What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in East Hanover, NJ helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

When conducting blower door test in East Hanover, NJ, technicians close all exterior doors and windows and keep interior doors open for consistent air movement. An adjustable aluminum frame and fabric panel are placed within a central exterior doorway to conduct the test. 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 drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

What Is A Passing Blower Door Test Score?

In East Hanover, NJ, all new homes must comply with the 2015 International Energy Conservation Code (IECC) or more current codes enforced by local jurisdictions. In most jurisdictions, 3 air changes per hour or less is the benchmark for acceptable blower door test results and energy efficiency. Meeting this requirement during your blower door test in East Hanover, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Preparing for a Blower Door Test in East Hanover, NJ

Getting ready for blower door test in East Hanover, NJ involves turning off all heating, cooling, and exhaust ventilation systems. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside 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. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. Once sealing work is done, we immediately retest to verify that the desired blower door score has been achieved for compliance with local standards in East Hanover, NJ.
