Blower Door Test in Sea Isle City, NJ

How Is A Blower Door Test Conducted?

When performing blower door test in Sea Isle City, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.
