Blower Door Test in Hilltown, PA

Improve insulation performance and meet energy code requirements through thorough blower door test in Hilltown, PA. Our certified team helps homeowners, builders, and contractors locate air leaks, enhance indoor comfort, and meet all PA energy efficiency requirements.

What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Hilltown, PA makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Hilltown, PA, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. 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.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in PA weather.

What Is A Passing Blower Door Test Score?

Residential buildings in Hilltown, PA must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Meeting this level during your blower door test in Hilltown, PA supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Hilltown, PA

To prepare a home for blower door test in Hilltown, PA, we shut off the HVAC system and disable all exhaust fans. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond the thermal envelope. Once everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with Hilltown, PA building codes.
