Blower Door Testing in Fairview Village, TX

How Is A Blower Door Test Conducted?

Before Blower Door Testing in Fairview Village, PA, TX, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. 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 pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in Texas conditions.

What Is A Passing Blower Door Test Score?

In Fairview Village, PA, TX, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency. When your blower door test in Fairview Village, PA, TX meets this requirement, you benefit from reduced energy bills and code compliance.
