What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Mansfield township (Burlington), NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

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

Preparation for blower door test in Mansfield township (Burlington), NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside the thermal envelope. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Mansfield township (Burlington), NJ efficiency codes.
