What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. 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 Pemberton borough, 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 Pemberton borough, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. 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 air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

In Pemberton borough, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. In most cases, passing the blower door test means reaching 3 air changes per hour or less, proving efficient home sealing. Achieving this standard in your blower door test in Pemberton borough, NJ lowers utility bills and guarantees adherence to local code requirements.

Preparing for a Blower Door Test in Pemberton borough, NJ

To properly prepare for blower door test in Pemberton borough, NJ, the HVAC system and all bathroom and kitchen fans are turned off. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. After the home is depressurized, incoming outdoor air becomes more intense, making leak points easy to locate. Using a thermal imager, we easily locate air leaks by noting temperature differences on walls, ceilings, and other surfaces adjacent to unconditioned spaces. We’re equipped with chalk, spray foam, and weatherstripping materials, so we can partner with homeowners or contractors to repair visible air leakage problems right on-site. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Pemberton borough, NJ efficiency codes.
