We create comfortable homes by fixing leaky ones
See how a blower door test is performed to test for air leakage within a home.
One of the quickest and most affordable energy-saving projects is to seal cracks and openings around your house, but first you have to find the leaks. Some air leakage is obvious because you can feel it, such as a draft under an exterior door. Other leaks are less obvious.
Air leakage can be contributing to your uncomfortable home and high energy bills. Before making efficiency upgrades, we recommend having a blower door test performed during your home energy audit to determine exactly how your home is using and losing energy.

How a blower door test works
A blower door test 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 cracks and openings. While the fan is running, a technician will inspect each room for air leaks. A pressure gauge measures the pressure differences inside and outside the home and an airflow manometer measures the airflow. The data provided by the blower door test allows the technician to quantify the amount of air leakage in your home, as well as find any unsealed openings following air sealing work.
