What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Washington township (Gloucester), NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As the fan removes air, outside air naturally flows inside through leaks, joints, and other gaps. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

Preparing for a Blower Door Test in Washington township (Gloucester), NJ

Getting ready for blower door test in Washington township (Gloucester), NJ involves turning off all heating, cooling, and exhaust ventilation systems. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. Once leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Washington township (Gloucester), NJ.
