What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Harrison township, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

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. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

Construction in Harrison township, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close any gaps connecting conditioned and unconditioned spaces, such as those leading to basements, attics, or crawl spaces.

Preparing for a Blower Door Test in Harrison township, NJ

To ensure accuracy during blower door test in Harrison township, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. 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. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Harrison township, NJ.
