What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Commercial, NJ helps pinpoint problem areas early, improving insulation performance, comfort, and home lifespan.

What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Commercial, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

In Commercial, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. By meeting this standard in your blower door test in Commercial, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

Preparing for a Blower Door Test in Commercial, NJ

We begin blower door test in Commercial, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Commercial, NJ energy standards.
