Blower Door Test in Morgantown, PA

How Is A Blower Door Test Conducted?

For accurate blower door test in Morgantown, PA, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

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. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in PA conditions.
