What Is A Blower Door Test?

A blower door test evaluates air changes per hour, showing how often indoor air is replaced by fresh outdoor air — a process essential for healthy living spaces. Too frequent air exchanges lead to energy waste, as every replacement requires reheating or recooling, decreasing your system’s efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Old Bridge, 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 Old Bridge, 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 fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. 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.

In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Meeting this requirement during your blower door test in Old Bridge, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Preparing for a Blower Door Test in Old Bridge, NJ

We begin blower door test in Old Bridge, NJ by switching off the HVAC system and shutting down all exhaust fans throughout 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 everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. Using a thermal imager, we detect problem areas by observing temperature variations in walls, ceilings, and other surfaces that connect to unconditioned spaces. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Old Bridge, NJ efficiency codes.
