The most effective way to clean air ducts is to use “source removal” techniques. This process is the highest standard in the industry and the only method endorsed by the National Air Duct Cleaners Association, NADCA. This requires a cleaning contractor to place the system under negative pressure, through the use of a specialized powerful vacuum.
Our air duct truck (the only of its kind in Southern Illinois) places the WHOLE duct system under negative pressure at one time. While the vacuum draws air through the system, various tools are inserted in the return and supply register boots to dislodge contaminants and debris and remove them from the system with no mess left behind.
