What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in Waterford township, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.

What Is A Passing Blower Door Test Score?

In Waterford township, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Achieving this standard in your blower door test in Waterford township, NJ lowers utility bills and guarantees adherence to local code requirements.

Preparing for a Blower Door Test in Waterford township, NJ

As part of preparing for blower door test in Waterford township, 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 ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. 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 Waterford township, NJ.
