What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in Concordville, PA helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Concordville, PA, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in PA.

What Is A Passing Blower Door Test Score?

In Concordville, PA, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Meeting this benchmark in your blower door test in Concordville, PA reduces ongoing energy costs while ensuring local regulatory compliance.

Preparing for a Blower Door Test in Concordville, PA

Before starting blower door test in Concordville, PA, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other 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. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Concordville, PA energy efficiency codes.
