The Best Procedure:
A technician connects the power vacuum to the home's air handler with an 8" hose. Then he inserts the high-velocity air sweeper into the ductwork. He controls it with a hose connected to the truck's air compressor which supplies up to 200 pounds of air pressure.
Duct Doctor's patented vacuum truck is the industry's most powerful. With the vacuum and cleaning aparatus, all contaminants are removed from the ductwork and stored outside in the truck's debris collector for safe disposal.
