What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Ottsville, PA, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. 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.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal 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?

In Ottsville, PA, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Passing this requirement during a blower door test in Ottsville, PA keeps your home efficient and aligned with local building code standards.

Preparing for a Blower Door Test in Ottsville, PA

Getting ready for blower door test in Ottsville, PA involves turning off all heating, cooling, and exhaust ventilation systems. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Ottsville, PA.
