Forty pounds. That's how much dust the EPA says the average home collects in a year. Much of that dust is made up of dead human skin cells, the glitter from Elton John's glasses, and other irritants. That's why the licensed, insured, and bonded technicians at US Duct Cleaners make interior air quality their main focus. Using tools that extend into HVAC systems' nethermost regions, the team sweeps out age-old dust, allergens, pollen, and debris. They demonstrate their commitment to quality work by backing up each of their services with a firm guarantee on parts and labor.
