Assess your home’s air sealing and energy standards with trusted blower door test in Abington, PA. Our experts help homeowners, builders, and contractors pinpoint air leaks, improve efficiency, and comply with PA building energy standards.

What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Abington, PA enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Abington, PA, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in PA.

What Is A Passing Blower Door Test Score?

Residential buildings in Abington, PA must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Meeting this benchmark in your blower door test in Abington, PA reduces ongoing energy costs while ensuring local regulatory compliance.

Preparing for a Blower Door Test in Abington, PA

To ensure accuracy during blower door test in Abington, PA, we begin by switching off the HVAC system and all exhaust fans in the home. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond the thermal envelope. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Abington, PA.
