What Is A Blower Door Test?

A blower door test is designed to measure air changes per hour inside homes, promoting a balance between airtightness and necessary ventilation. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in East Orange, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in East Orange, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

Residential buildings in East Orange, NJ must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Passing this requirement during a blower door test in East Orange, NJ keeps your home efficient and aligned with local building code standards.

Preparing for a Blower Door Test in East Orange, NJ

To ensure accuracy during blower door test in East Orange, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. 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 sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in East Orange, NJ.
