What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering efficiency. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Warren, 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?

For blower door test in Warren, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

What Is A Passing Blower Door Test Score?

In Warren, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Meeting this requirement during your blower door test in Warren, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Preparing for a Blower Door Test in Warren, NJ

To prepare for blower door test in Warren, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. 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. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect 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. After completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Warren, NJ.
