What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Erwinna, PA, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. 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.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. 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.

What Is A Passing Blower Door Test Score?

Residential buildings in Erwinna, PA must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. 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. Achieving compliance in your blower door test in Erwinna, PA helps improve energy efficiency and meet all local code mandates.

Preparing for a Blower Door Test in Erwinna, PA

To prepare for blower door test in Erwinna, PA, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Erwinna, PA building codes.
