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. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Piscataway, NJ identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Piscataway, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

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. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

What Is A Passing Blower Door Test Score?

Properties in Piscataway, NJ must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally.

Preparing for a Blower Door Test in Piscataway, NJ

Before starting blower door test in Piscataway, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. Next, we conduct a quick walkthrough of the home, confirming that all exterior doors and windows are securely closed — including those to unfinished basements, garages, or any area outside the thermal envelope. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Piscataway, NJ.
