and if you are constantly running your AC in the summer.
5. AC Too Big For Your Home – The HVAC system installed in your home may be too big for it. This may seem odd because it cools your home faster. But the fact is if an AC unit is big for a home, it cools the house quickly and shuts off shortly after turning on. At first glance, you may think it is a good thing, but unfortunately, it increases your electricity bill as well as the chances of a potential breakdown. Prior to installing a new AC unit, ask a skilled technician to do an assessment of which size of AC is best suited for your needs.
Other Possible Causes
Not all AC units have a thermostat that requires batteries, but some do. Weak batteries can cause the thermostat screen to go blank then come back on again. You need to first figure out if this is the case with your thermostat. If yes, remove the front panel of your thermostat and replace the batteries with fully charged new ones. The task is relatively easy to perform and can be easily accomplished by you.
The Next Step
Now that you know that short cycling involves the compressor, we recommend that you immediately contact your local HVAC company to come and access the problem. If left unattended for a long time, this can evolve into a much bigger and expensive issue.

When your AC is not working as it should, your mind runs through all possible scenarios. You need a quick answer to your questions and a prompt solution to go with them. Many times when the AC malfunctions, the problem is very small, as small as a faulty capacitor. But how are you to deduce what is wrong with your AC? You are in good hands, for today we will tell you all you need to know about a bad capacitor. Moreover, this post will also enhance your knowledge on how to tell if capacitor is bad on AC unit.
Let’s Begin With The Basics…
1. What Is A Capacitor – A capacitor is a device which is used to store an electric charge. It consists of one or more pairs of conductors. These conductors are separated by an insulator.
2. What Does A Capacitor In AC Look like – The AC capacitor looks like a tall and shiny cylinder with wire connectors leading to it.
3. Function Of Capacitor In AC – An AC capacitor is also known as a “Run Capacitor”. Its function is to direct energy to the motor that powers the air conditioning unit. The capacitor in the AC provides the starting boost that is needed to turn it on and also gives constant power for it to keep running. It achieves this task by initializing a phase difference amid two windings that are inside the motor. This generates an initial starting torque which helps to turn the rotor of the compressor motor.
4. How Long Do AC Capacitors Last – With great strides in technology, today’s AC capacitors can last as long as 20 years. Some factors, like undersized capacitor and heat exposure, can cause them to wear out and go bad much faster.
Signs Of A Bad Capacitor
How to tell if the capacitor is bad on AC unit? This is more a matter of ruling out the most obvious problems first. Start with the basic solutions first, like changing the air filters and cleaning the ducts. If one or more of the following symptom still persists, it is an indicator of a bad capacitor –
1. AC does not start immediately instead takes some time.
2. It does not blow cold air.
3. When it starts, you can hear a distinctive humming sound.
4. Your air conditioner shuts off without any reason.
5. The air conditioner fails to start at all.
Your AC taking a while to start and not starting at all are dead giveaways of a faulty capacitor. For the other symptoms, there could be some other reason as well. These could vary from a refrigerant leak to clogged ducts and filters. As already stated above, look for simple answers first.
What Does A Bad Capacitor Do To AC?
When the AC capacitor goes bad, it prevents the outdoor AC unit from functioning effectively. The possible scenarios include –
1. The fan may not spin
2. The compressor may not start.
3. The compressor may shudder and balk while starting
4. The compressor may shut off quickly.
5. A humming sound comes from the motor, and yet it does not start.
Any of these possible scenarios will put tremendous strain on the motor can cause the motor to burnout.
How To Tell AC Capacitor Is Bad
So your AC takes time to start, or maybe it’s not starting at all, these point to a defective capacitor. But how can you tell if the capacitor is really defective, for sure? Easy enough. Here’s what you need to do –
1. Check Condition Of Capacitor – The outer metallic shiny cover of the capacitor which protects the inside components should not bulge or have any cracks or leaks. If it has either of these, the capacitor is bad. In some extreme cases, you may even see smoke rising from it accompanied by a burning odor. Fluid oozing out from the base of the capacitor is also an indication of a bad capacitor.
2. Multimeter Check – Do this, if and only if, you know how to use a multimeter. First, switch off the power to the AC unit. Then apply leads to the capacitor so as to drain its stored energy. Now, connect one lead to the ground wire by touching it and with the other lead, turn by turn, touch all other wires. This will dispel the electrical charge held by the capacitor. You may then check capacitance across the terminals on the capacitor.
Capacitors can cause serious harm to a person if not handled correctly. Since they hold an electrical charge even when the unit is disconnected, they are capable of giving a strong electrical shock. It is thus necessary to first drain their energy. Once you are sure that the complete power has been dissipated from it, you can do further investigation. Since all of us are not electrically and technically oriented, it is strongly advised that you let a trained professional deal with such a problem. Your local AC technician or your local HVAC company are more than capable of handling these issues.
Choosing A Replacement Capacitor
If the AC capacitor is indeed faulty, you will have to replace it with a new one. But, you cannot just pick any capacitor as a replacement. The things that matter are not the brand, size, and shape of the capacitor. What truly matters is the voltage rating and the base unit of capacitance (microfarads). This information will be mentioned on the original capacitor. Take its pic so that you don’t forget and have the necessary information handy.

The HVAC system is the heart of your household. It is a machinery which consists of many big and small parts. In machinery as complex as that occurrence of a fault is normal. What is important is that you deal with them promptly and efficiently. The local HVAC company is your best answer. However, being a little proactive, you too should know a little about the things that could go wrong with your HVAC unit. If you have at least some basic knowledge, nobody would be able to fleece you easily. In our bid to educate you about the issues you could face in relation to your HVAC, today we shall deal with the transformer. The transformer of the HVAC unit is also susceptible to developing faults. But how can you be sure of that? This post will help you understand a bit more about transformers and also tell you about bad transformer symptoms in HVAC.
What Is A Transformer?
A transformer is a device which can increase or decrease the voltage of an alternating current or AC. It is a passive device which transfers electrical energy from one circuit to another. This is achieved through electromagnetic induction.
Role Of HVAC Transformers
Transformers are used when the incoming electricity voltage needs to be either raised or lowered to meet the requirements of the other electrical components or parts. The work of a transformer is to change the voltage that travels from the circuit board to the HVAC unit. This progression allows the air conditioner and the fan to work in synergy while cycling on and off. The usage of Electricity can be amplified or diminished depending on how much power is needed.
Where Is The Transformer Located?
In an HVAC unit, the transformer is located inside the furnace. But in a few cases, which is less than 10%, it can be found inside the AC unit situated outside.
Bad Transformer Symptoms In HVAC
There are a couple of things which are indicative of a bad HVAC transformer. These are –
1. Humming And Vibrating – The humming sound in transformers is normal. It is produced due to the expansion and contraction of the laminations or the iron core. However, if there is a drastic increase in this sound, accompanied by strong vibrations, it is indicative of a bad transformer in your HVAC unit. There could be other possible causes of the humming sound and the vibrations like incorrect installation or a faulty capacitor. So, it is best to let a technician come and check out where the real problem lays.
2. Tripped Circut Breaker – When the transformer of your HVAC unit goes bad, the circuit breaker will usually trip. It trips so that there is no surge of voltage. A voltage surge can fry various parts throughout the furnace and AC causing a major breakdown of the said equipment.
3. HVAC Not Working – With a bad transformer, your HVAC unit will not work even when it has an adequate power supply. This is a protective mechanism to save the unit from severe damage.
There is no sure-shot way of confirming that the HVAC unit is malfunctioning due to a fault in the transformer. This can only be discovered through the elimination method. The HVAC technician will start with the most probable and simple causes which could prevent the unit from functioning. When nothing else works, they will tackle the bigger causes, one of which being a bad transformer.
Checking The Transformer Is Bad
Your HVAC unit is not working, and you have worked your way through all possible causes. Nothing seems to solve the problem. It’s time to call in the reinforcements who can validate your findings and look for the real problem. The things you were attributing to a simple problem could actually be bad transformer symptoms in the HVAC unit. In order to confirm that the problem is indeed the transformer, you need to check it. For this, you need a multimeter, as well as the basic knowledge of using it. A faulty transformer gives an infinite or wide-open reading while a transformer without any fault reads between zero to 10 ohms which is indicative of a closed circuit.
Causes Of A Bad Transformer
Bad transformer symptoms in HVAC unit may appear due to the following reasons –
1. Bad Contactor – More often than not, it is a bad contactor which leads to a blown transformer. A bad contactor puts the entire unit under a lot of stress. When the tension or strain becomes too much for the unit to handle it mostly results in a blown transformer.
2. Wiring Issues – Loose wires or cables inside the transformer can cause a short circuit due to which the transformer may fry.
3. Power Surge – An electrical failure in the form of a power surge can also cause transformer failure.
Can I Replace The Transformer In My HVAC Unit?
If you are a trained technician who knows the ins and outs of a transformer, you can definitely do this job yourself. However, if you are not, you better think twice before taking on the job. Ask yourself whether it is worth paying a trained technician to do the job correctly? Or you are willing to foot the bill for a new HVAC unit if you make a hash of things? The answer will lead you in the right direction.
Time and again, electrical equipment malfunction. The good thing is that a malfunction does not mean you need to buy a new one. Today, you can simply replace the faulty or the bad component and your machine will be as good as new. HVAC units are no different. You can replace the part that has fried or melted, and once that is done, it will start functioning as normally as before. A few things to keep in mind are – take good care of your HVAC unit through regular maintenance and try to refrain from carrying out any repairs yourself.
If you are not careful, you may do more harm to the unit and maybe even get hurt or injured. There are people who are trained to care of such things, and they even have the necessary tools and replacement parts to complete the job quickly. Book an appointment with your local HVAC company if your unit is behaving abnormally. They are the most trusted people to take care of things immediately.
AC contactor problems are a common occurrence. But the headache they cause is major. When the contactor malfunctions, the AC does not work as it should. In summers, facing such a problem is both irritating and frustrating. If you want your AC to be in top working order, you should start getting its periodic maintenance done. Most issues can be caught during maintenance itself and do not evolve into something bigger. However, there may be exceptions. You have all possible troubleshooting and just realized that your AC contactor is not pulling in. The problem is identified, but why did it happen? Have you ever wondered if it could have been prevented?
Work Of Contactor In Air Conditioner
The contactor on the air conditioning unit is a switch that permits or stops power supply to the unit. It is a relay switch which directs electricity to the compressor of the air conditioner. When power is not needed, the contactor pulls the electrical contacts apart. It closes the contacts when something needs to be powered.
AC Contactor Not Pulling In – What Does It Mean?
Pulling in refers to the contactor closing the electrical contacts to power the air conditioner’s compressor. When the contactor does not “pull-in”, it means that the connections do not close to power the compressor. As a result, the AC works, but in the absence of a working compressor, it does not cool the home.
Why Is Your AC Contactor Not Pulling In?
AC contactor not pulling in is not a major issue. It can be taken care of without much botheration. Surprisingly, it is something that can be avoided through periodic maintenance. Usually, the contactor malfunctions due to corroded contacts, coil failure, and contactor burnout.
1. Corroded Contacts – The contact points in an AC contactor are susceptible to corrosion because of moisture present in the air. Also, if not cleaned regularly they tend to get covered with dust and other particle matter which gets sucked in with air. This makes the points of contact dirty due to which they do not work as they should leading to contactor failure.
Solution – The answer to this problem is “Contact Cleaner”. A little dab of contact cleaner will get rid of all that which is accumulated on the contact points. A very small amount of cleaner is required due to the small size of the contacts. Once cleaned, the contactor will start pulling in as needed.
2. Coil Failure – In addition to the contact points, a contactor also has coils. Sometimes these coils fail altogether. At such times, the contactor develops a fault, and it may reflect in the form of failure to pull in.
Solution – Again, the solution is not complicated. You can solve the problem by simply replacing the old contactor with a new one. Although it is possible to just replace the said coils, it is not a preferred method. This is because not only reaching the coils is hard, but so is finding the right size to replace them. Moreover, you can buy a new contactor relatively cheap, and its cost of replacement would also be low. As against this, replacing the coil is an intricate task, and so, its cost of replacement will nullify any financial benefit you foresee.
3. Contactor Burnout – When the voltage influx to the contactor is more than its load carrying capacity, it gets fried. Usually, during high voltage, the circuit breaker should trip. When that does not happen, the contactor suffers complete burnout. Even loose cables can cause a short circuit which could lead to the same result.
Solution – The solution to this problem is also contactor replacement. Although the process is simple, because of the sensitive nature of its function, the job is best completed by a trained HVAC technician.
Important Thing To Remember
Your AC contactor will have its important details like the type, model, and voltage either printed on the body or have a sticker with the same information. When you buy a new contactor, it is necessary to match all these details and replace it with an exact replica. Brand differences are acceptable; what is not acceptable is the voltage difference. Replacing with an undersized contactor will put your AC unit under strain. As a result, the AC will either develop some significant problem or the contactor will keep getting fried.
Also, remember whenever you are working with electrical equipment, it is necessary to first switch off the power supply to it. This step is necessary to ensure that you do not get an electrical shock by mistake. To avoid such scenarios, we always recommend using the services of trained personnel. They know of all the possibilities and take due care to ensure their own safety as well as that of your equipment.
If You Can’t Find Exact Replacement Of Contactor
Our recommendation is to always replace a contactor, with the same make and model as that of the original one. Although it is possible that you don’t find an exact match. If that happens, be sure to buy one with terminals that are similar to the one you took out. Most importantly, make sure that the voltage rating is exactly the same as well as its load capacity or amperage.
Your AC contactor is a small switch like device which has a very important job to perform. During the course of annual maintenance, you should ask the HVAC technician to take a look at it as well. If need be, ask them to clean its contacts to increase its productive life. If your AC is not giving cool air, ask the technician to check the contactor for any faults. Though the issue may not be with the contactor, it is necessary to rule it out as a possibility. If you are still not convinced, you can always ask for a second opinion.
We are so used to living in an ideal climate-controlled environment in our homes that it does not matter how the weather is outside. It may be blazing a winter storm outside, but you would be enjoying a warm summer-like climate inside the home and vice-versa. All these thanks to the modern air conditioners. Today’s air conditioners give cool air in summers and warm air in winters, thereby keeping the home comfortable pleasant all year round. A machine which is used so often can suffer breakdown due to a multitude of reasons. One of them being a fried circuit board. Through the medium of this post, we shall try and educate you more about its causes and how to bypass the AC circuit board.
Causes Of A Fried Circuit Board
The common causes which can burn or fry a circuit board are –
1. Power Surge – When there is a power surge, the circuit breaker should trip. If that does not happen, the circuit board can fry because of high voltage which it is unable to handle.
2. Wrong Fuse – The kind of fuse that is used in your AC depends on its power. If a small fuse is installed, it will be unable to handle the load of your AC and in turn, fry the circuit board.
3. Loose Wire – Wires which are not fitted or appropriately tightened can cause a short circuit. When that happens, the probability of the circuit board to burn increases.
4. Clogged Filter – Accumulation of dirt and debris over a period of time clogs the air filters. This puts tremendous pressure on the blower motor. As a result, it overheats and burns the fuse which can again make the circuit board go bad.
5. Faulty Capacitor – If the starting capacitor itself is not working properly, it puts a strain on the entire unit. One of its effects could be a burnt circuit board.
6. Weak Blower Motor – Sometimes the blower motor fails. When it fails, the fuse blows, and the AC unit draws too much power. This high power causes a short circuit and burns out the circuit board.
How To Bypass AC Circuit Board
It is highly recommended that you do not bypass the AC circuit board without good reason. Even then, it is advised that you let a trained technician do this job.
For your knowledge, let us understand what exactly needs to happen so that your AC starts giving cold air.
1. First, what needs to turn on is the condenser.
2. The second thing needed is the blower motor.
First Step – Open the fuse box in your home and identify the AC’s circuit breaker. Flip this breaker to the “Off” position. If you are not sure which particular breaker is for your AC, turn off the main breaker which supplies power to your entire home.
Second Step – As a precautionary measure, locate and turn off the power switch that controls the outside compressor unit of your AC.
Third Step – First thing to check is that the transformer is providing a current of 24 volts. If not, you may either replace the transformer or connect it directly to the line power.
Fourth Step – Attach one side of the 24-volt wiring from the transformer to the wire that goes out to the contactor of 24-volts. You can find it in the outside ac condenser unit. If there is a blue wire, use that one to complete this step.
Fifth Step – Attach the other side of 24-volts from the transformer to the red wire. Ensure that the other end goes to the R terminal, which is in the thermostat.
Sixth Step – The next step is to ensure that the other side of the contactor in air conditioner connects to the Y terminal of the thermostat. For this, use the yellow wire. Ideally, it should already be that way. If it is not, you will have to make it that way.
Seventh Step – Connect the high volt, line-in, power directly to the blower motor. This will get the blower motor running continuously to keep your home cool.
Eighth Step – Flip the main circuit breaker or the AC specific circuit breaker back to “On” position, as the case may be. Also, turn on the power switch to the outside compressor unit.
Bypassing the AC circuit board is only a temporary solution. It should suffice until you are able to buy the requisite circuit board to replace the one that fried. Do not use this as a permanent solution.
AC Circuit Board Troubleshooting
In an AC, you need to have proper input in order to get the desired output. However, this is one aspect which is based on technical knowledge. A regular person with no electronics or engineering background will find it challenging to analyze this. Further, whether the problem arises due to a bad circuit board or something else entirely is also tricky. A trained HVAC technician can do this analysis in just a few minutes rather than the hours that you would take. Moreover, they can identify the problem correctly and advise you the best course of action as well. In the interim, if required, they can also give you options which can have you continue living in comfort until the necessary repairs or replacement can be carried out.
How to bypass AC circuit board may seem as simple as disconnecting a few wires and reconnecting them elsewhere. But, do not be fooled by the simplicity of the steps involved as there is no scope for error. Your AC is a piece of expensive machinery. Your mistake may fry your AC beyond repair. That would be a costly blunder. Let people who are trained for these jobs handle the sensitive issue. From your end, all your AC demands are gentle cleaning and regular maintenance from trained personnel. Other than that, you need to just sit back and relax in the cool air of your air conditioner.
Troubleshooting your AC problems is not an easy task. But surprisingly there are many which you can actually take care of yourself. You need not be an engineer to get a handle on them. Instead, all you need is a helping hand in the form of a useful and informative guide. In that context, here is a little guide which will help you understand the AC contactor failure symptoms and what to do when that happens.
What Is AC Contactor?
Yes, we know you must be wondering “what on earth is an AC contactor”? A contactor is an electrical transmitter or relay in the AC. It regulates the flow of electricity to various parts. For example, the contactor sends current to the condenser as well as the outdoor fan motor. Basically, a contactor allows or prevents power to the AC unit.
In layman terms, it is an electrically controlled switch which is used for switching an electrical power circuit. Usually, a contactor is controlled by a lower power level circuit than the switched circuit. For example, a coil electromagnet of 24-volt controls a motor switch of 230-volt.
What Does The Contactor Do In AC?
In an AC the contactor closes to create an electrical circuit. This allows your AC unit to start when the thermostat sends the signal for cooling or heating. When the thermostat calls for heating or cooling, a magnetic action occurs. This forces a connection between the contactor’s volt side (line side) and the load side. The load side is one where the compressor and fan motor are coupled. When the thermostat halts calling for action, the contactor opens. When the contactor opens, it stops all power to the AC.
What Happens When The Contactor Is Faulty?
When the contactor develops a fault or goes bad, it may need replacement. In such a case, it will not pull close. When that happens, the two ends do not connect with each other even when the current is directly run to it. In case your thermostat is clicking on; however, the unit itself isn’t operating, the contactor is most likely completely gone. If that is not the case, it is not getting the much-needed electric current.
AC Contactor Failure Symptoms
There are 3 main signs which indicate a bad contactor in your AC. These are –
1. Chattering – the plunger tends to chatter when the contacts are dirty or when the coil has become weak. The chattering sound can be heard when the plunger is trying to make contact but is unable to do so completely. It fails to engage and instead produces the sound.
2. Humming – When the AC is turned on, you hear a humming sound; however, it does not power on. The humming sound is made by the coil, but the contact is still not made as the button isn’t being pulled in. Manually pushing in the button will get your AC unit functioning normally. The humming sound is also an indicator of weak coils or dirty contacts.
3. Melting – In really extreme cases, you may see that the plastic molding or the plastic casing on the contactor has melted. This too points towards the fact that the contactor needs immediate replacement.
Repairing Or Replacing A Contactor
One thing pretty evident from the above discussion is that there are 3 main reasons for the AC contactor failure. These are –
1. Dirty contacts
3.Complete breakdown or burnout.
In either of the above cases, it is possible to carry out repairs, but ideally, they are not worth the effort. It would be much better to replace the defective component. In the long run, it is a more financially feasible decision. These days replacements are readily available and that too for a fraction of the cumulative repair cost.
Dirty Contacts – On a contactor, there are points of contacts which become corroded, charred, and sometimes even dirty. These can easily be cleaned with the help of some contact cleaner. Go light on the cleaner as the points of contact are really small; there is no need to douse them in the cleaner.
Weak Coils – In case of coils repairing is not possible. They can only be replaced. Replacing just the coils in the contactor is a tedious and troublesome task. It involves taking out the contactor from the AC and then dismantling it to reach the coil. A much more feasible and quick approach is to replace the entire contactor. Residential unit contactors are relatively cheap and cost anywhere between $20 to $30.
Complete Burnout – Complete burnout means there is no life left in the component. That is why it cannot be repaired; instead, it can only be replaced.
While replacing keep in mind the specifications of the original component and replace with one which matches all those. Replacing is easy; all you need is a flathead screwdriver. Switch off the power to the AC unit. From the contactor, disconnect the wires. Remove the feet from the unit by unscrewing. Now, on the new part, screw the feet back on the unit.
Finally, reconnect the wires and the job is done. This job you should do only if you are sure that you can do it properly. Else, call an AC technician to take care of the problem for you.
Save Your AC
Had all air conditioner problem solving been easy, you would never need an AC technician or for that matter the various HVAC companies. The fact remains that your AC is a delicate piece of equipment and needs to be handled carefully. This is why it is strongly suggested that instead of taking matters in your own hands, you should let people who are trained for the job take care of them.
If however, you have the technical know-how to deal with the issues, you can save a great deal in repairing and replacement costs. Whatever you decide, always remember to switch off the power supply to the AC unit whenever carrying out any activity related to repair and maintenance. Also, have your electrical safety knowledge up to date and be extremely cautious.
A bathroom is a sacred place. You go there first thing in the morning, the last thing in the night, and many times in between. Since you frequently use it you want, all items must be clean, tidy, and in proper working order.
It is the place where you find solace in the form of a nice long soak or a fast rejuvenation of the tired soul through a quick shower. Sometimes you may even go there to hide from your little brats and get some quiet time.
At such times, even a leaking and dripping faucet is a big irritation. Even worse is you go in for a bath, and when the time comes to turn off the faucet, it just doesn’t do what it is supposed to. Not only is your precious water running away, but it may also damage the floor and walls. This is a tricky situation and a valid cause for concern. The purpose of this article is to reduce your anxiety and tell you exactly how to proceed when your bathtub faucet won’t turn off.
What To Do When Bathtub Faucet Won’t Turn Off
The situation calls for an expert, which in this case is the plumber. However, he is not waiting at your doorstep, so you need to get a handle on things yourself. The apparent solution is repairing the faucet yourself. It’s an excellent time to learn the basics of faucet repairs now so that in future you can take care of things on your own.
Fixing The Faucet
Sometimes the problem is really simple and needs just a small fix. To begin with, your first course of action should be to tighten the handle screw.
Step 1 – Since the flow of water has not stopped, you need to shut off the water supply completely. The valve that controls the water supply to your home will be somewhere close to where your water heater is fitted.
Step 2 – Take a pic of the faucet and its handles. It will come handy while buying new parts or explaining to the plumber.
Step 3 – Using a flat-blade screwdriver, pry beneath the cover plate to reveal the handle screw. Sometimes tightening this screw will solve the problem. Use a Phillips screwdriver to tighten it.
Step 4 – Restart the water supply to your home and turn the faucet on and off to see if you have managed to fix the problem.
If tightening of the handle screw does not solve the issue, it’s time to aim big. You have to try and repair the end of the stem.
Step 1 – Again, you need to begin by turning off the water supply so that you do not flood the bathroom.
Step 2 – From the faucet, you need to remove the handle. For this, rotate the handle until it comes off the stem. You may need to use a wrench to complete this action. At times, a gentle pull can also do the trick.
Step 3 – Examine the faucet stem end for any kind of damage. Ideally, the stem tip has rims or ridges which attach to the ridges that are inside the handle of the faucet. When these get worn or spoiled, the faucet handle is unable to tighten around the stem. Due to this reason the faucet unable to turn off. You need to replace the part whose rims have smoothened out over a period of time.
Step 4 – Carefully have a peek inside the faucet handle to detect any obvious damage. A handle which is cracked would need complete replacement. Again, this because it will not grip the faucet stem correctly. When the grooves or ridges inside the handle get worn out, the handle can’t attach with the stem properly. As a result, it cannot regulate the faucet.
Step 5 – Clean the stem end to remove any deposits or debris. You can use an old toothbrush to do so. Once done, with the help of a rag wipe the stem dry.
Step 6 – Wrap a couple of layers (one or two) of thread-seal tape all around the valve stem tip. Now, push or firmly press in the handle over the stem through the layers of thread-seal tape. Another way is to rotate the handle over the stem until it locks in position.
Step 7 – Finally, turn on the water supply once again to check whether the fix works or not. If it works, remember, the thread-seal tape is a temporary fix. It will increase the life of the faucet stem and handle from anywhere between a few months to a year or two. Ultimately, you just have to replace them.
When Your Fix Doesn’t Work
It is not necessary that your repair will hold for long or that it even fixes the problem. If the problem does not fix at all, shut down your water supply and call the plumber immediately. If your fix works only for a short duration, you are probably not doing it correctly. Even then you need to call the plumber to come and address the issue once and for all.
Tips To Keep In Mind
1) Cover the drain with a cloth so that no small pieces or spare parts fall into it. These can clog the drain and also make for unnecessary purchases to replace them.
2)Put a protective sheet in your tub so that you don’t accidentally leave scratches or stains of any kind.
3) When working with pipes, wear protective gloves. This way, you will not hurt yourself on any sharp edges.
4) Wearing safety goggles is also advisable so that you don’t get any stray particle inside your eye.
What We Advise
Some works cannot be done by all. There are professionals who are trained to handle them. Having said that, it is not possible to get hold of these people at a moments notice. A plumbers job is one such. In the absence of a plumber, you need to be knowledgable enough to handle a minor crisis. You need to know the basics of handling any situation so that your suffering is limited. Hopefully, this article will help you in the future.
One thing that all Florida residents can do to keep their homes suitably warm (in winters) and cool (in summers) is to get regular maintenance done of their HVAC units. In an ideal scenario, it should be done every 6 months, so twice a year. The most appropriate time is just before the start of summers and winters, respectively. To save some work for yourself, what you can do is find a local HVAC company and sign an HVAC preventive maintenance contract with them. An annual contract is best as it will give you a chance to access the company and judge whether you are satisfied with their service delivery or not. If you are happy, you can go for an extended contract or look for another more suitable option.
What Is HVAC Preventive maintenance?
HVAC preventive maintenance is the top to bottom and inside out maintenance of your HVAC unit or air conditioner to ensure peak performance and trouble-free operations. It entails superficial functions like cleaning the unit and tightening nuts and bolts. It also includes duct cleaning, topping the refrigerant to the appropriate level, cleaning the coils, changing the filters, etc. In a few words, HVAC preventive maintenance is all about thorough servicing of your heating and cooling unit along with its ventilation. Some services are free as part of the contract, and for others, you pay an additional amount.
Are HVAC Preventive Maintenance Contracts Worthwhile?
Usually, homeowners are a little skeptical about purchasing an HVAC preventive maintenance contract. The primary reason for their concern is: Cost. An HVAC service contract can value anywhere between $150 to $500 annually.
If your HVAC unit is still new and under the manufacturer’s warranty, this additional expense does not seem worthwhile. Be that as it may, the manufacturer still demands routine maintenance for the warranty to remain in effect. It is quite possible that the service contract may cost more than the cost of repairs and service put together. Regardless of any repairs not done, you will still have to pay the contract price each year. An ideal solution would be to purchase a service only contract and pay for repairs additionally as and when they arise.
Benefits Of HVAC Preventive Maintenance Contract
The key benefits of HVAC preventive maintenance can be summarized in the following points –
1) Extends The Life Of Your HVAC Unit – Your HVAC unit gets dirty and repeated use results in wear and tear of various components. When you fail to address these concerns, the unit operates under tremendous pressure. As a result, it will malfunction quite often, and in the end, give up altogether. If you take good care of your HVAC unit through regular maintenance, the likelihood of any such occurrence diminishes considerably. Periodic maintenance will give the unit a new lease of life so you can enjoy its usefulness for a more extended period.
2) Keeps Warranty Intact – The warranty of your HVAC unit remain intact only if you take the trouble to get it serviced periodically. Failing to do so will revoke the warranty. Manufacturers insist on getting the maintenance of each unit done so that they perform better and give as little problem as possible. In the absence of maintenance, the problems will just multiply for which the manufacturer will not take any responsibility. If you did not get your HVAC unit serviced, you propagated the problem. In this case, the manufacturer cannot be blamed and held liable for repairs.
3) Safety Of Your Home – Especially in winters, you do not want the disaster of burst pipes to cause water damage in your home. If the heating is proper, you will never have to lose sleep on such trivial matters even when you are away on vacation. In your absence, your HVAC unit will see to the safety of your home. In the same manner, any loose wiring will be caught during maintenance and tightened. This will remove fire threat due to short circuit. The HVAC also improves the air quality inside the home and gives you lesser cause for concern from a health perspective. Its periodic maintenance also does away with the fear of carbon monoxide poisoning.
4) Ensures Best Performance – Maintenance sees to it that your HVAC works to the best of its capability at all times. During maintenance, it is tuned, tightened, and cleaned to make sure nothing causes hindrance in its optimal working. It translates to smooth operations, lesser power consumption, lesser electricity bill, and comfortable temperature inside the home always.
5) Lesser Repairs – A well-maintained HVAC unit will give less trouble as compared to one in which maintenance is completely overlooked. The reason being, maintenance forces the homeowner to take care of the issues at the earliest before they become significant problems. For a far lesser cost, a small problem can be resolved before it escalates into an expensive repair or replacement.
Research HVAC Contracts Before Buying
First and foremost, validate whether there is any saving in signing the HVAC preventive maintenance contract. It is quite possible that the cheaper option is to pay for routine maintenance from your pocket without any contract. If you do decide that the better option is an HVAC maintenance contract, see to it whether it includes emergency repairs. Also, read the fine print for additional terms and conditions which could have an impact on the contract.
Food For Thought
No matter what course of action you decide upon, make sure that the company who handles your HVAC is reliable and trustworthy. Your service contract is as good as the company that backs it. On the same note, an independent contractor is also as good as the number of satisfied customers he has. Consider the financial benefits of the two and choose the one which gives you the best value for money. HVAC preventive maintenance contract may be the answer to all your recent HVAC woes. Don’t just rule it out because it is a little costly.
Life would be so much easier if someone were to give you a checklist of things you need to do in order to maintain your divine abode. Taking care of it all the year-round may seem like a daunting task, but it is something that you have to do diligently. Your home is your sanctuary, a place that is your own, a place you come back to at the end of each day.
Taking good care of it will not only increase its lifespan but also prevent small issues from becoming big and costly concerns. So, we decided its time for some divine intervention (Ahem! More like Aztil AC intervention). In an endeavor to make your life easy, here’s a seasonal home maintenance checklist, especially for you. It’s even more helpful to those who reside in Florida.
Home Maintenance Checklist
You have made the right decision to take care of your life’s most significant investment proactively. The checklist below will help you stay on top of all the jobs that you need to attend to in order to preserve the value of your home. For ease of convenience, we shall break down this checklist in two portions –
1. Seasonal home maintenance checklist.
2. Periodic home maintenance checklist.
Seasonal Home Maintenance Checklist
Season to season the cleaning and maintenance requirements keep on changing. Here is a list of jobs you need to complete for each season –
1) HVAC servicing should be a top priority. Your central air conditioner split AC, or window AC needs to be serviced by a trained professional so that it is all set to run with maximum efficiency and minimum problems in the coming summers. If you wait until summers to get this job done, you may have to wait longer due to the high demand for HVAC technicians during that time.
2) Clean the gutters and drainage. You can’t wait for the rainy season to start before cleaning them. By then, blocked drains and gutters will cause serious troubles in the form of damp of ceiling and walls. In turn, this will result in mold formation.
3) Replant your garden. If you want to get landscaping done or replace a few plants and sow a few new seeds in empty patches, now is the time to do so.
4) Clean windows and screens so that there are no remnants of any winter debris. If anything needs repairing, it should be done now.
5) Inspect the foundation for any cracks. These need to be filled before the advent of the rainy season.
1) Get the heavy laundry done. For example, if you want to wash your carpets and other upholstery, now is the time to do so. The hot summer sun will aid in their drying and also kill bacteria.
2)Air out your home because a better opportunity will not present itself. It means open those closed windows, clean the chimney, and vacuum the ducts.
3) Don’t forget your clothes dryer. It needs to be cleaned. Suck out the lint with a vacuum cleaner and check for any blockages if the exhaust is minimal.
4) Check the garage sensors while the sun is still out.
1) Trim the foliage and clean the drains to keep your landscaping clean and pristine.
2) Check all the sliding doors and windows for smooth and slick operations.
3) Drain the hoses and store them properly.
1) Clean that garage for some necessary activity and to catch some sun. Get rid of all the unwanted stuff and organize all that remains.
2) Repair the cracks in the foundation before the spring thaw.
Periodic Home Maintenance Checklist
You can also perform the home maintenance jobs on a monthly, quarterly, semi-annual, and annual basis.
1) Change AC filters every month. If you can’t change them, clean them rigorously with a brush and water until all dust and debris are removed.
2) Flush the toilets that are not in use. This will keep them in proper working order.
3) Run water through sinks which are not used often.
4) Clean the electric chimney in the kitchen.
5) Mow the grass in front yard and backyard.
6) Check the level of salt. If required, add more. Also, make sure that no error code is displayed. In case it displays an error, get it rectified immediately.
7) Check water softener.
1) Check the drains on the outside to ensure there is no standing water. Clean all such things like leaves, twigs, stones, and other debris that can clog them.
2) Lubricate all doors and windows so that they open and close smoothly. Include the garage door as well.
3) Trim the trees, hedges, and other foliage which is growing out of proportion.
4) Clean the gutters and all the weep holes to ensure proper and efficient water drainage.
Semi-Annual Job List
1) Clean and disinfect all the appliances in the house, especially the refrigerator, dryer, water tank, etc.
2) Deep clean the carpets, curtains, sofa, meshes (on doors and windows) and any other similar items to keep them hygienic and smelling nice.
3) Check for cracks in the foundation and sheetrock, loose tiles and floor. Fix them as soon as possible.
Annual Job Card
1) Get complete maintenance of your HVAC unit done by a trained technician.
2) The tank of your water heater needs to be flushed to prevent sediment buildup and corrosion.
3) Pest control treatment should also be done once a year.
4) Thoroughly clean all the ducts and vents in the house.
We have tried to make the seasonal home maintenance checklist as comprehensive as possible. However, it is by no means an exhaustive list. To suit your requirements, you may add more things to it. Cutting it short is not advisable. It includes the minimum items that you have to check to maintain your house in a tip-top manner. We hope this list meets all your needs and lives up to your expectations.
The compressor is the very heart of an air conditioning system, for that matter any cooling system. Suffice to say without the compressor; there will be no cooling. But how well do you know this heart? In fact, were you aware that a compressor has at least 5 different types? If not, you need to read this article to learn something new. You never know when the information may come handy.
What Does The Compressor Do?
The compressor compresses the refrigerant in the gaseous state, thereby raising its temperature. This temperature increase changes the refrigerant to high-pressure gas. The subsequent high pressure pushes the refrigerant through a pipe, which leads to the outdoor coil. Here the refrigerant dissipates its heat and condenses into a liquid form. The liquid refrigerant continues to travel to the indoor unit, where it evaporates and attains the gaseous state once again. During this process, it absorbs the heat from within your home. The refrigerant then travels back to the compressor, and the cycle starts all over again.
What Forms The Basis Of Different Types Of Compressors?
The primary function of the compressor is to provide the cooling effect. If they all perform the same function, then how are they different? The answer to this question is straightforward. Though the compressor performs the same function, they work in varying ways, which forms the basis of their type.
Types Of Compressors In AC
As stated above, there are mainly 5 types of compressors used in HVAC installations.
1. Reciprocating AC Compressor – With a construction similar to that of an automobile engine, the reciprocating AC compressor is by far the most popular presently. A piston, fitted inside a cylinder, compresses or tightly packs the air by moving up and down. This rotating motion is accomplished by using an electric motor. When the piston travels down, it produces a vacuum effect which draws in the refrigerant. When it travels back up, the gas gets compressed and passes into the condenser. This type of air conditioning compressor is extremely efficient, as AC units can house multiple cylinders. Though 2, 4 and 8 cylinder compressors are most commonly used.
2. Scroll AC Compressor – Also known as a scroll vacuum pump or a scroll pump, this type of compressor has two scrolls. One of these is an immovable scroll and the other a revolving or circling scroll that rotates using the swing link. Due to this motion, the refrigerant pockets amidst the two scrolls are gradually pushed to the middle of the scrolls. When this occurs, there is a decrease in the gas volume. It then passes to the condenser through the center port. The prime benefit of a scroll compressor is that it has lesser moving parts and smaller torque variation as compared to the reciprocating AC compressor. This translates to a comparatively, smoother, and quieter operation. For this very reason as well as their reliability and efficiency, Scroll AC compressors are fast gaining popularity.
3. Screw AC Compressor – The screw air conditioner compressor is very dependable and efficient. It is mostly used in large structures where there is a significantly larger amount of air that needs incessant cooling. Using a pair of helical rotors (male and female), which move from one end to another in a revolving motion inside the cylinder, the refrigerant gas is compressed. Ideally, this kind of compressor is used in HVAC systems that have a capacity of 20 tonnes or more.
4. Rotary AC Compressor – Rotary compressors are of two types. One has slats or vanes which rotate along with the shaft. The other has fixed blades and is part of the unit which houses the compressor. In a single system, the blades can vary in number from anywhere between two to eight. In either type, the gas from the suction line is dragged inside the cylinder via the suction port. Rotary compressors are generally small and silent, so they are widely used in places where noise is a grave concern. The inside of a rotary AC compressor houses a shaft with some blades attached to it. The shaft with blades rotates inside a graduated cylinder. This motion pushes the refrigerant through the cylinder and compresses it at the same time.
5. Centrifugal AC Compressor – Centrifugal AC compressor uses centrifugal force to drag in the coolant or the refrigerant gas. Then it spins the gas rapidly with an impeller or a disk with radial blades to compress it. The pumping efficiency rises with speed. Higher the speed better the pumping efficiency. As such, these compressors are intended to function at high speed. The key benefit of a centrifugal compressor is that it has no valves, pistons or cylinders. The only wearing parts that demand care are the main bearings. These types of compressors are usually used in a large capacity cooling system and hence are earmarked for extra-large HVAC systems. In short, they are most suited to industrial installations.
Which Type Of Compressor Is The Best For Air Conditioners?
If the AC unit is of small capacity, say up to 10KW, a rotary compressor is the best. However, if the AC unit is of medium size capacity, from 10KW to 50KW, scroll compressors are more suited. Ultimately, its a toss between sacrificing a little silence for more reliability and efficiency, or vice-versa.
Innovation is the key to technological advancements. In the arena of AC compressors, great strides have already been made in trying to fulfil the varying demands of the consumers. The result is the different types of compressors in AC. This is nowhere near the end, but a niche has been carved so that people can choose what suits their needs the best. With its own set of pros and cons, each compressor offers something unique to the buyer.
Ultimately the decision regarding which compressor is best suited for your requirements will depend on how clear you are in what you want the most and where you are ready to compromise.
Power outages are a normal occurrence. Usually, by themselves, they are no issue, but sometimes they bring with them some minor to major problems. Electric hot water heater not working after a power outage is one such problematic situation. Depending on what has gone wrong with the water heater, it could either be a minor thing or something as significant as a dead water heater.
Water Heater Takes Time To Heat Water
If you have used up all the hot water while the power was out, you have to give your water heater time to heat more water. It is not an instant heating device. Water heaters operating on gas take around half an hour to 40 mins to heat a tank full of water. An electric heater takes around twice as long. Even after the passage of this time if there is no hot water, you have cause for concern.
Check The Power Supply
The power is back up inside the home, but it’s entirely possible that the power supply to the water heater is still not through. There is a probability that after the outage, only partial power was restored and not complete due to some fault. Maybe your water heater is one of the affected appliances. Using a “circuit tester”, you can check whether your water heater is receiving power or not. If not, you need to figure out why. There are a couple of reasons that could be the cause. These are –
1. Tripped Circuit Breaker – Due to a surge in electricity, when the power came back on, the circuit breaker may have tripped. To rectify, you will have to push the tripped circuit breaker back to “On” position. Once that is done, your water heater should start functioning normally. However, if the circuit keeps tripping, it’s better to ask your local HVAC technician to come and have a look at the problem. Remember the circuit trips only when there is an overload. So, maybe you need to reaccess your electricals and wiring.
2. Cut Or Burnt Wires – While the power was out, a small animal or rodent could have chewed the wiring leading to the water heater. Similarly, the wire may have been cut by mistake or burnt due to overheating. Whatever be the case, the power came back on, but since the wires were damaged, the water heater could not function. You will need to figure out where the wires were cut, chewed or burnt and replace them. Since this job needs to be performed correctly due to its hazardous nature, let your plumber or electrician deal with it.
3. Faulty Switchboard – The fault could also lay in the switchboard from where the water heater is powered. Maybe the earthing is not proper, or it has a loose connection. If you have some basic idea of electricals, this is something you can check on your own. In case you have any misgivings, it’s best to call your electrician.
4. Plug Problems – Just like a faulty switchboard, the plug that connects the water heater to the power supply source too could have loose connections. Open the plug and tighten all wires. If any wire is hanging free, put it in its correct position and tighten the screws. Your water heater should be all set to take care of your household demands for hot water.
All the above are possibilities when the water heater is not receiving power. If, however, its power supply is on, you need to look at a few additional things such as –
1. Thermostat Malfunction – The thermostat of the water heater could have malfunctioned; the power outage was just an excuse. Try resetting the thermostat by first bringing it down to zero. Wait for a couple of minutes and take it to the desired temperature. Hopefully, your water heater not working after power outage should be resolved. If this does not work, the chances are that you may have to replace the thermostat itself. Call your local plumber, to check it out and replace it, if required.
2. Low/High Voltage – Your water heater needs a certain minimum voltage to operate. Most residential water heaters operate at 220/240 volts and some at 110/120 volts. If the voltage is less than the minimum or higher than the maximum, as a safety feature, it will shut down or not function. If your water heater is not getting adequate voltage, it is probably because there is a problem with the electrical system of your home. You need to get this checked immediately by a trusted and qualified electrician. Once the voltage is back to normal, your water heater will resume functioning on its own.
3. Burnt Heating Elements – Quite possibly, the heating elements of your water heater have all burnt out. This is usually a gradual process and happens as your water heater gets older. You can try replacing the burnt elements to extend the life of your aging water heater. To be honest, if your water heater is more than a decade old. it is recommended to buy a new one.
4. Tripped Reset Button – Another possibility is that your water heater’s reset button has tripped. A faulty thermostat, shorted heating element, and loose wiring may be the cause of this trip. Until you correct this trip your water heater will not work. This reset button is usually red in colour, and when it trips, it pops out. You have to push it back in.
A power outage on its own will never harm a water heater. However, when the power comes back, a sudden voltage surge can fry the water heater. This will happen only if the circuit breaker does not work. It is thus essential to make sure that the electrical system of your home is reliable and trustworthy. Other than that, your local plumber or plumbing company should be able to take care of any water heater problems. Do not ever tinker with your water heater on your own. It is not a toy you can play with.
A few minutes into your nice, warm, and relaxing shower, you feel the water turning cooler. By the time 10 mins are up, you are completely out of hot water. There goes your dream of letting the hot water soothe your sore and tense muscles. It’s like a splash of cold reality. Sadly, for many of you, it might seem like an everyday occurrence. For others, it might be something you would want to prevent. No matter which category you fall in, you would not wish to run out of hot water when you want it the most.
Have you ever wondered why your hot water runs out after 10 mins while earlier it used to last longer? The truth of the matter is that there are just two plausible causes of it.
1. Increased consumption of hot water.
2. Something is wrong with the water heater.
Increased Consumption Of Hot Water
Hot water is used not just for bathing, but also for washing clothes and dishes. We tend to use it in the bathroom sink for shaving, brushing, washing face, etc. In addition to that, your family size may have increased, thereby increasing the hot water consumption.
What we are trying to say is that there is a high possibility that you have outgrown your current water heater capacity. What you need to do is take stock of how much hot water you are consuming daily and the capacity and efficiency of the water heater to fulfil that demand. If you think that the consumption is more than what the heater tank can hold –
1. You need to upgrade to a water heater with a bigger tank capacity.
2. Refrain from wasting and unnecessarily using hot water.
Something Wrong With The Water Heater
Your water heater is a piece of machinery built of various parts and components. The possibility of it breaking down cannot be discarded. So, what are those things that can go wrong with the water heater such that hot water runs out after 10 mins?
1. Sediment Buildup – Mixed in water are solid particles of minerals, sand, and other debris. Though they are very small in size, over a period of time, they tend to accumulate and form a layer. The thicker the layer, the more space of the tank it occupies and lesser becomes the capacity to hold water. Not only that but sediment buildup also decreases the efficiency of the water heater. It does not heat the water as much as it used to earlier.
The Solution – Make sure that there is a filter in your water heater to catch all impurities. A good water filter will only capture those substances which harm the heater. After that, flush your water heater. In order to flush it, you will first have to empty the tank and thoroughly clean it with fresh water. You can follow the heater manufacturers guide and do the job yourself, or you can call your local plumbing service to do the job for you.
2. Faulty Thermostat – The thermostat mounted on the wall, which controls the temperature of your home isn’t the only thermostat that you need to worry about. Your water heater also has one. Just like your AC thermostat this thermostat too can develop faults.
The Solution – Before doing anything else try resetting the thermostat of your water heater. If that does not work, increase its temperature, for all you know it was the temperature which was set incorrectly. However, if neither of these two tricks works, you might want to call your plumber because your thermostat might need to be replaced.
3. Worn Out Parts – As mentioned at the beginning of this section, your water heater consists of many parts. As it ages, the parts become worn out or get damaged due to constant use. The most common part that gets damaged is the “Dip Tube”. When it gets worn down, it leads to the mixing of cold and hot water. So, you feel as if the hot water runs out after 10 mins.
The Solution – A damaged dip tube has to be replaced. There is no other solution. However, if your water heater is more than 10 years old, it’s probably time to replace it. In an old water heater, sooner or later other parts will also start going bad. So, instead of replacing each damaged part, it’s more economical to buy a new water heater.
4. Heating Element Burned Out – Every water heater has elements which heat up to make the water hot. Constant use can burn these elements. When that happens, water does not heat properly.
The Solution – The only solution to this problem is to ask your plumber to replace the heating elements. Ideally, heating element spoils only in old heaters. If your new heater has this problem, it needs to be checked out.
5. Leaks – Leaks in the tank of the heater as well as the pipeline can also result in less hot water. Usually, leaks would occur due to corrosion or pipes bursting when they freeze. In either case, all the hot water does not reach inside the house for your consumption. Some of it gets wasted as it flows out of the cracks and leaks.
The Solution – You need to find the points of leaks and seal them. If needed, change the damaged part completely. Depending on how comfortable you are handling this job yourself, either you can do it or ask a professional plumber to do it for you.
In The End
Just like your air conditioner, your water heater also requires maintenance. It works day in and day out to provide hot water for you and your family. Taking care of it is essential. If, in spite of regular maintenance, you are facing hot water scarcity, its time to call in the professionals. They are the best judge and will give you apt advice. At your end, see to it that there is no wastage of water. It is a life-saving commodity and should be handled with care.
Smells of burning plastic coming from the air conditioner are not unheard of. When something works continuously for hours at end, it’s normal for them to suffer wear and tear. It is quite a common occurrence and can be easily remedied. So if your air conditioner smells like burning plastic, this post is just for you. But before we begin with the reasons lets understand a few basics.
What Does Burning Plastic Smell Like
Burning plastic smell is very distinctive. Unlike the smell of mold and mildew, which smells like dirty socks, the burning plastic smell is pungent and unpleasing. Depending on the intensity of the heat, the smell can be light or strong and hard to ignore. No matter what, whenever you notice this smell take immediate action.
Is Burning Plastic Smell Dangerous For Health?
When plastics burn, they release harmful chemicals into the air. These chemicals can cause difficulty in breathing and other respiratory disorders. Additionally, some of them are potentially carcinogenic. So, Yes, the burning plastic smell is dangerous for health.
Can The Burning Plastic Smell Be Ignored If Its Light
Even if the burning plastic smell is not very strong, it is in your best interests to not ignore it. Not only is it hazardous to health, but it is also an indication of a potential fire hazard. It should be dealt with immediately without any delays.
Reasons Why Your Air Conditioner Smells Like Burning Plastic
The most likely reasons why your air conditioner smells like burning plastic are –
1.Dust Burning Off – In most parts of Florida, there is no need to switch on the “Heating Mode” of AC. During a cold front, when suddenly the need arises, you may observe a burning smell. This smell originates because the AC is burning off the accumulated dust. In a few minutes, this smell will go away on its own. If this smell is coming in the “Cooling Mode”, you need to immediately shut down the AC.
2. Broken Capacitor – A capacitor is that part of the AC which helps the motor run. If for some reason, like a power surge or a short circuit, the capacitor spoils it puts pressure on the motor causing it to overheat. When the motor overheats, it gives off a burning plastic smell due to proximity to other plastic components.
3. Overheating Motor – The fan that throws hot and cold air throughout your home needs a motor to work. The bearings of this motor get worn out due to extended use and overheat the motor producing burning plastic smell. This is a normal occurrence and nothing to be alarmed about. Lubricating the bearings of the motor will fix the issue. If you are comfortable handling this on your own, you can do it yourself. Else, ask an HVAC technician to come and do the needful.
4. Tear Or Break In Fan Belt – Many air conditioners have a fan which is driven by a rubber belt. Often due to continuous use and temperature variations, the belt develops tears or breaks completely. In either case, it causes overheating and produces an unpleasant odor. If this is the case, turn off your AC and call an HVAC technician to replace the belt. This job is a little technical as the belt has to be adequately tight, so we recommend professional help.
5. Electrical Fault – An electrical problem may also result in your air conditioner smelling like burning plastic. Usually, there is a plastic coating on wires. In case of an electrical problem, this plastic covering melts and produces the foul odor. To figure out the problem, all the circuits in the AC need to be checked. This job is best performed by a trained repair technician who deals in air conditioners.
6. Clogged Filters – A dirty air filter impedes the free flow of air into your air conditioner, thereby putting unnecessary stress on the mechanism. This strain is especially borne by the motors, causing them to overheat and producing the burning plastic odor. Cleaning the air filters at regular intervals will prevent this from occurring.
7. Recirculating Fire Smell – A very important aspect of an air conditioner is that it recirculates air. It picks up air from within the house and recirculates it back into the house. The possibility is quite strong that there is a fire somewhere in the house and your AC has picked up that smell. If that be the case, look for smoke or the actual fire. If its nothing big and you can put it out yourself, do the needful. Else immediately vacate the home and call the fire station or 911.
How To Prevent AC From Smelling Like Burning Plastic
Time and again, stress has been put on the importance of regular AC maintenance. Your air conditioner smells like burning plastic; the chances are that you skipped on maintenance. As a result, your system was neither properly cleaned nor checked for loose wire connections and other minor problems which get covered under maintenance.
Our Point Of View
We are of the opinion; one should never take undue chances. The smell of burning plastic indicates towards the fact the something is heating beyond an acceptable level. It could either cause a fire or spoil an important component of your AC. The moment you notice this smell, switch off your AC and ask an AC technician to come and thoroughly check out your air conditioner.
Your AC is but a machine which consists of many parts. Due to constant running, one or more parts may suffer damage. This damage usually will come to the forefront in the form of some abnormality. It could be an abnormal smell, a decline in efficiency, or a tripping circuit. It may not necessarily indicate towards a big problem buy leaving things unattended could culminate to it. Regular maintenance of your AC along with prompt addressal of issues will go a long way in increasing its lifespan.
Only when both the indoor and outdoor unit of your split AC work does your home achieve the desired temperature. When either of the units shut down, your air conditioner will fail to do its job.
In winters maybe this will not cause you much trepidation but in summers it will jangle your nerves and set you on tenterhooks. In most cases, you will see that the outside AC unit is not running but inside is. When this happens, the air that blows into your home is not cool, just normal room temperature air.
How To Know Outside AC Unit Not Running
There are two indicators which point towards something being wrong with the outside unit of your split AC. These are –
1. No Sound At All – No matter how silently your AC operates, there is still a little hum that it produces, especially when the compressor kicks in. If your AC fails to produce any sound at all, even when the compressor is supposed to start, it means that something may be wrong with the unit that is installed outside.
2. Warm Air Blowing Into The Room – If in summers, the air that blows into the room is warm or at room temperature, it could indicate a problem with the outdoor AC unit. Typically, in warm weather, your AC should blow air, which is cool to lower the temperature and make it pleasant.
Reasons Why Outside AC Unit Nor Running But Inside Is
There could be a couple of reasons behind why the outside AC unit is not running but inside is. Some of these can indeed be addressed by the homeowner themselves, and for others, a trained AC technician is the only answer.
1. Accidentally Unit Switched Off – Typically, near the outdoor AC unit, there is an on and off switch. Somebody may have accidentally turned it to off position. When this happens, the outdoor unit will not work because the power supply to it is switched off. You just need to bring the switch back to on position.
2.Tripped Circuit Breaker – For this, you will have to open the circuit box to check if the circuit breaker for the outside unit has tripped. In case it has, you need to flip it back to on. However, if the breaker keeps on tripping frequently, the problem needs to be checked thoroughly so that your AC does not suffer any major damage.
3. Incorrect Thermostat Setting – The thermostat setting could go wrong for two reasons. The first being, somebody set the temperature higher than the room temperature. In this scenario, the outdoor unit will not start since the compressor is not needed for cooling the room. The second situation is when the thermostat develops a fault. If this is the problem, you will first have to ask the AC technician to confirm your diagnosis. Once he agrees, the thermostat will need to be replaced with a new one.
4. Clogged Drain Line – As a safety feature, the outdoor unit of some air conditioners stop working if their drain line is clogged. To remedy the problem unclog the drain pipe. Either you can do this yourself your you can ask your AC technician to do the same for you.
5. Broken Compressor – Only a trained HVAC technician can tell you if the compressor of your AC is broken. If it’s a minor issue, he may carry out repairs as deemed fit. In extreme cases, he will advise you to either buy a new compressor or a new outdoor unit. In either of the extreme cases, ask for a second opinion from a trained professional to confirm the problem.
6. Old AC – An AC which is more than 10 to 12 years old may develop faults due to massive wear and tear. In old air conditioners, it is not advisable to carry out repairs as they will just give temporary relief until the next problem crops up. Outside AC unit not running but inside is may be how the problem has manifested itself in your aged air conditioner. It’s time to retire it and buy a new one.
Try Resetting Your Air Conditioner
Your AC is but a machine which may decide to act weird at times. Outside AC unit not running but inside is may possibly be one way in which it decides to act up. A simple way to test this theory is by resetting your air conditioner. In some air conditioners, there is a “reset” switch. This switch is usually close to the outdoor unit. Try pushing this reset button; it may possibly start your outdoor unit. However, if your AC does not have this “reset” button, you can try turning off your AC at the thermostat. After turning it off, wait for at least 5 minutes and turn it back on again. If even then the outdoor unit fails to start, call for a professional AC maintenance specialist.
What We Think
Time and again, through various blog posts, we have laid stress on the point that not all of us have the basic know-how to repair our own air conditioners. Moreover, an AC is a piece of expensive machinery without which life is unthinkable these days. So, why take chances with it. If there is a problem, it is best to call a person who is trained and equipped to handle it. Your half baked knowledge may land you in more financial trouble than you thought.
In The End
Outside AC unit not running does not mean the death of your AC. It is an indication that a problem exists. If you want a complete analysis of the problem book an appointment with your local HVAC company. If you reside in Palm Springs, Florida, look us up. We are trained professionals who deal with all kinds of HVAC problems and provide 24/7 emergency services.
Modern technology is so sophisticated that one does not even realize its everyday presence. Look at the air conditioners of today; they operate silently and tirelessly to maintain a comfortable temperature in your home.
Everything is hunky dory unless they start acting weird or making noises. Any noise in an otherwise calm home can be distracting and disturbing to your peaceful life.
The most common noise that an air conditioner makes is the hissing sound. So, what is this hissing sound from AC and how to fix it? Well, tax yourself no more as this post will cover all that you need to know about the problem.
What Does Hissing Sound Like
When you let out air from a small opening, the sound that is produced is the hissing sound. As a child, you must have noticed how a leaky cycle valve made a sound as air was let out of it. It came out in a hiss. This is the sound that you are most likely to hear from your air conditioner.
Are All Hissing Sounds An Indicator Of A Problem
All hissing sounds coming from the AC do not indicate an issue. If the sound goes away in a few seconds, it is nothing to be worried about. On the other hand, if the sound is continuous, you need to be on the lookout for a potential problem.
What Is The Hissing Sound From AC
The hissing sound from AC could indicate to a couple of things that may need to be fixed.
1. Leak In Refrigerant Line – A gas leak or a refrigerant leak mostly occurs in air conditioners which are old and those in which maintenance has not been given priority. In old air conditioners, the coils which contain the refrigerant corrode over a period of time and develop cracks. Under high pressure, the gaseous refrigerant escapes from these cracks with a hissing sound. In the case of ACs seasonal maintenance has been overlooked, the refrigerant coils may freeze and in extreme cases even burst. This causes the refrigerant to come out with a hissing sound.
2. Leaky Internal Valve – There is a valve in the compressor which controls the pressure of the refrigerant. Often this valve develops a fault and starts to leak. When this internal compressor valve starts to leak, it produces a hissing sound.
3. High Pressure In Compressor – The AC compressor may malfunction due to very high pressure inside it. This can produce hissing, shrieking, or groaning sounds. If you hear any of these sounds immediately shut down the AC and call your local HVAC technician without wasting any time. Since the compressor is the most expensive component of your AC, it would be foolhardy to let this matter slide.
How To Fix The Hissing Sound From AC
Once you know where the problem lies, fixing the hissing sound coming from AC is not too complicated. Yes, it may be something that you cannot do on your own, but remember your AC is a piece of expensive machinery which is best left to the experts.
1. Fixing Leaking Coils – Ideally, only a trained technician should handle this job primarily because they can effectively detect all sources of leak and close them properly. Also, only they can tell you whether the leaks are worth fixing or you need to replace the coils. Besides, when a trained technician fixes the refrigerant leak, he will also test its effectiveness, and only once he is satisfied will he top up the refrigerant to the prescribed level. These are certain things which you may not be equipped to handle.
2. Fixing Faulty Compressor Valve – The only way to fix this problem is by replacing the faulty valve with a new one. Again, as this is something for which you will have to open up the compressor unit, it is best handled by trained personnel.
3. Fixing High Pressure In Compressor – In order to fix the high-pressure problem, it is necessary to understand its root cause. This is one thing which only a trained HVAC technician can identify. So your only option is to switch off the AC and call your HVAC company for help. While the problem persists, do not use your AC as it could kill your compressor completely.
When Is Hissing Sound Not A Problem
As mentioned in the very beginning, all hissing sounds need not be alarming. Sometimes it may be a normal sound which your AC produces in the course of its operation. If that is the case, the hissing sound will be short and small. It is very normal for the expansion valve to make this kind of noise. When the refrigerant gas present in the valve expands, it makes the hissing sound. Nothing to worry about here.
Sometimes the ductwork may also produce the hissing sound, but this will only happen at the start of a new cycle. If you find this sound irritating, just open up your air registers a little more. However, if the hissing sound is constant and high, you have to look for its cause. In some cases, the hissing sound may turn into a screeching or whining sound as well. Now you need to be worried and get your AC technician pronto.
Our Final Thoughts
Any sound which your AC was not making in the beginning but has now started to produce needs to be checked out. There is always a reason why suddenly your AC is making strange noises. If it is an unknown sound, it could indicate a problem brewing in the AC.
The best course of action is to book an appointment for your local HVAC expert to come and check out things for you. The bottom line is that you do not ignore any abnormal sounds from your AC. Ignoring the problem will not make it go away; it will only compound the issue resulting in high repair costs. In the worst case scenario, it may kill your AC entirely.
In the heat of summers, the worst thing that could happen to you is an AC that does not work properly. Instead of relaxing is nice and cool air you find yourself bearing the brunt of warm air. This happens when the AC fan is running, but the compressor does not kick in. Considering how often your air conditioner runs, it isn’t surprising that something has gone wrong with the compressor. This does not translate to a death sentence for your AC. So don’t panic. Your AC compressor is not working, but the fan is running, so the situation is not too dire. Through the medium of this article, we shall help you understand why this could be happening.
AC Compressor Not Working But Fan Is Running
You may be wondering why the AC fan is running even when the compressor is not working. Often the problem is simple enough, and you can deal with it yourself. In some rare cases, you may require an HVAC technician to come and have a look at it.
1. Incorrect Thermostat Setting Or Faulty Thermostat – Somebody may have, by mistake, changed the thermostat settings. You expected the compressor to work to cool the room, but the thermostat read the room as already cool enough. So there was no need for the compressor to start. If that is the case, all you need to do is change the thermostat to the correct setting. If the thermostat is faulty, which your AC technician can tell you, the only option is to replace it.
2. Dirty Coil And Filters – Dirty condenser coils and air filters can put undue pressure on the compressor, causing it to overheat. At such times, the compressor shuts down automatically. If you fail to clean the air filters and the condenser coil your compressor may actually go belly up. Instead of waiting for that to happen, clean the condenser coils, and change the air filters, remove all obstructions and blockages in the vents so that air flows freely.
3. Unit Not Receiving Power – If you have a split AC, there is a possibility that the outside unit which houses the compressor is not getting power. The fan is working because the inside unit faces no such problem. For this, you need to have some knowledge about the electricals. You will have to examine the wiring that connects the two units. You also need to check the circuit breaker for a trip and also whether there is a blown fuse or not. If you are unable to do these things on your own, call an AC technician to check things out for you.
4. Capacitor And Relay Problems – Capacitor and relay are critical to supplying power to the compressor. A majority of the times these are what cause the compressor problems. Good news is that they happen to be cheap and so will not tax your pockets unnecessarily. However, replacing them is a little tricky, and so you may want a qualified technician to deal with them.
5. Dead Compressor – When little problems are left unattended, they blow out of proportions and cause major damage. One such damage that can be caused by an overheating unit and a faulty capacitor is a dead compressor. When the compressor is dead, your only option is to replace it with a new one as no repairs can be carried out. A compressor change should only be handled by an HVAC expert.
6. Mismatch Between Indoor And Outdoor Unit – In split AC you cannot just replace the complete unit (indoor or outdoor), on your whims and fancies, if there is a problem. The two units are matched to each other. If recently you have replaced either of your units, and the compressor is not working, it may indicate to the fact that the two units are not matched. This is an expensive mistake. You may want to consult your HVAC company for knowing your options.
7. A Decade Old Unit – Your AC may be really old and already past its useful, productive life. With age, internal components deteriorate due to wear and tear. AC compressor not working but fan is running, may happen to be one of the ways in which the problem manifests itself. If your unit is old, its best to buy a new one to avoid future problems.
What Happens When The AC Compressor Malfunctions
When there is an AC compressor failure, you may face one or more of these situations –
- Strange noises coming from the outdoor unit.
- Shaking in the outdoor unit when it starts.
- Compressor fails to start altogether.
- Warm air coming from the air conditioner.
- Your AC keeps tripping the circuit breaker.
Can AC Compressor Be Repaired
In some cases, the AC compressor can be repaired. However, this is one call which is best left to the experts in the field. Remember, the compressor is the very heart of your air conditioner. Sometimes a bad heart can be repaired, but at other times the only way to save the complete mechanism is through a heart transplant. Try to understand why your AC technician is advising you to replace the compressor instead of repairing it. If doubts persist, you can take the opinion of another technician from a different company.
Maintenance Can Solve Most Issues
Overlooking maintenance may seem to save you a few dollars, but the fact remains that it is necessary to keep your AC in good working condition. During maintenance itself, many things which damage the compressor get addressed. An expensive repair at a later on date or a relatively cheap annual maintenance, the choice is yours to make.
In The End
AC compressor not working but fan is running, this may cause you some discomfort and concern. But the best course of action is to get an HVAC expert to check the problem for you. Even if the issue is small, your AC would have got a complete checkup to prevent any more further concerns. Don’t wait for an issue to escalate, at the first sight of it book an appointment with an HVAC expert.
Every home either has a central air conditioner or a split AC. So a majority of us are not new to odors emanating from the air conditioning vents. But that does not mean you have to live with these smells and get used to them. Odors are maddening and can arise due to multiple reasons. Once you find its cause, you can accordingly take corrective action. Today, let us concentrate our efforts in finding out how to fix odor coming from air conditioning vents. Before we begin, let’s first try to understand a little more about these odors.
Why Does The AC Smell Bad?
A common illness that, surprisingly, a large number of air conditioners suffer from is the “Dirty Sock Syndrome”. This is no laughing matter. Imagine you come back home after a hard day of work and you are greeted with the repulsive dirt socks smell. Well! Wouldn’t that sour your mood? Dirty sock syndrome is when your AC gives out a foul moldy smell. This odor arises from the build-up of bacteria and mold on the evaporator coil.
Another odor coming from air conditioning vents could be that of heating or burning wires. This odor is quite distinctive, and it is caused by loose cables or a short-circuited board.
If there is a rotten egg smell coming from your AC, it could be caused by a dead animal decaying in your air duct. In winters, small animals may find their way into the vents and make a home. If they die in the same place, the AC carries that smell and throws it inside your house.
How To Fix Odor Coming From Air Conditioning Vents
As is clear from above, there are a number of reasons for the awful odor coming from your air conditioning vents. To fix the problem, there are several things which you could do.
1. Clean The AC – There are many parts of AC which you can clean yourself, like, the air filters and ducts. All you need is a brush, rag and a wet/dry vacuum cleaner with a long hose attachment. Cleaning the filters and ducts will ensure that there is no bacterial build-up. You can also see to it that there is no standing water in the drip pan and the drain line. Damp areas in the air conditioner propagate mold formation.
2. Install Duct Filters – Cleaning the duct filters every day is not possible. You can only do so once in a while. For all the other times, installing duct filter pads in the AC vents will help control the odor issue to a large extent. These filters are hypoallergic and are easily available at many home improvement stores.
3. Seasonal Maintenance – Through the course of seasonal maintenance, the AC is given a thorough cleaning and tuned up for maximum efficiency. This takes care of deep cleaning of the AC to kill bacteria and germs along with any other small animals who would have found their way into your HVAC system. It also takes care of loose nuts, bolts, and wires. These are tightened so that they do not cause sparking at a later on date. Ignoring seasonal maintenance to save a few dollars is not sensible.
4. Odor Control Methods – In some seasons, especially the monsoons, the moldy smell is perpetually present everywhere. This is mainly because everything becomes wet and promotes mold and mildew formation. Your AC may simply be picking up this odor and circulating within the house. So it is not necessary that the issue is in the AC. In the wet and damp season, you can look for artificial odor control methods. Burning an incense stick, switching on the air purifier, placing baking soda directly inside the air duct, placing potpourri of dried aromatic herbs strategically around the house are some ways to control the odor.
5. Call For Professional Help – Once you have done all that you can to control the odor and yet it persists, it’s time to call for some professional help. It is best to get help from HVAC experts because they can get into the nook and crannies of your HVAC system and clean and disinfect it top to bottom. Getting help from the experts is advisable when-
6. You find a dead animal or rodent inside your duct. Since it has started decaying, it could cause health hazards. So, thorough cleaning and disinfecting become a necessity.
7. You can see significant mold growth inside various parts of your AC.
8. Dust and debris have severely clogged the AC.
9. You suspect that there is a leakage in your ducts. This will need to be dealt with by professionals as your AC would have to be uncovered to fix all the leaks.
Whom To Hire For Professional Help
Whenever you are looking for someone to handle your air conditioner problems, keep in mind that there will be genuine companies as well as those who are looking for some easy cash. Always hire an HVAC company that can provide you with all the credentials. If in doubt, look up their reviews online. Most importantly get estimates from more than one company to make the best choice. When they claim there is a problem with the air conditioner ask for evidence. These few tips will assist you in choosing your HVAC expert correctly.
Odor coming from air conditioning vents may or may not be a big problem. The chances are that the former will hold true rather than the latter.

Air conditioners work day in and day out to keep our homes nice, cool and comfy. It is not unheard of for them to act up once in a while. They are machines after all, which will suffer wear and tear due to constant use. A common problem faced by many homeowners is that of Freon leak. But how will you come to know that your AC is leaking Freon? Usually, to confirm this analysis, you will need your AC technician to come and verify it. No matter what, never take Freon leak lightly because it will give rise to efficiency and health issues.
What Is Freon?
Freon is the refrigerant or coolant used in air conditioners to cool the air. Modern-day refrigerants like R-410A (Hydrofluorocarbons) are better than what was being produced earlier (Chlorofluorocarbons), but they are still not wholly environment-friendly.
Why Does Freon Leak Need To Be Taken Seriously?
No matter which class of Freon your AC contains, it is not entirely safe for both the environment and your health. They still result in global warming though not to the same extent. What is not safe for the environment is not safe for mankind as well. Other than that, refrigerant leak dramatically reduces the efficiency of the AC, thereby reducing the cooling effect and increasing the power consumption. Your room will now take longer to cool, and there will be a steep rise in your electricity bills.
Is Your AC Is Leaking Freon?
How to identify an AC leaking Freon? If you are not sure whether your AC is leaking Freon, look for one or more of the below symptoms.
1. Warm Air Coming From AC – The very first sign of a refrigerant leak is that your AC will start blowing warm air into the room even when you have set the temperature to be comfortably cool. This warm air is, in fact, a relative comparison because the air may seem warm in comparison to how cool it used to be earlier for the same temperature setting.
2. Loss In Cooling Efficiency – When there is a refrigerant leak, the room will take much longer to cool, and even then it will not be as expected. Typically, the refrigerant absorbs heat from the air and cools it down. In case of a leak, heat absorption is not adequate due to which the efficiency of the air conditioner falls.
3. Sounds Emanating From The Indoor Unit – Holes and cracks in the coil which hold the refrigerant often result in hissing and gurgling sounds. The bigger the crack, the louder the noise. However, every noise is not an indicator of a Freon leak. Your AC could be making noise due to some other problem as well.
4. Frozen Coils – When there is a drop in the refrigerant circulating in the AC, the coils inside are unable to absorb the heat from the air. In the absence of sufficient heat, the condensation freezes on the coils. At times, this frozen condensation melts and drips on to the floor causing wet spots and water puddles. Frozen coils may seem like a small issue, but if left untreated, it can escalate to compressor failure.
5. Steep Rise In Electricity Bills – As stated above, the time it takes to cool down a room increases in case of an AC leaking Freon. The longer it takes to cool the room, the more power the air conditioner consumes. There happens to be a direct relation between the two. This leads to the conclusion that your electricity bill is bound to increase. If you compare two bills, last years and current years, and see that there is an inconsistent increase in the current bill, it could be an indicator of your AC leaking Freon.
What To Do If You Suspect Refrigerant Leak?
A refrigerant leak should never be taken lightly because it could have detrimental effects on your health as well as those of your family members. It can cause nausea, dizziness, and trouble in breathing. If at any point you suspect that your AC is leaking Freon contact your local HVAC company immediately.
Fixing Refrigerant Leak
The above symptoms may be indicators of Freon leak but not always necessarily so. These symptoms could arise due to a number of other factors as well. Before jumping to any conclusions yourself, get advice from an HVAC expert. Based on their findings, you will either get a confirmation of what you suspect, or they could point you in the right direction.
Once you are sure “AC leaking Freon” is the culprit you need to decide whether refilling the refrigerant and repairing the point of leak is your chosen course of action. Ideally, if your AC is more than a decade old and uses R-22 refrigerant, the best course of action would be to buy a new AC. If your AC is new, you can go ahead with repairs on the coil so that there are no further leaks and top up the refrigerant to the recommended level.
Who Should Carry Out The Repairs
Your AC is an expensive piece of equipment and needs to be handled with care. It is recommended that you do not carry out any repairs on your own. This is basically to ensure that instead of mitigating the problem, you do not propagate it. Remember, professional help is just a call away. These professionals are not only qualified but also have the right equipment to resolve all your HVAC problems.
Finding out whether your AC is leaking Freon is not a big issue. But do get a certified professional to confirm your findings. It is mainly because what you think to be a refrigerant leak could also be something else.
