Blower Door Test: Professional energy auditors use blower door tests to help determine a home's airtightness. A blower door is a powerful fan that mounts to the frame of an exterior door. The fan pulls air out Blower Doorof the house, lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings. This test determines the air infiltration rate of a structure.
