Blower Door Testing in Eagleville, TX

How Is A Blower Door Test Conducted?

In Blower Door Testing in Eagleville, PA, TX, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. 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. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. 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 Texas climate.
