What is a Blower Door Test? A Blower Door test determines the airtightness of a home, often a New Construction home. The blower door itself is a type of fan that goes over one of your home’s exterior doors. The fan will suck out air from the house, bringing down the pressure as it does. The changes in air pressure cause the outdoor air to pass through any openings in the home. If yours is an uncalibrated blower door test, then the extent of your test results will be to reveal that your home has leaks. With a calibrated blower door test, the auditor can determine the quality of any prior air sealing as well as just how much air is leaking.
