Professional Blower Door Testing in the Minneapolis, St. Paul and Surrounding Areas

What Is a Blower Door Test?

During a blower door test, a technician will use a large fan to remove air from the house. As air exits, the air pressure in the house decreases, and outside air is pulled inside through leaks. The technician can then determine where the air is coming in and out of your home.

Why Test Building Tightness?

The tighter your home is, the less air will pass in and out, which makes it easier to maintain the temperature and air quality of your home. A blower door test identifies the weak spots in your house so that you can add more insulation or repair small holes.
