What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Excessive air changes can bring drafts and air leakage discomfort while promoting moisture buildup, mold, and condensation. A blower door test in Little Egg Harbor, NJ locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Little Egg Harbor, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

When indoor air is extracted, outdoor air pushes in through every leak and small gap in the building. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. From these readings, the number of air changes per hour (ACH) is determined, revealing the home’s airtightness and performance efficiency in NJ.

What Is A Passing Blower Door Test Score?

In Little Egg Harbor, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Meeting this requirement during your blower door test in Little Egg Harbor, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Select a proper air barrier such as Tyvek or Zip Sheathing and ensure every seam is thoroughly taped for airtight sealing.
Fit insulation with the correct R-value and make sure it’s installed without voids across the entire building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Ensure complete sealing of all openings between conditioned rooms and unconditioned areas like basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Little Egg Harbor, NJ

We start the process of blower door test in Little Egg Harbor, NJ by ensuring all heating, air conditioning, and exhaust systems are turned off. 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. 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. By using a thermal imager, we can spot temperature variations in walls, ceilings, and other surfaces that indicate leaks into unconditioned areas. 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 perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in Little Egg Harbor, NJ.
