What Is A Blower Door Test?

A blower door test measures how many air changes per hour occur in your home, ensuring fresh air circulation and improved indoor air quality. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Glen Rock, 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 blower door test in Glen Rock, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. Technicians select one central exterior door and install an adjustable aluminum frame along with a fabric panel for testing. A precisely calibrated fan is installed on the frame to reduce the air pressure inside to 50 Pascals, equal to a steady 20 mph wind outdoors.

As air is drawn out by the fan, it causes outdoor air to infiltrate through existing leaks and gaps in the structure. Using an advanced nanometer, we evaluate the pressure difference between the fan system and the home’s interior environment. The gathered results are converted into air changes per hour (ACH) to determine how well-sealed and efficient the home is in the NJ climate.

What Is A Passing Blower Door Test Score?

In Glen Rock, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. In most regions, homes must achieve 3 air changes per hour or less on a blower door test to meet energy efficiency standards. Meeting this benchmark in your blower door test in Glen Rock, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

Preparing for a Blower Door Test in Glen Rock, NJ

To ensure accuracy during blower door test in Glen Rock, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. 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 completing sealing improvements, we retest immediately to ensure the desired blower door score is met and the home complies with efficiency standards in Glen Rock, NJ.
