What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Woodbine, NJ helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

When performing blower door test in Woodbine, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. A main exterior door is selected for setup, with an adjustable aluminum frame and fitted fabric panel placed in position. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

Homes built in Woodbine, NJ are expected to comply with the 2015 International Energy Conservation Code (IECC) or any newer local versions in effect. In most locations, 3 air changes per hour or less is the standard blower door test result for efficient home performance. Achieving this goal during your blower door test in Woodbine, NJ promotes energy savings and demonstrates adherence to local building rules.

Preparing for a Blower Door Test in Woodbine, NJ

When preparing for blower door test in Woodbine, NJ, we first switch off the home’s heating, cooling, and exhaust systems. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements outside the thermal envelope. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. Through the use of a thermal imager, we find problem zones by detecting uneven temperatures in walls, ceilings, and surfaces connected to unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Woodbine, NJ.
