Blower Door Test in Immaculata, PA

How Is A Blower Door Test Conducted?

To conduct blower door test in Immaculata, PA, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in PA climates.

What Is A Passing Blower Door Test Score?
