Blower Door Test in Springfield township, NJ

How Is A Blower Door Test Conducted?

When performing blower door test in Springfield township, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. 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 Springfield township, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Reaching the target during your blower door test in Springfield township, NJ guarantees lower energy consumption and full code compliance.
