A blower door test is a specialized diagnostic procedure used in construction and energy auditing to measure how airtight a building is. The test uses a calibrated fan mounted in an exterior doorway to either pressurize or depressurize the home. This creates a pressure difference between the inside and outside, allowing air to flow through any unsealed gaps or cracks. Detecting these leaks helps identify where energy loss occurs, ensuring more efficient heating, cooling, and ventilation.
