What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Clementon, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior 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 Clementon, NJ

Preparation for blower door test in Clementon, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces outside the thermal envelope. Once everything is closed off, we set up the blower door fan on a centrally located exterior door and depressurize the interior to 50 Pascals to assess air leakage accurately. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. 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. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Clementon, NJ.
