Blower Door Test in Dublin, PA

How Is A Blower Door Test Conducted?

When conducting blower door test in Dublin, PA, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in PA.
