Blower Door Test in Keansburg, NJ

How Is A Blower Door Test Conducted?

When performing blower door test in Keansburg, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. 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 the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.
