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. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Lyndell, PA assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

While performing blower door test in Lyndell, PA, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. 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 nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the PA environment.

What Is A Passing Blower Door Test Score?

Homes throughout Lyndell, PA are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Passing this requirement during a blower door test in Lyndell, PA keeps your home efficient and aligned with local building code standards.

Preparing for a Blower Door Test in Lyndell, PA

Preparation for blower door test in Lyndell, PA includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. 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 Lyndell, PA.
