What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. 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 Teaneck, 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 carry out blower door test in Teaneck, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As the fan expels air, the resulting pressure draws outdoor air in through hidden leaks and unsealed joints. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

In Teaneck, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance.

Preparing for a Blower Door Test in Teaneck, NJ

As part of preparing for blower door test in Teaneck, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned spaces outside 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 the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. After the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Teaneck, NJ energy code requirements.
