The blower door test is a diagnostic tool used by our energy advisors to measure a home’s airtightness. During this test, a powerful fan is fitted into an exterior doorframe and temporarily seals all other openings, such as windows and vents. The fan then either depressurizes or pressurizes the house, causing air to flow through any gaps, cracks, or openings. The primary goal of this test is to detect air leaks, which helps reduce energy consumption and enhance home comfort. Additionally, the blower door test provides data on air changes per hour (ACH) and the equivalent leakage surface (ELS), allowing comparison with other homes built during the same era.
