A home energy audit helps home owners determine where their house is losing energy and how such issues can be corrected in order to make the home more energy efficient. When we do an energy audit on your home we use a blower door tester. This tool uses a fan that blows air into or out of the building to create an air pressure difference between the interior and outside. The pressure difference forces air through all holes and penetrations in the exterior. By measuring the airflow through the fan and its effect on the inside air pressure the blower door tester measures the overall air tightness of your home.
We do this test before and after the work is completed to show the results of our air sealing and how we improved your home and comfort. The blower door tester also estimates natural infiltration rates in your home. Then we do a thermal inspection throughout the house.
