Blower Door Test in Upper Black Eddy, PA

How Is A Blower Door Test Conducted?

To complete blower door test in Upper Black Eddy, PA, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in PA.

What Is A Passing Blower Door Test Score?

In Upper Black Eddy, PA, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Passing this requirement during a blower door test in Upper Black Eddy, PA keeps your home efficient and aligned with local building code standards.
