Air Duct Cleaning/ Duct Cleaning

Author: Better Business Bureau

Heating, ventilation, and air conditioning (HVAC) systems have been shown to act as a collection source for a variety of contaminates, such as mold, fungi, bacteria and very small particles of dust, that have the potential to affect health. Research by the U.S. Environmental Protection Agency has demonstrated that HVAC system cleaning may allow systems to run more efficiently by removing debris from sensitive mechanical components. Consumers should be aware of the air duct cleaning companies that make claims about the health benefits of duct cleaning. The U.S. Environmental Protection Agency has found no such proof. Consumers should be aware that some air duct cleaning services will offer other services such as carpet cleaning or the elimination of mold in the house. If the consumer does not agree to the additional service, the company may only give the ducts a cursory cleaning before moving on to the next house. Before you decide that your air ducts need to be cleaned, remove air vents and shine a flashlight into the ductwork. Have your ducts cleaned only if they contain visible mold buildup or have debris coming out of air vents. After the ducts have been cleaned, insist on a thorough visual inspection. All components of the HVAC system should be free from visible dust and debris. Before servicing you may wish to contact The National Air Duct Cleaners Association (NADCA) a non-profit association that provides information on reliable air duct cleaning companies. NADCA provides pre- and post- cleaning checklists to insure that the total system cleaning is performed. For more information visit or call (202)737-2926.
