What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home 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 Roseland, 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?

To execute blower door test in Roseland, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. 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 Roseland, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Achieving this goal during your blower door test in Roseland, NJ promotes energy savings and demonstrates adherence to local building rules.

Preparing for a Blower Door Test in Roseland, NJ

We begin blower door test in Roseland, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond 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 pressure is lowered, outdoor air moves in with greater force, highlighting problem areas and leaks. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in Roseland, NJ.
