Indoor air quality is typically a major concern for homeowners when they decide to investigate air duct cleaning. A home's heating and cooling system acts as a building's lungs as the system works to take air in and exhaust air out of a building.
Through normal daily activities in a home, people generate a great deal of contaminants and air pollutants, such as dander, dust, pollen and chemicals. According to the National Air Duct Cleaners Association, up to 40 pounds of dust is created annually through everyday living in a typical six-room home. This same dust may contain mold, lead and even asbestos if these materials are present in a home and have become airborne.
