Indoor air quality is one concern that homeowners have when they decide to investigate air duct cleaning. In a typical six-room home, up to 40 pounds of dust is created annually through everyday living. Your heating and cooling systems are the lungs of your home. The system takes air in and breathes air out. Through normal occupation in a home, we generate a great deal of contaminants and air pollutants, such as dander, dust and chemicals. These contaminants are pulled into the HVAC system and re-circulated 5 to 7 times per day, on average. Over time, this re-circulation causes a build-up of contaminants in the duct work.
While dirty ducts don’t necessarily mean unhealthy air in your home, school or workplace, they may be contributing to larger health issues or harboring contaminants that could cause serious problems for people with respiratory health conditions, autoimmune disorders or some environmental allergies. According to the U.S. Department of Energy, 25% to 40% of the energy used for heating or cooling a home is wasted. Contaminants in the heating and cooling system cause it to work harder and shorten the life of your system. Although filters are used, the heating and cooling system still gets dirty through normal use. When an HVAC system is clean, it doesn’t have to work as hard to maintain the temperature you desire. As a result, less energy is used, leading to improved cost-effectiveness.
