What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Folsom borough, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

Preparing for a Blower Door Test in Folsom borough, NJ

To prepare a home for blower door test in Folsom borough, NJ, we shut off the HVAC system and disable all exhaust fans. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Folsom borough, NJ energy efficiency codes.
