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 can cause problems since each exchange requires reheating or recooling, resulting in greater energy consumption and reduced efficiency. 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 Sparta, NJ detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Sparta, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. 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.

When air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal 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 Sparta, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. A result of 3 air changes per hour or less is generally required in most areas to confirm the home’s energy efficiency. By meeting this standard in your blower door test in Sparta, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

Preparing for a Blower Door Test in Sparta, NJ

We begin blower door test in Sparta, 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 depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Sparta, NJ.
