Blower door testing is a way to test the “leakiness” of your home.
As part of this process, we place a blower door into the frame of an exterior door. The blower door has a is a powerful fan mounted to it which pulls air out of the house, lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings. We will inspect the house with a smoke stick to pinpoint potentially hidden air leaks (making it much easier to address them when the time comes to get to work). By depressurizing your home and measuring the rate at which air infiltrates through imperfections in the building envelope, we’re able to assess how much energy (and money) is escaping through air leaks and how much you’re likely to save by fixing those leaks.
We also offer blower door testing as an isolated service to test the effectiveness of improvements that have been made to a home, and to provide homeowners and contractors with a roadmap to further improve a home’s efficiency moving forward.
In addition to being a critical component of a whole house energy audit, blower door testing is required for many green building and energy efficient building standards nationwide.
