Improve insulation performance and meet energy code requirements through thorough blower door test in Atlantic City, NJ. Our licensed professionals help homeowners, builders, and contractors identify air leaks, enhance comfort, and achieve NJ energy compliance.

What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. Too many air exchanges make heating and cooling systems work harder, increasing energy consumption and lowering 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 Atlantic City, NJ allows early detection of air leaks, helping homeowners and builders boost efficiency and maintain a comfortable, durable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

To perform blower door test in Atlantic City, NJ, all exterior doors and windows are tightly sealed, while interior doors remain open to promote balanced airflow throughout the home. A single central exterior door is designated, where the blower door’s aluminum frame and fabric panel are set up. A calibrated fan mounted on the frame reduces the home’s pressure to 50 Pascals, simulating the force of a continuous 20 mph wind.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These measurements are used to calculate air changes per hour (ACH), which reflects the home’s airtightness and performance under NJ weather.

What Is A Passing Blower Door Test Score?

In Atlantic City, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. Typically, a passing blower door test result is 3 air changes per hour or lower, which indicates good energy efficiency. Complying with this benchmark during a blower door test in Atlantic City, NJ helps cut energy expenses and meet local building regulations.

Preparing for a Blower Door Test in Atlantic City, NJ

To properly prepare for blower door test in Atlantic City, NJ, the HVAC system and all bathroom and kitchen fans are turned off. We proceed with a quick home walkthrough, checking that every exterior door and window is tightly shut — including ones that lead to unfinished or unconditioned spaces outside the thermal envelope. After ensuring the home is airtight, we install the blower door frame and fan in a central exterior door and depressurize the house to 50 Pascals to record airflow and leakage data accurately. Once the structure is depressurized, outside air penetrates more actively, exposing any leaks and weak points. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Atlantic City, NJ efficiency codes.
