Should You Have the Air Ducts in Your Home Cleaned?
Duct cleaning generally refers to the cleaning of various heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing, and the air handling unit housing. If not properly installed, maintained, and operated, these components may become contaminated with particles of dust, pollen or other debris. If moisture is present, the potential for microbiological growth (e.g., mold) is increased and spores from such growth may be released into the home's living space. This document is designed to aid homeowners in deciding whether or not to have their ducts cleaned, how to choose a cleaning service provider and what to expect of them, and also provides tips on how to prevent duct contamination.
