Methods of Cleaning Air Ducts: How Professionals Do It
An air duct cleaner will seal off the air ducts and use a special vacuum to put the entire heating and cooling system under negative pressure. While the system is under negative pressure, the air duct service provider will agitate the inside of the duct work with motorized brushes and other equipment. The brushes loosen any debris and contaminants in the duct work and the vacuum removes it without contaminating the rest of the home. Air duct cleaning is utilized in both residential and commercial buildings.
