What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. 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 Mount Laurel, NJ helps spot air leaks before they worsen, improving efficiency, comfort, and long-term structural quality.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in Mount Laurel, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. With a nanometer, we record and compare the pressure produced by the fan to the pressure inside the house. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in NJ.

Preparing for a Blower Door Test in Mount Laurel, NJ

When preparing for blower door test in Mount Laurel, NJ, we first switch off the home’s heating, cooling, and exhaust systems. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. With the home sealed, we select a main exterior door, install the blower door setup, and use the fan to depressurize to 50 Pascals, enabling accurate airflow measurement. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. 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 leaks are addressed, we perform another test to confirm the desired blower door score and verify compliance with local efficiency regulations in Mount Laurel, NJ.
