Blower Door Test in Jackson township, NJ

How Is A Blower Door Test Conducted?

To conduct blower door test in Jackson township, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. 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.

What Is A Passing Blower Door Test Score?

Construction in Jackson township, NJ must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. In most areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency. Complying with this benchmark during a blower door test in Jackson township, NJ helps cut energy expenses and meet local building regulations.
