Duct cleaning is a maintenance job that an HVAC professional performs on an air conditioning system to remove any potential air pollutants and improve air quality. Poor air quality can lead to allergies, illness or the introduction of mold or other bacteria into a home or workspace.
Professional duct cleaning includes more than cleaning just the duct work in an HVAC system. It includes cleaning or treating all the parts of the air distribution system including vents, registers, and components of the air handler and the evaporator. In a contaminated HVAC system, it is important to have each possible part cleaned or treated to improve air quality. Just cleaning the ducts of a contaminated system and not addressing any other components can lead to recontamination.
