What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in North Haledon, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately.
