How Duct Cleaning Works

August 12, 2012 Professional Services, Water Damage Repair Comments Off on How Duct Cleaning Works

Why should you clean your air ducts?

Studies have shown that indoor air can be 2 to 5 times more polluted than outside air. Most disposable filters only remove about 10% of these pollutants – allowing 90% to enter the air system, even during the construction of a new home.
The pollutants – dust, pollen, mold spores, & animal dander – collect in the air conditioner and duct surfaces, just as they do on the furniture and floor surfaces. The furniture and floor are cleaned regularly, but the duct surfaces are hidden from view and can only be reached by specialized duct cleaning equipment.

These pollutants can migrate out into the room again, or become a food source for mold and bacteria, which can thrive in this dark comfortable environment from high humidity or moisture from the air conditioner or humidifiers. Biological growth can release mold spores or toxins into the air system.
