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. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Monroe township, NJ helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Monroe township, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel 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.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

Preparing for a Blower Door Test in Monroe township, NJ

We start the process of blower door test in Monroe township, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. 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 sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Monroe township, NJ.
