What is a Blower Door Test?

An infiltrometer, also known as a blower door, is a fan set up in an exterior doorway with a computer attached to it. The blower door will measure how much air leaks within the home. All homes leak air, but some homes leak more than others. Depending on the size of the home and occupants, depends on how much the home should leak. Any extra leakage is just a waste of energy and money.
