Blower Door Test in Toughkenamon, PA

How Is A Blower Door Test Conducted?

For blower door test in Toughkenamon, PA, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in PA.

What Is A Passing Blower Door Test Score?

In Toughkenamon, PA, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Passing this requirement during a blower door test in Toughkenamon, PA keeps your home efficient and aligned with local building code standards.
