Air duct cleaning is the process of cleaning the accumulated dirt and debris from a forced air heating and cooling system. This involves cleaning the duct work, grilles, registers, coils and all other parts of the system.
The buildup of dirt, dust, dander and mold can be removed from a heating and cooling system by loosening debris with brushes or agitation devices and then vacuuming with high-powered, truck-mounted or portable vacuums. Some contractors even follow up with chemicals to clean the duct work thoroughly. A clean heating and cooling system can improve indoor air quality and result in energy savings due to increased operating efficiency.
