Blower Door Test in Berkeley Heights, NJ

How Is A Blower Door Test Conducted?

In preparation for blower door test in Berkeley Heights, NJ, all exterior entry points are sealed, and interior doors are left open to allow consistent air circulation. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. 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.
