What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Wantage, NJ helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Wantage, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. 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. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. These measurements yield air changes per hour (ACH), showing how airtight and energy-efficient the property is in NJ.

What Is A Passing Blower Door Test Score?

In Wantage, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction.

When your blower door test in Wantage, NJmeets this requirement, you benefit from reduced energy bills and code compliance.

Preparing for a Blower Door Test in Wantage, NJ

To properly prepare for blower door test in Wantage, NJ, the HVAC system and all bathroom and kitchen fans are turned off. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. 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 chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Wantage, NJ.
