Duct Cleaning: An Essential Service or Unnecessary Expense?

Image for Duct Cleaning: An Essential Service or Unnecessary Expense?

The purpose of ducts is to be invisible. Hidden behind walls and ceilings, they carry cool air to vents in every room of the house. But just like the inside of your AC needs cleaning now and then, so do your ducts. While it may not seem important compared to the components of your house that you can see, that dust building up on every surface and your out-of-season allergies could result in years-long buildup inside the ducts themselves. Learn more about whether duct cleaning is a necessary or unnecessary expense.

What Is Duct Cleaning?

Duct cleaning removes built-up dust, debris, allergens, and microbiology inside your home’s ducts. Ducts deliver air throughout your house so whatever builds up in the ducts winds up in the air in every room. If you can see lint on the vents or open a vent to see a carpet inside the duct, it’s time for duct cleaning.

Duct cleaning is accomplished using a giant high-powered vacuum, brushes, and sanitization techniques to pull all those unwanted contaminants out of your ducts and drastically increase your home’s air quality.

The Case for Duct Cleaning

Why is periodic duct cleaning a necessary expense? There are several profound benefits, especially if you have noticed problems like off-season allergies, unpleasant odors, respiratory problems, excessive dust, or HVAC energy efficiency loss.

  • Improved Indoor Air Quality: Cleaning your ducts can stop the harm caused by ducts that are blowing dust, pollen, and other harmful particles that can be blown into each room. You may immediately notice that the air and surfaces are less dusty, that chronic respiratory problems decrease, and you stop experiencing out-of-season allergies.
  • Enhanced System Efficiency: Air flows more easily through clean ducts, which are smooth and open compared to ducts clogged with dust. Your system will work more efficiently and your AC may be able to use less electricity to maintain temperature stability. Duct cleaning can even help lengthen your HVAC lifespan by removing some strain.
  • Odor Elimination: The dust carpet inside a duct can trap odors from pets, cleaning agents, tobacco smoke, and even food preparation. You may notice these lingering smells are gone when your ducts are clean, resulting in a fresher-smelling home.
  • Mold and Mildew Prevention: Humidity and plant growth are rampant in Florida, leading to a higher risk of mold growth. Humid dust carpets in your ducts can become a home for mold and mildew. Duct cleaning can prevent mold growth, protecting your home and your health.
  • Pest Prevention: Sometimes, pests may even find their way into your ducts. Their droppings, debris, and activity can cause long-term damage. Duct cleaning can remove and prevent infestations, and alert you to any needed repairs.

When Duct Cleaning May Be Unnecessary

Duct cleaning is something homes need after the dust has built up for several years. It is also needed more frequently when an HVAC system is poorly filtered. But this also means there are situations where you may not need duct cleaning.

  • Newer Homes With Clean Ducts: If your ducts are recently installed, perhaps because your home was recently built, dust won’t have had time to build up yet, and cleaning is not necessary until after a few years.
  • No Visible Signs of Dust or Debris: Open a vent and check the duct inside. If you see a carpet of dust or smell animal or mildew, then cleaning can be beneficial. You don’t need a cleaning if you don’t see any dust, debris, or odors.
  • Well-Maintained HVAC Systems: Ducts build up dust that travels from the HVAC units into the ductwork. However, if you frequently change filters and have your HVAC systems cleaned, your ducts will stay clean for longer.
  • No Allergy or Respiratory Issues: If you haven’t noticed excessive dust, indoor allergy symptoms, strange smells, or respiratory issues, duct cleaning may not be a priority.

How Often Should You Clean Your Ducts?

Duct cleaning is typically necessary every 3 to 5 years after there has been some time for dust and debris to build up. If you have pets or live in a dusty area – or have recently renovated – you may need more frequent duct cleanings. You may need duct cleaning less often if you are attentive to your HVAC filters and maintenance cleanings.

Choosing a Reputable Duct Cleaning Service

If you have determined that your home needs duct cleaning, how do you choose a good provider?

  • Have Proper Certification: Your team should be certified by the National Air Duct Cleaners Association (NADCA).
  • Use Professional Equipment: Your provider should use professional-grade equipment with a practiced routine that does not damage your home.
  • Provide Transparent Pricing: Seek a transparent and itemized quote. Avoid companies that offer prices that seem too good to be true. Quality duct cleaning requires time and expertise, which should be reflected in the pricing.
  • Offer References: Check for positive company reviews online to see what other customers have to say.

Air Duct Cleaning on Your Schedule

Is duct cleaning a necessary expense? It depends on your home’s air quality and the benefits that duct cleaning can offer you. Check your ducts to see if they have built up a carpeted layer of dust and debris. Duct cleaning can also help resolve off-season allergies, give mold no place to hide, and ease long-term respiratory problems. But if your air, home, and ducts are clean, wait a few years and check again.

Niko, great service! Thank you!
Niko was personable and knowledgeable
Antonio was great and he was personable and I really do like him the next time that I have a visit from you guys it will be from him and I almost decided not to use you guys no more because of the other two gentlemen that came they were young boys, and they did not do things properly, but Antonio was very very good and I really liked himHe was very professional so thank you very much for letting Antonio come and giving yourself a second chance have a blessed day.
Nicholas (I think that’s his name) was very thorough and knowledgeable. I’m going to take his recommendation for a UV light. Please send him back to install when I order it. He furthers my trust in Aztil.
Response from the owner:Thank you for your review, Al Levy. We're so glad you had a positive experience with our appliance repair services!
Very happy with the service provided by Niko
Technician Lazaro Powery arrived much sooner than I expected. He looked professional, and his behavior matched his appearance. I really enjoyed our brief personal chat. I always ask people I deal with if their company treats its employees well, as it matters to me. I was happy to hear that he enjoys his employment with Aztil.

His professionalism and attitude well matched his positive comments. I'm not surprised as I find Aztil to be excellent people to deal with in all requests and transactions. Lazaro sets a good example for Aztil. Thanks for sending him. When he asked, I signed another one-year service contract
I had 3 terrific technicians Paul Gross who found the problem fixed it but also found a leak so I had 2 technicians Jordan and Hero come and do the duct work I was so impressed by all 3 of them their knowledge professional and the enjoyment in doing the work for their clients I give all 3 of 10 gold stars😀
AZTIL is a real COOL company and Jackie my rep @Aztil responds ASAP when I get HOT on the phone. Seriously Jackie’s the nicest person. I don’t want to leave anyone out but Juan the technician goes above and beyond trying to solve my HVAC problems.
Alex was very thorough and knowledgeable.
Tino was professional and friendly. Thank you for a great service over the years.
I have used aztill air conditioning service for over 15 years. They have always been prompt and have always done a great job. I recently would like to praise Dana who came to my home today and his boss Jack for the great price. My wife and I feel blessed to have found them. They have been reasonable in their prices and the technician are right on point. Thank you Aztill Air. 😁😃
This was my first experience with Aztil as a new homeowner. I purchased a service agreement which I thought was reasonably priced. My first scheduled maintenance was this past week by Michael King .He was extremely professional, knowledgeable and very kind in explaining everything I needed to know. He made a great suggestion in which I followed through with. He’s an asset to this very professional company. Thank you Aztil and Jonathan for a job well done!
Mike came by for an A/C maintenance check up. He came on time and was very friendly and professional.
Response from the owner:Hi Larry, thank you for taking the time to leave us such a positive review about Fabio. We are delighted to hear that he was on time and provided excellent service. We appreciate your feedback and are glad that you had a good experience. Thanks again!
Excellent service very knowledgeable Niko send him hereafter
Tino was exceptional in sevicing both of my AC its. I renewed my contract with Aztil and I look forward in having Tino service me again Thanks for great service
I had to have my air conditioning HVAC system replaced. I bought RHEEMS from them nine years ago or just shy of nine years ago and I had to have the whole thing replaced. It had a leak. The pressure was down 3 pounds and to pay $475 only because I had a contract with them otherwise it would’ve been 675 to check for the leak.. I decided to replace it cause I knew it was around the corner anyhow. They installed it the next day I couldn’t have been more pleased. It was effortless. It took them a while because we had some rain on and off and they couldn’t be on the roof, but they came at 9:30 and they left at 3 o’clock. I thought they did very well. They left my house clean as a button just exactly the way they found it. They were very polite and did everything that they were supposed to do in a very neat and tidy and timely manner.
Jorge and David were the installers today. They were timely, professional, mannerly, exceptionally clean and efficient. And Sabrina in their office went beyond in responding as the cost of new units today is sticker shock!
Nico is absolutely amazing! Very informative and an excellent technician! This is the second time we’ve had him and he’s great
Response from the owner:Hi Kathy, Thank you so much for your wonderful review! We're glad to hear that you had an excellent experience with our service. We pride ourselves on our knowledgeable staff, and it's great to know that Ramon was able to provide you with such great service. We appreciate your feedback and hope to see you again soon!
After 40 hours without A/C in August we were saved by Rafael. He was polite, professional and courteous. He is an asset to the company. On another note, the scheduling system used for after hours is quite poor and needs to be looked into. Thank goodness Jackie called us and attempted to remedy the situation.
Naraldo Bunsie did an excellent job installing my new Trane A/C! Thanks !
Michael was very knowledgeable and efficient in providing service for us today. We’d love for him to come again
Your service techs and general service has improved since the corporate take over. Raphael Curci was efficient and kept us u[p to date on the progress of the installation. The person I'd like to call out as exemplary was Nico who guided us through the process and went out of his way to help us through this time. Ultimately the air handler was faulty and it took several visits to repair it. Meanwhile the handler leaked water all over the garage ceiling ruining it and causing damage to my model trains beneath. In addition the last tech broke my cable power supply which he had no business touching. I had to call Xfinity to come as an emergency for which they charged me $150.00. I will also be sending Aztil a bill for the repair of my ceiling and any damage done to my model trains.
Dana just finished a service call. He was very professional and explained to me what he was doing and gave me tips for the future. I have been an Aztil customer for many years and people like Dana keep me coming back.
Response from the owner:Hi Don, thank you for your kind words! We're so glad to hear that Angel did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
Michael was efficient and thorough. I am very pleased with this service.
Response from the owner:Thank you
Juan was fantastic!
Michael was great, he called in advance arrived on time, very professional and knowledgeable, and got the job done in a timely manner, highly recommend.
Michael provided excellent service on unclogging our drain line and explaining what options we have to prevent it getting clogged in the future.
Naraldo was was a competent and efficient skilled worker..
Doesn't talk much but gets the job done quickly.

Replaced and rewired our new water heater in a very short time.

Left everything clean and Sparkling..

Would have him return anytime for the next project that might pop-up.
Response from the owner:Hi Erlene, thank you for your kind words! We're so glad to hear that Rafael did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
Dana Dussault, the technician that came to fix my AC and installed a new compressor was so efficient and courteous and is an asset to Aztil. I was very happy with the work.
Nico and Adrian were great. Cleaned my ac and found an oil leak. Very personable.
Response from the owner:Hi Ilene, thank you for your kind words! We're so glad to hear that Niko and Adrian did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.
Rico was friendly and very competent & efficient
Response from the owner:Hi Shanti, thank you for your kind words about Ricardo and Aztil. We are so glad to hear that you had a great experience with us. We will make sure to pass along your positive feedback to Ricardo. Thank you for choosing Aztil!
Dana came on a Saturday in the pouring rain. Totally professional and knew what was wrong right away. Great job guys!
Dana was efficient and effective and answered all my questions. Top notch
I had a new central AC installed by Aztil today. Both of the techs, Jorge and David, were professional and friendly. I used Aztil because I have used them for service for over 10 years and have been very satisfied. I can recommend them for service and installations.
Tino was great. Answered all our questions and took his time to explain everything
They came quickly and Lazaro was very professional.
Lazaro Powery was fabulous!! He knew exactly what to do. He was very kind and I would definitely ask for him if I need any other issues with Aztel. You are lucky to have him with your company
Ramon came to fix my AC the day that it stopped working. He was pleasant, knowledgeable, and worked quickly. I highly recommend him and this company!
Aztil responded promptly to my ac problem. They were very professional and thorough. I recommend them highly.
Tino did a great job. He explained what our system needs and how much it would cost. We had someone else from Aztil here a few weeks ago and they did not take the time to diagnose our problem.
I recommend Aztil Air everything was done to perfection
