What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Mansfield township, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

Construction in Mansfield township, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Achieving this standard in your blower door test in Mansfield township, NJ lowers utility bills and guarantees adherence to local code requirements.

Preparing for a Blower Door Test in Mansfield township, NJ

To ensure accuracy during blower door test in Mansfield township, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other 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. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Mansfield township, NJ efficiency standards.
