A blower door is a powerful fan that we will mount in the frame of one of your exterior doors. The purpose of the use of the fan is to pull air out of your home, which will lower the pressure inside, allowing the outside air pressure to flow through any unsealed cracks and openings that exist in your home. Our trained specialist will walk through your home with a smoke pencil that will allow them to pinpoint your troublesome areas.
We use a FLIR Infrared Imager that will take thermographic scans of your home which measure surface temperatures by using infrared video. Using this test, in conjunction with our blower door testing, will help identify air leaks by showing up as black streaks on the infrared imager. Using an infrared imager can also help detect roof leaks because wet insulation conducts heat faster than dry insulation.
