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. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Too much air movement from leaks can cause uncomfortable drafts, moisture accumulation, and mold or condensation issues indoors. A blower door test in Long Hill, 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?

To conduct blower door test in Long Hill, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

What Is A Passing Blower Door Test Score?

In Long Hill, NJ, residential properties must meet the energy efficiency criteria outlined in the 2015 International Energy Conservation Code (IECC) or updated local versions. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Complying with this benchmark during a blower door test in Long Hill, NJ helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in Long Hill, NJ

When preparing for blower door test in Long Hill, NJ, we first switch off the home’s heating, cooling, and exhaust systems. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. We come prepared with chalk, spray foam, and weatherstripping, allowing us to assist homeowners or contractors in sealing visible air leakage points on the spot. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Long Hill, NJ energy standards.
