What is the Americlean duct cleaning methodology?
First, an access opening is created in the plenum, or in the main duct line next to the furnace. Then our highly trained experienced technicians connect the hose from a HEPA filtered high velocity vacuum to the access opening next to the furnace. Each register on the wall, floor, and ceiling is carefully removed and cleaned using a hand held HEPA filtered vacuum. (The EPA and NADCA contend that it is impossible to clean a duct system without removing all the registers). Vent openings are temporarily sealed off to eliminate the threat of dust in the home and to concentrate the vacuum’s negative air pressure. An electric rotary brush is used to dislodge the contaminants accumulated on the inner duct surface. (An EPA report, based upon scientific data, bluntly states, ” . . brushing is necessary to effectively clean the (duct) surfaces.” EPA-600/R-97-137. Yet many companies do not use brushes in their process.) An air-washing device is inserted to push the remaining debris toward the vacu
