Dirty air ducts aren’t harmless.

U.S. Environmental Protection Agency (EPA) studies have found that indoor air maybe two to five times—and occasionally more than 100 times—more polluted than outdoor air. Indoor air pollutants can cause health problems. Considering that the average American spends 90% of their time indoors, improving indoor air quality is vital.*


One way to improve a home’s indoor air quality is to have the air ducts cleaned.

Air Duct Cleaning Services

Indoor air pollutants are pulled into the HVAC system and re-circulated an average of 5 to 7 times per day. Over time, this recirculation causes a build-up of pollutants in the duct work. **


In addition to improving air quality, air duct cleaning also results in energy savings. Pollutants collect and clog the heat exchanger, evaporation coil and duct in the HVAC system making it work harder to heat and cool the home. Removing pollutants allows the HVAC system to work more efficiently.

According to the standards provided by the National Air Duct Cleaners Association (NADCA), it is recommended that you have your HVAC ductwork inspected every two years.
