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. Frequent air replacement can harm energy performance, as each exchange requires reheating or recooling the air. 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 Wall, NJ detects early-stage air leaks, enabling effective energy use and a more durable, comfortable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Wall, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

As the fan exhausts indoor air, outside air starts seeping into the home through small leaks and gaps. Using a nanometer device, we assess how the pressure from the fan differs from the home’s natural air pressure. The test results are converted into air changes per hour (ACH), which determines the airtightness and performance level of the home in NJ weather.

What Is A Passing Blower Door Test Score?

In Wall, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. For most regions, achieving 3 air changes per hour or less on a blower door test ensures that the home is properly energy efficient. Achieving compliance in your blower door test in Wall, NJ helps improve energy efficiency and meet all local code mandates.

Why Do I Need A Blower Door Test?

Both NJ and local jurisdictions adopt the IECC energy code, making blower door test mandatory for new and renovated residential structures.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.

Preparing for a Blower Door Test in Wall, NJ

To prepare a home for blower door test in Wall, NJ, we shut off the HVAC system and disable all exhaust fans. Next, our team walks through the home to verify that every exterior door and window is sealed shut — including access points to unfinished basements, garages, or areas beyond the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. Using a thermal imager, we locate inefficiencies by observing temperature differences in walls, ceilings, and surfaces separating conditioned and unconditioned areas. 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 Wall, NJ.
