What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Washington township (Burlington), NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

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

To properly prepare for blower door test in Washington township (Burlington), NJ, the HVAC system and all bathroom and kitchen fans are turned off. 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. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected 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. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Washington township (Burlington), NJ energy code requirements.
