The Process of Air Duct Cleaning

Air duct cleaning is only a “blanket term.” In fact, the entire HVAC system should be cleaned. Not cleaning the entire system can result in re-contamination, thus reducing the benefits of cleaning. You wouldn’t clean only half of your kitchen, you also would not want to clean only part of your HVAC system. The NADCA recommends cleaning the entire HVAC system, including the following components:


The Process of Air Duct Cleaning

  • air ducts

  • coils

  • registers

  • air plenum

  • blower motor and assembly

  • heat exchanger

  • air filter

Breaking Contaminants Loose

Properly cleaning HVAC systems requires the removal of unwanted contaminants. This could include, dust, pet and human dander, pollen, mold, rodents and their feces and remains, and bacteria. The process begins with using an agitation device such as brushes, air whips and compressed air nozzles called “skipper balls.” These devices are designed to loosen the contaminants from the air ducts. Agitation can also be achieved through hand-brushing or vacuuming.

Collection of Contaminants

During cleaning, the entire HVAC system is placed under continuous negative pressure (a very large and strong vacuum) to prevent the spread of contaminants. This negative pressure sucks the particles being scrubbed off of your ducts. Doing so, prevents particles from being released back into the home 

System Access

HVAC system cleaning is not a complex process, but each job is unique. Access to the interior of the ducts can be through existing openings. Such as supply diffusers, return grills, duct end caps and existing service openings. HVAC technicians may need to cut access holes in the ductwork. Creating these openings requires craftsmanship and professional skills. 

Equipment Requirements

There is a variety of equipment available to HVAC cleaning professionals. Both a truck-mounted and portable vacuum can be used to clean the system to the NADCA Standard. Amber’s Air Duct Cleaning uses two of the strongest, portable air duct cleaning machines to get the job done. Therefore, using two machines at once allows for a strong negative air pressure. By doing so, this leaves little to no dust remaining in your ducts after the process.

Antimicrobial Chemicals

Antimicrobial chemicals can be applied to your HVAC system after a cleaning. These include sanitizers, disinfectants and deodorizers. This helps control unwanted odors and gives the house a fresh scent. The EPA provides a list of certified disinfectants.
