Blower Door Test in Wanaque, NJ

How Is A Blower Door Test Conducted?

When conducting blower door test in Wanaque, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.
