What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. Too frequent air replacement can reduce efficiency since every exchange requires your system to use more energy for heating or cooling. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Vernon, 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?

In blower door test in Vernon, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. 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 the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the NJ climate.

Preparing for a Blower Door Test in Vernon, NJ

To properly prepare for blower door test in Vernon, NJ, the HVAC system and all bathroom and kitchen fans are turned off. 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 openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. A thermal imager helps us visualize temperature differences in walls, ceilings, and surfaces that separate conditioned and unconditioned spaces. Our technicians arrive with chalk, spray foam, and weatherstripping materials, ready to work with homeowners or contractors to fix visible air leakage problems right away. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Vernon, NJ efficiency codes.
