What Is A Blower Door Test?

A blower door test is performed to identify the rate of air changes per hour, confirming your home receives a healthy exchange of fresh air. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Maple Shade, NJ 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 blower door test in Maple Shade, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

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. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Residential buildings in Maple Shade, NJ 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.

Preparing for a Blower Door Test in Maple Shade, NJ

Preparation for blower door test in Maple Shade, NJ begins with switching off the HVAC system, as well as any bathroom and kitchen exhaust fans. 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 ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. 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. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Maple Shade, NJ energy standards.
