Blower Door Test in Alpine, NJ

How Is A Blower Door Test Conducted?

When performing blower door test in Alpine, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. 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.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. 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.
