Blower Door Test in Blooming Glen, PA

How Is A Blower Door Test Conducted?

For accurate blower door test in Blooming Glen, PA, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. 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. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in PA conditions.
