Residential Duct Cleaning
From manufactured homes to site-constructed homes, AAA Heating and Cooling’s technicians are fully equipped to meet your air quality needs and exceed your customer service expectations. We are NADCA (National AirDuct Cleaners Association) certified and trained, and we are concerned about you and your indoor air quality.
Duct cleaning should occur every three to five years on average, but each home and family is different. The frequency of cleaning depends on several factors, not the least of which is the preference of the home owner. Some consider it important to have more frequent cleanings due to pets that shed high amounts of hair and dander, smokers in the household, water contamination, or the health of residents with allergies or asthma. Duct cleaning should be done after any home renovations or remodeling and prior to occupying a new home.
Our Duct Cleaning Process
- We start with a home visit. Something as important as the quality of the air you breathe is worth an onsite survey and system review. We have highly-trained service advisors who will visit your home at no cost and discuss your needs and concerns. Our advisors will take the time to show you your system and how dirty it is, and they will explain to you how our procedure works.
- We provide a clear blueprint of the process. After completing the onsite survey and system review, the service advisor will leave with you a checklist/proposal detailing what is to be accomplished and at what price. There are no surprises in our bids. When our cleaning crew arrives, they will have the same checklist/proposal and will be glad to show you each step completed
What You Can Expect
- It’s No Small Task. Duct cleaning is a very involved process. Technicians need access to all areas of the home, and it can take up to a full day to complete the task.
- You’ll Need to Plan Ahead. Duct cleaning cannot be done on the same day as any other service. Other equipment that needs work will need to be tended to on a different day. Also, it can disturb pets and others in the home, so some pre-planning may be necessary to make any needed arrangements.
Research by the U.S. EPA has demonstrated that HVAC system cleaning may allow systems to run more efficiently by removing debris from sensitive mechanical components. Clean, efficient systems are less likely to breakdown, have a longer life span, and generally operate more effectively than dirty systems. Help yourself and your family to “Breathe Easier” today.

Duct Cleaning Checklist
Did the service provider obtain access to and clean the entire heating and cooling system, including duct work and all components (drain pans, humidifiers, coils, and fans)?
Has the service provider adequately demonstrated that duct work and plenums are clean? (Plenum is a space in which supply or return air is mixed or moves; can be duct, joist space, attic and crawl spaces, or wall cavity.)
Is the heat exchange surface visibly clean?
Are the blower blades clean and free of oil and debris?
Is the blower compartment free of visible dust and debris?
Are both sides of the cooling coil visibly clean?
If you point a flash light into the cooling coil, does the light shine through to the other side? It should if the coil is clean.
Are the coil fins straight and evenly spaced (as opposed to being bent over and smashed together)?
Is the coil drain pan completely clean and draining properly?
Is the return air plenum free of visible dust and debris?
Do filters fit properly and are they the proper efficiency as recommended by the HVAC system manufacturer?
Is the supply air plenum (directly down-stream of the air handling unit) free of moisture stains and contaminants?
Are interior ductwork surfaces free of visible debris? (Select several sites at random in both the return and supply sides of the system.)
Is all the fiberglass material in good condition (i.e., free of tears and abrasions; well adhered to underlying materials)?
Access Doors and Covers
Are newly installed access doors in sheet metal ducts attached with more than just duct tape (i.e., screws, rivets, mastic)?
With the system running, is air leakage through access doors or covers very slight or non-existent?
Have all the registers, grilles, and diffusers been firmly re-attached to the walls, floors, and/or ceilings?
Are the registers, grilles, and diffusers visibly clean?
Does the system function properly after cleaning?
If you answered “No” to any of the above questions, this may indicate a problem with the job. Speak to your contractor regarding these issues and ask him to make corrections to his/her work such that you can answer all the questions “Yes.”
