What Is A Blower Door Test?

A blower door test is conducted to assess air changes per hour inside a home or structure, ensuring the right balance between air leakage and fresh airflow. Too many air changes, however, can be detrimental because every time the air is replaced, it must be reheated or recooled, leading to higher energy use and lower efficiency. Excessive air circulation may cause drafts, discomfort from leaks, and indoor problems like condensation, mold, and moisture damage. A blower door test in Milltown, 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?

To execute blower door test in Milltown, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. These readings are then converted into the total number of air changes per hour (ACH), revealing how airtight the home is and how well it performs in the NJ climate.

What Is A Passing Blower Door Test Score?

In Milltown, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Meeting this benchmark in your blower door test in Milltown, NJ reduces ongoing energy costs while ensuring local regulatory compliance.

Preparing for a Blower Door Test in Milltown, NJ

Preparation for blower door test in Milltown, NJ includes turning off the air conditioning, heating, and all exhaust fans to ensure accurate results. Next, we inspect each room to confirm all exterior doors and windows are properly closed — including any leading to garages, basements, or other spaces beyond the thermal envelope. Once preparation is complete, the blower door fan and frame are installed in a centrally located exterior door. The fan then reduces pressure to 50 Pascals, allowing accurate leakage assessment. Once the home is under depressurization, exterior air infiltrates faster through cracks, helping pinpoint leaks. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. Equipped with chalk, spray foam, and weatherstripping, we can directly assist homeowners or contractors in resolving visible air leakage problems on-site. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Milltown, NJ.
