What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Blue Bell, PA helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

During blower door test in Blue Bell, PA, exterior openings are closed securely, and interior doors are left open to maintain even air circulation across the house. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. Once the frame is in place, a calibrated fan is used to bring the home’s pressure down to 50 Pascals — about the same as a 20 mph wind on the structure.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air 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?

Properties in Blue Bell, PA must meet the efficiency guidelines of the 2015 International Energy Conservation Code (IECC) or the latest version adopted locally. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Complying with this benchmark during a blower door test in Blue Bell, PA helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in Blue Bell, PA

Getting ready for blower door test in Blue Bell, PA involves turning off all heating, cooling, and exhaust ventilation systems. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond 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 depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with Blue Bell, PA efficiency standards.
