We offer sweeping, air washing, or both services through our negative vacuum system for your ductwork. While cleaning your ductwork, we are collecting the debris in our negative pressure HEPA vacuum. This allows us to remove dust, mold, pet dander, pet hair, sheetrock dust, skin cells, and other bacteria that can be found in cool damp areas, such as your duct work.
We also sanitize duct work to kill mold and stop the spread of bacteria in it’s tracks with the SaniJet system.
