Blower Door Test in Pine Valley, NJ

How Is A Blower Door Test Conducted?

When performing blower door test in Pine Valley, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.
