What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in South Plainfield borough, NJ helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in South Plainfield borough, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. A precise nanometer instrument allows us to compare the pressure generated by the fan to that within the house. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

Homes throughout South Plainfield borough, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators.

Preparing for a Blower Door Test in South Plainfield borough, NJ

Preparation for blower door test in South Plainfield borough, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. 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, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with South Plainfield borough, NJ efficiency standards.
