What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Deptford township, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

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. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

Homes in Deptford township, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Meeting this benchmark in your blower door test in Deptford township, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

Preparing for a Blower Door Test in Deptford township, NJ

To ensure accuracy during blower door test in Deptford township, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. 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. 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. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Deptford township, NJ energy efficiency codes.
