What Is A Blower Door Test?

A blower door test checks the number of air changes per hour in your home, ensuring old air is replaced with new, clean air for a healthier environment. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. Excessive air leakage can cause drafts, reduce comfort, and contribute to issues like condensation, moisture, and mold inside the home. A blower door test in Long Beach township, NJ helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Long Beach township, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. A single main exterior door is fitted with an adjustable aluminum frame and attached fabric panel to begin the setup. 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.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Long Beach township, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities.

Preparing for a Blower Door Test in Long Beach township, NJ

To prepare a home for blower door test in Long Beach township, NJ, we shut off the HVAC system and disable all exhaust fans. 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 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. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. We’re fully equipped with chalk, spray foam, and weatherstripping to collaborate with homeowners or contractors in correcting visible air leakage issues immediately. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Long Beach township, NJ.
