What Is A Blower Door Test?

A blower door test is performed to identify the rate of air changes per hour, confirming your home receives a healthy exchange of fresh air. Excess air exchange can harm efficiency because each replacement of indoor air requires extra energy to heat or cool it again. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Audubon, 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?

To complete blower door test in Audubon, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

In Audubon, PA, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Meeting this benchmark in your blower door test in Audubon, PA reduces ongoing energy costs while ensuring local regulatory compliance.

Preparing for a Blower Door Test in Audubon, PA

To prepare a home for blower door test in Audubon, PA, we shut off the HVAC system and disable all exhaust fans. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Audubon, PA energy code requirements.

Blower Door Test for Contractors in Audubon, PA

Most professionally insulated homes undergoing blower door test in Audubon, PA can resolve small issues on-site during the contractor’s visit.
