How Does a Blower Door Test Work?
Blower door testing helps locate air leaks in a house and is typically performed before and after air sealing. A blower door uses a special fan that’s mounted in the frame of an exterior door to pull air out of the house, lowering the air pressure inside. The pressure difference between the air inside and outside the house forces the outside air in through all the cracks and openings. Measurements are taken during the test to determine the air tightness of the home.
