Blower Door Test in Kintnersville, PA

How Is A Blower Door Test Conducted?

For blower door test in Kintnersville, PA, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under PA conditions.
