There are two key components to HVAC air duct 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.
HVAC system cleaning is not a complex process, but each job is unique. 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.
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.
Air Duct Cleaning of New England (ADC) cleans more than just ducts. National Association of Duct Cleaning of America (NADCA) recommends that the entire HVAC system should be cleaned. Failure to clean all components of the system can result in recontamination of the entire system, thus minimizing the benefits of cleaning.
Just as you wouldn’t clean only half of your living room floor, you wouldn’t clean part of your HVAC system. Air Duct Cleaning of NE cleans the entire system, including the following components:
- Air ducts
- Crain pan
- Air plenum
- Blower motor and assembly
- Heat exchanger
- Air filter
- Air cleaner
What is air duct cleaning?
An air duct cleaning is the process of removing accumulated dirt, dust, debris, and other contaminants from the HVAC (heating, ventilation, and air conditioning) system’s ductwork. This can include the supply and return air ducts, registers, grilles, diffusers, and other components of the HVAC system.
Over time, dirt and debris can accumulate in the HVAC system, which can negatively impact indoor air quality and the efficiency of the HVAC system. Cleaning air ducts is important. An air duct cleaning can help to remove these contaminants and improve indoor air quality, as well as improve the performance and efficiency of the HVAC system.
Air duct cleaning can be performed by a professional HVAC technician using specialized equipment, such as high-powered vacuums and brushes, to clean the ductwork thoroughly. The frequency of air duct cleaning will depend on factors such as the age of the HVAC system, the level of use, and the indoor air quality in the building.
