What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Runnemede, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Runnemede, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

Preparing for a Blower Door Test in Runnemede, NJ

Preparation for blower door test in Runnemede, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Runnemede, NJ energy standards.
