What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Folsom, PA helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Folsom, PA, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. 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.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. 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?

Houses in Folsom, PA are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency. Reaching this target in your blower door test in Folsom, PA helps maintain lower energy bills and fulfills local code obligations.

Preparing for a Blower Door Test in Folsom, PA

For blower door test in Folsom, PA, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. We conduct a quick retest after sealing to verify that the desired blower door score has been achieved and that your home adheres to Folsom, PA energy efficiency codes.
