Are you concerned about the energy efficiency of your home? If so, a blower door test can help. A blower door test is a diagnostic tool used to measure the air leakage rate of a building. It is done by creating a negative pressure inside the home, and then measuring how much air flows through the cracks and gaps in the building envelope. The results of the test are expressed as an air change rate (ACH50), which is the number of times the entire volume of air in the home will be exchanged with outside air in one hour.

A blower door test is a valuable tool for homeowners in Pennsylvania. The state has a humid climate, which can lead to mold and mildew growth if there is too much air leakage. Blower door testing can help to identify areas of air leakage, so that they can be sealed up to improve the home’s energy efficiency and indoor air quality.
