What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Upper township, NJ, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. 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 Upper township, NJ

To prepare for blower door test in Upper township, NJ, we start by turning off the heating and cooling system, along with all bathroom fans 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. 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. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Upper township, NJ energy code requirements.
