What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Fort Washington, PA detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Fort Washington, PA, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. 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 Fort Washington, PA, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes.

Preparing for a Blower Door Test in Fort Washington, PA

We start the process of blower door test in Fort Washington, PA by ensuring all heating, air conditioning, and exhaust systems are turned off. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. When depressurization is complete, outside air flows in swiftly, allowing easy detection of leakage spots. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in Fort Washington, PA.
