What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Southampton, PA, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under PA weather.

What Is A Passing Blower Door Test Score?

Residential buildings in Southampton, PA must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Reaching the target during your blower door test in Southampton, PA guarantees lower energy consumption and full code compliance.

Preparing for a Blower Door Test in Southampton, PA

Before conducting blower door test in Southampton, PA, we make sure all heating, cooling, and ventilation fans are switched off. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. After the home is depressurized, outdoor air pushes in more strongly, allowing leaks to become more noticeable. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. Our technicians bring chalk, spray foam, and weatherstripping supplies to handle visible air leakage issues directly with homeowners or contractors on-site. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Southampton, PA.
