The Best Ways to Clean Air Ducts

What You Need to Know About Air Duct Cleaning

It isn't just the air ducts that need cleaning; the entire HVAC system must be cleaned. If the system is not cleaned properly, the benefits of the cleaning will be reduced. Cleaning the entire HVAC system is the best way to ensure that it is operating at peak efficiency. It is also important to clean the following components: Paraphrase: It is not advisable to clean only half of your living room floor. Therefore, you should also clean your entire HVAC system, which consists of the following components:


Breaking contaminants loose and collecting contaminants are the key components of HVAC air duct cleaning.


Removing Contaminants

An agitation device is used to loosen contaminants from the surfaces of the heating and air conditioning system so they can be removed. One or more brushes, air whips, or “skipper balls” are used to remove the sources of contamination. Hand-brushing or contact vacuuming can also achieve agitation.


A collection of contaminants

To prevent the spread of contaminants, the entire HVAC system is placed under continuous negative pressure (a vacuum) during cleaning. This negative pressure also extracts the loosened contaminants, which are removed from your home. The fine particles are removed from the system as they become airborne, ensuring that these particles are not released into your living space when the system is turned on after air duct cleaning.


Access to the system.

The procedure for maintaining an AC system is not difficult, however, each job is unique. Any available access points, such as supply diffusers, return grills, duct end caps, and service openings, should be used to enter ducts. Cleaning tools may require cutting holes into the ductwork in order to reach inside. The creation of these service openings, and their subsequent closure, requires specialized craftsmanship and skills.


You need the following equipment to perform this job: lawnmowers, leaf blowers, weed-eaters, hedge trimmers, hedge clippers, weed-whackers, and leaf rakes. There is a lot of equipment available to HVAC duct cleaning professionals to stop the spread of contaminants and clean to the NADCA Standards both truck-mounted and portable vacuums can be used.


Antimicrobial Chemicals Ingested

Sanitizers, disinfectants, and deodorizers can be applied to nonporous surfaces in HVAC systems to address microbial contamination and help control odors. Only chemicals registered with the United States Environmental Protection Agency (EPA) can be used. These chemicals should only be considered after mechanical surface cleaning has been completed and if the need for such treatment has been determined. For more information, see the NADCA White Paper Chemical Applications in HVAC Systems.
