The most effective way to clean air ducts is to use "source removal" techniques. This process is the highest standard in the industry and is the only method endorsed by the National Air Duct Cleaners Association, NADCA. Using The Air Medic's state-of-the-art truck-mounted vacuum, your system is placed under negative pressure. While the vacuum draws air through the system, various tools are inserted into the return and supply register boots to dislodge contaminants and debris. The powerful vacuum pulls the contaminants out of the air ducts, removing them from the system and your home with no mess left behind. The technician will also hand-detail clean each of your registers. The final steps are to clean the plenum, furnace, heat exchanger, evaporator coil, condensate drain pan, and the blower housing, motor & wheel.
