What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Irvington, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

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 depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to 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.
