Blower Door Test in Wyncote, PA

When conducting blower door test in Wyncote, PA, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in PA.
