How It Works and When To Do It: AC Duct Cleaning

Image for How It Works and When To Do It: AC Duct Cleaning

One of the worst experiences for Southeast Florida residents is an HVAC unit that sputters to a stop in mid-August. Keeping up with routine maintenance, such as AC duct cleaning, helps eliminate unwelcome surprises.

Why Your AC Ducts Matter

While a downed AC unit at the height of Palm Beach County’s summer is an unfortunate scenario, the fact is, your HVAC system works hard to keep your home comfortable year-round.

In addition to cooling, our area’s hot and humid climate requires HVAC systems to control humidity and maintain healthy indoor air quality.

Pollutants like mold, pet hair, and dust gradually build up inside ductwork over time, negatively impacting indoor air quality. The buildup causes your system to work harder, ultimately contributing to higher energy bills and prematurely worn-out components.

Scheduling professional duct cleaning is an effective way to ensure your system continues to run at peak performance.

How AC Duct Cleaning Works

Aztil Air’s highly trained technicians employ a six-step method to remove contaminants from your home’s HVAC ductwork effectively. Our specialists utilize state-of-the-art technology to maintain healthy air circulation and energy efficiency.

  1. Inspection – One of our professionals will initially inspect the system’s ductwork, often with a camera, to determine the level of buildup. We also assess the system’s overall condition, checking for blockages, leaks, or damage.
  2. Preparation – Before cleaning, the technician seals off registers and vents to prevent debris from spreading.
  3. Powerful Vacuum System – Once thoroughly assessed and prepared, we connect a high-powered vacuum—often truck-mounted—to your duct system, which creates negative pressure that effectively pulls out dust and contaminants.
  4. Agitation Tools – We combine specialized brushes, air whips, and powerful compressed air tools to loosen and completely suction out stubborn debris from duct surfaces.
  5. Cleaning Components – Aztil Air’s technicians may also inspect and clean related parts like registers, grills, fans, and coils to improve airflow and efficiency.
  6. Final Inspection – The technician conducts a final inspection once cleaning is completed to confirm your system is clean and ready for optimal performance.

When to Schedule AC Duct Cleaning

Experts generally recommend cleaning ducts every 3 to 5 years. However, more frequent cleanings may be necessary if you experience the following concerns.

  • Unexplained Dust Buildup: Surfaces require frequent dusting.
  • Poor Airflow: Rooms feel stuffy, or their temperature is uneven.
  • Rising Energy Bills: Restricted airflow could be causing your system to work harder.
  • Allergy or Respiratory Issues: Sneezing, coughing, or asthma flare-ups occur more frequently indoors.
  • Visible Mold or Odors: You notice any visible signs of mold growth or musty odors inside ducts or on vents.
  • Post-Renovation: Dust and debris can quickly clog ducts if you’ve recently completed a construction or renovation project.

4 Important Benefits of Clean AC Ducts

Maintaining clean HVAC ducts is essential, and here are a few reasons.

  1. Better Indoor Air Quality – Less dust, allergens, and irritants in your home allow you to breathe easier.
  2. Improved Efficiency – Your HVAC system runs smoothly with free-flowing air.
  3. Longer System Life – Regular AC duct cleaning can help your HVAC reduce the need to replace components.
  4. Lower Energy Costs – Less strain on your system means reduced energy use.

Final Thoughts

AC duct cleaning is an investment in your comfort, your health, and your HVAC system’s performance. If it’s been years since your last cleaning—or you’ve never had one—consider scheduling an inspection with Aztil Air. The difference in your home’s air quality and comfort can be remarkable.

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
