What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Vineland, NJ enables early identification of air leaks, helping improve comfort, durability, and energy savings.

What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Vineland, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Residential buildings in Vineland, NJ must adhere to the 2015 International Energy Conservation Code (IECC) or newer versions adopted by city or county regulations. To meet efficiency standards in most areas, homes should record 3 air changes per hour or less on a blower door test. Reaching this target in your blower door test in Vineland, NJ helps maintain lower energy bills and fulfills local code obligations.

Why Do I Need A Blower Door Test?

Preparing for a Blower Door Test in Vineland, NJ

We begin blower door test in Vineland, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. 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. 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. Once pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. 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 the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Vineland, NJ energy code requirements.
