Why ducts need cleaning
Filters stop a lot, but not all, of the dust and debris moving through your heating and cooling system. It collects inside the ducts and gets blown back into the rooms you live in.
How negative-air cleaning works
A negative air system pulls air, dust and debris out of the ductwork, so loosened dirt leaves the system instead of blowing into your home.
