Too many air changes can negatively impact efficiency, as every replacement of indoor air demands additional heating or cooling energy. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Franklin township (Gloucester), NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. 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 indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

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

Before starting blower door test in Franklin township (Gloucester), NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. 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. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces 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 sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Franklin township (Gloucester), NJ.
