Image for Top Signs It’s Time to Replace Your Air Conditioner Before Summer Hits

You might be wondering if its time to replace your ac. Summer is on its way, and for Floridians, that means time spent dwelling on what can sometimes seem like the threshold of an inferno. Your air conditioner is about to be the most essential appliance in your home. So, when is the right time for an air conditioner replacement?

Is your AC system aging? Inefficient? It might be time to replace it. Waiting means that you might experience failures on hot days, expensive emergency service calls, and high energy bills. HVAC vendors may have days or weeks-long wait lists for service. Here are some signs that you should get a new system before the mercury soars.

1. Your AC Is 10-15 Years Old

AC systems typically have a 10 to 15-year lifespan. If your unit is 10 or more years old, then even if it’s still working well, it’s likely outdated and inefficient. Upgrading now will help reduce your cooling costs significantly and reduce the risk of a potentially terminal breakdown in the middle of August.

2. Frequent Repairs Are Adding Up

Are you spending a lot of money on repairs? Occasional repairs are standard, but if you have your HVAC technician on speed dial, it’s likely time to consider a replacement. You’re going to end up spending more than the cost of a new system on service calls.

If your unit is unreliable, it’s time to bite the bullet and replace it.

3. Your Energy Bills Are Creeping Up

Cooling is a significant percentage of your electricity bill. If your bills are slowly creeping up, then something in your cooling system might not be working well. Take into account, of course, any increased usage and compare it to similar conditions in previous years.

A newer system will likely have a higher SEER (Seasonal Efficiency Energy Ratio) rating, delivering better performance and using less energy. You may see significant improvements.

4. Your Home Isn’t Cooling Evenly

Your bedroom is a sauna while you can practically leave perishable produce out on the kitchen counter. Or you seem to be adjusting the thermostat constantly. This is a sign that your system isn’t maintaining consistent airflow.

This might be caused by wear and tear on an older system. However, it could also indicate that you or the home’s previous owner tried to save money by installing a system that isn’t up to the size of your home. Both are good reasons to replace your AC.

5. You Hear Strange Noises Or Smell Unusual Odors

Now is the time to do an air conditioner replacement when you hear strange noises or smell unusual odors. Broken HVAC systems can produce banging, rattling, or squealing noises or musty smells. Don’t forget to check the outdoor unit for odd noises as well. All of this indicates a serious issue that, at the very least, needs to be repaired. Recurring noises can indicate significant mechanical failures and may be cheaper to replace. A nasty smell is often mold growth, especially typical in Florida’s humid climate, which can impact your and your family’s health.

6. Humidity Issues Are Increasing

Your HVAC also controls humidity, and in Florida, it’s often true that it is the humidity, not the temperature, that is making you miserable. If your home still feels sticky or muggy with the AC going full blast, your system is not effectively removing moisture from the air. Some people resort to a dehumidifier but look at your AC system before you do so. Modern systems are better at controlling humidity without extra help.

7. Your System Still Uses R-22 Refrigerant

This is also known as Freon and has been phased out for years. It’s now hard to find, expensive, and dangerous to the environment. If you have one of these ancient systems, you should upgrade immediately. Not only will you save money, but you will also help the environment and your health with current, eco-friendly refrigerants.

It’s also a sign that your system is not up to modern efficiency standards.

I have had pretty good service from Aztil for the last 4 years as a service contract customer. I called them when my AC stopped working and they sent a tech who replaced a 45/7.5 capacitor in about 15 minutes. He then gave me an invoice and estimate for $375.00. I questioned him on what work he did and show me the part he replaced. He showed me the capacitor and said $375 was the cost to replace it. If you look up the part it only cost $25, even with a service call charge there is no way it should have cost me $375... I am beyond pissed and have tried to call Aztil to speak with someone about it but no one is calling me back. I hope this is not your experience just thought I would share mine

Follow up on this review.... Jack the service manager reached out and apologized for the mistake on the charges and issued a refund. Mistakes happen it's how the company handles them that makes a difference. I am glad they resolved this issue relatively quickly.
Response from the owner:Hello John, Thank you for taking time to provide feedback about your experience with our company.

On July 17th my air conditioning stopped working properly (it was set to 75 but was running at 82) and customer service scheduled a quick date for repair. Michael King was the technician they sent and he was very professional, friendly and explained what was being done. He was very thorough and made sure everything was resolved before he left. I would recommend Michael King for any A/C repair.
The a/c is again running great.

Juan came to our condo within two hours of me calling the company with a two week water leak that other companies could not fix within the past two weeks. He was therefore probably close to an hour to diagnose the problem, found what he thought was the problem, called me because I am out of town and had friends in the apartment to let them in, and he explained everything extremely professionally and calmly and told me thatafter the weekend since today is Friday they would probably try to get the part that’s needed which was a new ACP pan perhaps and did diagnose other problems. So far, we are extremely happy thank you. Kudos to Juan.
Response from the owner:Hi Claudia, thank you for your kind words! We're so glad to hear that Juan did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.

I wanted to commend Dana Dussualt for his hard work at rectifying a substantial issue that I had with my HVAC system. It did require multiple visits but he stuck with it and figured out the issue and did get it resolved. Dana spent hours in the attic in the middle of summer working on getting this fixed. He is both a very hard worker and a pleasant individual. Dana is a credit to your company. In addition, the office staff worked with me in getting these repairs done by insuring we would get service on the date promised. Having no air conditioning in the summer is not a great experience. I have been an Aztil customer for many years.
Response from the owner:Hi Lyle, thank you for your kind words! We're so glad to hear that Dana did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
