How Is It Done?

A professional air duct cleaner will follow a specific cleaning process comprising two concurrent steps—agitation and collection. Agitation refers to the technician’s use of an agitation device, such as a compressed air nozzle, to break the particles loose from the surface of the system. While this is going on, the entire HVAC system is placed under continuous negative pressure—a vacuum, in other words—that removes fine particles from the system as the agitation causes them to become airborne.

By doing this, the technician ensures that these particles won’t re-enter your rooms once the system is turned back on. A reputable professional will use the correct equipment, take the required time to do the job right, be licensed, and not damage your system during the cleaning process.
