Blower Door Test in Springfield, PA

How Is A Blower Door Test Conducted?

For blower door test in Springfield, PA, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. 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.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under PA weather.

What Is A Passing Blower Door Test Score?
