Local Knowledge About Blower Door Infiltration Analysis

Energy auditors and contractors often use a blower door to see how much air leaks through windows, doors, and other problem places in your house. The blower door is a large partition that blocks the front door of your house. A powerful fan in the blower door draws the air out of your house and causes a strong draft wherever the air is leaking in. This can help the contractor locate and seal the air leaks. Blower door treatment is often one of the most cost effective energy improvements that you can make to your home regardless of its age.
