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