What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. 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 Jenkintown, PA identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Jenkintown, PA, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the PA climate.

What Is A Passing Blower Door Test Score?

In Jenkintown, PA, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. In most areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency. Achieving compliance in your blower door test in Jenkintown, PA helps improve energy efficiency and meet all local code mandates.

Why Do I Need A Blower Door Test?

Preparing for a Blower Door Test in Jenkintown, PA

When preparing for blower door test in Jenkintown, PA, we first switch off the home’s heating, cooling, and exhaust systems. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and 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. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Jenkintown, PA.
