What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. When there are too many air leaks, drafts and discomfort can occur, along with moisture problems such as mold and condensation. A blower door test in Lumberton, 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?

To complete blower door test in Lumberton, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

Homes in Lumberton, NJ are typically required to follow the 2015 International Energy Conservation Code (IECC) or the most recent version adopted locally. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Achieving this standard in your blower door test in Lumberton, NJ lowers utility bills and guarantees adherence to local code requirements.

Preparing for a Blower Door Test in Lumberton, NJ

To properly prepare for blower door test in Lumberton, NJ, the HVAC system and all bathroom and kitchen fans are turned off. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside the thermal envelope. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. When the home reaches depressurization, outside air seeps in rapidly, helping identify leaks with greater accuracy. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Lumberton, NJ.
