What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Gloucester City, NJ 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?

When conducting blower door test in Gloucester City, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.

What Is A Passing Blower Door Test Score?

In Gloucester City, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Satisfying this requirement in your blower door test in Gloucester City, NJ helps optimize energy use and ensures you meet local building standards.

Preparing for a Blower Door Test in Gloucester City, NJ

For blower door test in Gloucester City, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces 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. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Gloucester City, NJ.
