We use Rotobrush aiR+ professional air duct cleaning equipment (rotary brush and vacuum) and believe very strongly that this is the best equipment to clean the air ducts in your home. Our equipment features a camera system so that if you would like, you can see what we are doing as we are doing it. The Rotobrush aiR+ is designed specifically to handle the soft, flexible ducts in homes in the South. We are able to clean air ducts by inserting the rotating brush into the duct. With the brush rotating at 450 rpm, it loosens any debris that may be stuck inside. While the brush is scrubbing the walls, the vacuum sucks up the debris, leaving your air ducts clean.
On the other hand there are many more air duct cleaning companies that will properly clean the air system and air ducts and use commercial negative air duct cleaning vacuums with at least 2,000 CFMs of vacuum power and utilize proper agitating tools to move the contaminates within the duct work to be captured with HEPA filters and contained by the air duct cleaning vacuum equipment.
