Blower Door Test in Croydon, PA

Verify your home’s airtightness and meet energy-efficiency standards with a professional blower door test in Croydon, PA. Our skilled technicians help homeowners, builders, and contractors find air leaks, increase comfort, and comply with PA energy standards.

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. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. 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 Croydon, PA identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in Croydon, PA, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. An adjustable aluminum frame and sturdy fabric panel are installed in one central exterior door to prepare for testing. The technician mounts a calibrated fan to the frame to depressurize the house to 50 Pascals, roughly matching a 20 mph wind effect.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. 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 Croydon, PA, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. 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 Croydon, PA keeps your home efficient and aligned with local building code standards.

Preparing for a Blower Door Test in Croydon, PA

Getting ready for blower door test in Croydon, PA involves turning off all heating, cooling, and exhaust ventilation systems. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. 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 Croydon, PA.
