Duct Cleaning We use a system called Ram Air. It uses powerful jets of air and vacuum to blast the dirt free and remove it to a hepa grade system. Most duct systems are very intricate as far as twists and turns go, which makes this method of cleaning superb. The Ram Air hose can easily get much father down the vents so that we can clean them from end to end. We remove all vents covers including cold air returns and properly clean them all. Something that sets this system apart is the fact that the homeowner is able to actually see the dirt as it is being removed. No magic duct cleaning here, you can actually see what we are removing.
