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. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Woodbridge, NJ identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Woodbridge, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. After setup, a calibrated fan is attached to the frame to lower the air pressure inside the house to 50 Pascals, equivalent to a 20 mph wind.

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?

Houses in Woodbridge, NJ are required to meet the standards of the 2015 International Energy Conservation Code (IECC) or the latest locally adopted version. An efficient home in most regions will achieve 3 air changes per hour or less during a blower door test. Meeting this level during your blower door test in Woodbridge, NJ supports energy efficiency and verifies that your home meets local codes.

Preparing for a Blower Door Test in Woodbridge, NJ

Before starting blower door test in Woodbridge, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. We follow with a quick walkthrough to ensure all exterior doors and windows are fully closed — including those that connect to garages, basements, or any part outside the thermal envelope. After sealing the home, the blower door fan is installed in a central exterior doorway and used to lower pressure to 50 Pascals to measure airflow and leakage effectively. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Woodbridge, NJ energy standards.
