Air duct cleaning is the cleaning of the various components of heating and cooling air systems, as well as the air ducts, themselves. These components include the supply and return air ducts, grilles, diffusers, registers, heat exchangers, coils, and condensation drain pans. If these components are not properly maintained, your ducts will become clogged. Clogged ducts can create moisture and evolve into a breeding ground for mold, blowing dangerous mold spores into your home’s air supply. Regular air duct cleaning eliminates this threat.
