What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. 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 Perkasie, PA detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Perkasie, PA, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the PA climate.

What Is A Passing Blower Door Test Score?

Construction in Perkasie, PA must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. When your blower door test in Perkasie, PAmeets this requirement, you benefit from reduced energy bills and code compliance.

Use insulation featuring the proper R-value and verify complete, gap-free coverage across the building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Seal all joints and gaps that connect conditioned and unconditioned areas such as basements, attics, and crawl spaces.
Many cities provide compliance checklists through their building departments — see the Philadelphia version here.

Preparing for a Blower Door Test in Perkasie, PA

To prepare a home for blower door test in Perkasie, PA, we shut off the HVAC system and disable all exhaust fans. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside 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. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Perkasie, PA.
