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. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Clementon borough, NJ detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Clementon borough, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

Preparing for a Blower Door Test in Clementon borough, NJ

As part of preparing for blower door test in Clementon borough, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond 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. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Clementon borough, NJ energy standards.
