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 frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Collingswood, NJ helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Collingswood, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

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. 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?

In Collingswood, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. Achieving this standard in your blower door test in Collingswood, NJ lowers utility bills and guarantees adherence to local code requirements.

Preparing for a Blower Door Test in Collingswood, NJ

Getting ready for blower door test in Collingswood, NJ involves turning off all heating, cooling, and exhaust ventilation systems. 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. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Collingswood, NJ energy code requirements.
