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. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Mainland, PA helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Mainland, PA, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. One main exterior door is identified, and an adjustable aluminum frame with a fabric panel is securely attached. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in PA climates.

What Is A Passing Blower Door Test Score?

In Mainland, PA, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. By meeting this standard in your blower door test in Mainland, PA, you can enjoy lower utility bills and peace of mind with code compliance.

Preparing for a Blower Door Test in Mainland, PA

Preparation for blower door test in Mainland, PA begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Mainland, PA.
