Blower Door Test in Holicong, PA

How Is A Blower Door Test Conducted?

To complete blower door test in Holicong, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in PA weather.

What Is A Passing Blower Door Test Score?

In most areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency.
