Air Tightness Test


What is a blower door test?

Blower test is a way to determine the air tightness of your home and to identify air leaks that can cause drafts and higher energy use. This test begins by depressurizing the building. While the building is under depressurization, a home walkthrough is done to identify common areas of air infiltration; your advisor will perform a complete check of your home’s insulation, looking for gaps that may affect energy performance. A blower door test is included in the EnerGuide home evaluation or can be provided as a stand-alone service.
