What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Bridgeton, NJ helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Bridgeton, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. 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 air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. 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?

Construction in Bridgeton, 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. Reaching the target during your blower door test in Bridgeton, NJ guarantees lower energy consumption and full code compliance.

Preparing for a Blower Door Test in Bridgeton, NJ

When preparing for blower door test in Bridgeton, NJ, we first switch off the home’s heating, cooling, and exhaust systems. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside the thermal envelope. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Bridgeton, NJ.
