This was the worst service possible. A bad bait & switch VALPAC ad "$65 for whole air duct cleaning package and no hidden charges". I was charged $250 for "duct cleaning: -which involves using a small compressed hose/ air and blowing the face of the vent ducts. A small vacuum was connecting to one of the other ducts. This did not accomplish anything other than blow more dust into the air. The company is DUCTMASTER Inc. DO NOT MAKE MY MISTAKE.
