Find and fix air leaks while improving performance through reliable blower door test in Lenni, PA. Our experts help homeowners, builders, and contractors pinpoint air leaks, improve efficiency, and comply with PA building energy standards.

What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. 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 Lenni, 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?

To complete blower door test in Lenni, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. 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 creates negative pressure, outside air infiltrates the home through gaps and small openings. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in PA.

What Is A Passing Blower Door Test Score?

In Lenni, PA, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Passing this requirement during a blower door test in Lenni, PA keeps your home efficient and aligned with local building code standards.

Preparing for a Blower Door Test in Lenni, PA

When preparing for blower door test in Lenni, PA, we first switch off the home’s heating, cooling, and exhaust systems. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. When the home reaches negative pressure, outside air infiltrates through openings, making leaks visible. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Lenni, PA energy standards.
