Blower Door Test in Hoboken, NJ

How Is A Blower Door Test Conducted?

To complete blower door test in Hoboken, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. 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.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.
