Air infiltration can account for 30 – 40 percent of your heating and cooling bills! Air leakage wastes energy and makes your home uncomfortable by allowing exterior air, humidity, dust, moisture, and pests inside. The blower door is a precise fan system with which we can test the leakiness of your home. Essentially, we suck the air out of the house and see where outside air is rushing in to replace it. With this test, we can increase the efficiency of heating and cooling systems, save you money, enhance indoor air quality, and dampen your impact on the environment.
