What Is a Blower Door Test?
A blower door test is not an overly complicated procedure, but it does involve a lot of special equipment that only trained professionals possess, as well as the skills required to use that equipment properly. Essentially, a blower door test requires that a blower fan be temporarily installed in the door of your home. Your windows and all other doors should be closed tightly, so that your home is as sealed up as it can be. The blower fan then pulls air out of your home depressurizing it. As it does so, air from outside will be pulled into your home via air leaks, seeking to balance the pressure. This will help your technician to pinpoint weak spots in your home’s thermal envelope.
Why Schedule a Blower Door Test?
All homes require a certain amount of natural ventilation, and no home is, or should be, completely airtight. If you have excessive air leaks in your home, though, your energy efficiency, indoor air quality, and the success with which you heat and cool your home will be jeopardized. With the information collected by your technician following the blower door test, you can get a handle on any such issues so that you can go about having them resolved by a qualified party.
