How Does Air Duct Cleaning Work? First, we start by running a vacuum hose from our truck mounted power vac system directly to your home or commercial building's furnace. In doing this we essentially turn your entire HVAC duct-work into a vacuum. We then go around to each and every one of your vents and return air registers with an internal duct cleaning device. This device uses brushes to loosen anything that may be stuck to the walls of your air ducts. All of these contaminants are then pulled directly out of your house and into our truck mounted vacuum so that no dust or dirt is left in your system. This is the best and cleanest way to service your home's ducts. It is estimates by the U.S. Consumer Product Safety Commission there were 15,600 fires, 20 deaths, 370 injuries, and $75.4 million in property damage all attributed to dryer fires. Failure to clean is the leading cause of dryer fires. Don't let this happen to your home. The average U.S. Home can save almost 30% in clothes drying costs by cleaning and maintaining dryer ductwork, as well. In addition to dryer vents, many homes and condominiums use air ducts as a part of their cooling and heating systems. Clean ducts are essential to better air quality and lower utility bills.. hvac air duct cleaning and dryer vent cleaning and chimney cleaning
