Blower Door Test in Lyndell, PA

How Is A Blower Door Test Conducted?

When performing blower door test in Lyndell, PA, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. A calibrated fan is used to depressurize the home through the frame to 50 Pascals, representing the same pressure as a 20 mph wind.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in PA conditions.

What Is A Passing Blower Door Test Score?

Residential buildings in Lyndell, PA must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Meeting this requirement during your blower door test in Lyndell, PA helps reduce energy costs while keeping your home compliant with local building codes.
