Breaking Contaminants Loose: Effective HVAC system cleaning requires removing contamination sources. Removal begins with using one or more agitation devices that loosen contaminants from the HVAC system surfaces. Agitation devices include brushes, air whips, and compressed air nozzles or “skipper balls.” Agitation is also achievable through hand-brushing and contact vacuuming.
Contaminant Collection: The entire HVAC system receives continuous negative pressure (vacuum) to prevent contaminants from spreading during cleaning. The constant negative pressure removes fine particles as they become airborne, preventing their release into the living space. This negative pressure also extracts and collects all loosened contaminants, removing them from the property.
System Access: 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 ductwork to reach inside with various cleaning tools. The creation of these service openings, and their subsequent closure, requires craftsmanship and professional skills.
Antimicrobial Chemicals: Sanitizers, disinfectants, and deodorizers can be applied to non-porous surfaces in HVAC systems to address microbial contamination and help control odors. We use chemicals registered with the United States Environmental Protection Agency (EPA) and only after performing surface cleaning if the treatment is necessary.
