A blower door test is performed to identify the rate of air changes per hour, confirming your home receives a healthy exchange of fresh air. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage.

What Our Clients Say

How Is A Blower Door Test Conducted?

To complete blower door test in Mendham township, NJ, all exterior openings are sealed, and interior doors are kept open to ensure equal airflow throughout the property. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. 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?

Residential buildings in Mendham township, NJ must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. 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 Mendham township, NJ

To prepare for blower door test in Mendham township, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. With all openings sealed, we place the blower door frame and fan in a main exterior door and use it to depressurize the structure to 50 Pascals for precise testing results. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. Using chalk, spray foam, and weatherstripping, we assist homeowners and contractors in addressing visible air leakage areas on-site. 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 Mendham township, NJ.
