What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Wycombe, PA detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Wycombe, PA is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in PA.

What Is A Passing Blower Door Test Score?

In Wycombe, PA, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Meeting this requirement during your blower door test in Wycombe, PA helps reduce energy costs while keeping your home compliant with local building codes.

Preparing for a Blower Door Test in Wycombe, PA

Preparation for blower door test in Wycombe, PA includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve 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 infiltration from outdoors increases, allowing faster and more accurate leak detection. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Wycombe, PA.
