Blower Door Test in Forked River, NJ

How Is A Blower Door Test Conducted?

Before blower door test in Forked River, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

What Is A Passing Blower Door Test Score?
