What You Need to Know About Air Duct Cleaning

Darren Kincaid - Friday, June 28, 2019
Central Plumbing and Heating, Inc - Chesapeake, VA

Air duct cleaning is a misnomer. In actuality, the entire HVAC system must be cleaned and maintained. Failure to clean all components of the system can result in re-contamination of the entire system, thus minimizing the benefits of cleaning. Just as you wouldn’t clean only half of your living room floor, you also would not want to clean only part of your HVAC system. We recommend cleaning the entire HVAC system, including the following components:

  • air ducts
  • coils
  • drain pan
  • registers
  • grills
  • air plenum
  • blower motor and assembly
  • heat exchanger
  • air filter
  • air cleaner

There are two key components to HVAC cleaning: breaking contaminants loose, and collection of contaminants.

Breaking Contaminants Loose

Properly cleaning HVAC systems requires removing the sources of contamination. Source removal begins with the use of one or more agitation devices designed to loosen contaminants from the surfaces within the heating and air conditioning system. Examples of agitation devices include: brushes, air whips and compressed air nozzles or “skipper balls.” Agitation can also be achieved through hand-brushing or contact vacuuming.

Collection of Contaminants

During cleaning, the entire HVAC system is placed under continuous negative pressure (a vacuum) to prevent the spread of contaminants. Continuous negative pressure allows very fine particles to be removed from the system as they become airborne, ensuring that these particles are not released into the living space when the system is turned on after cleaning. This negative pressure also serves to extract the loosened contaminants, which are collected and removed from your home.

System Access

HVAC system cleaning is unique to each and every system. Where possible, access to duct interiors should be made through existing openings such as supply diffusers, return grills, duct end caps and existing service openings. Cleaning technicians may need to cut access holes in the duct work in order to reach inside with various cleaning tools. Creation of these service openings, and their subsequent closure, requires craftsmanship and professional skills.

Equipment Requirements

There is a wide variety of equipment available to HVAC cleaning professionals. Both truck-mounted and portable vacuums can be used to stop the spread of contaminants and get the system cleaned.

Antimicrobial Chemicals

Antimicrobial chemicals include sanitizers, disinfectants and deodorizers that 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 products should only be considered after mechanical surface cleaning has been performed and if the need for such treatment has been deemed necessary.
