What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Paramus, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.
