What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. Too many air changes can result in drafts and leaks that create discomfort and lead to moisture, mold, and condensation issues. A blower door test in Carneys Point, NJ helps uncover these issues early, enabling homeowners and builders to detect air leaks, enhance energy efficiency, and ensure a more comfortable, long-lasting home.

What Our Clients Say

How Is A Blower Door Test Conducted?

When blower door test in Carneys Point, NJ is conducted, every exterior door and window is closed, and interior doors are left open to achieve uniform air movement inside. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. A calibrated fan is placed within the frame and operated to depressurize the structure to 50 Pascals — nearly the same as a 20 mph wind hitting the building.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. These figures are calculated into air changes per hour (ACH), reflecting how well the home prevents air loss and maintains efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Carneys Point, 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. Passing this threshold during your blower door test in Carneys Point, NJ ensures both energy savings and full compliance with local regulations.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Eliminate air leaks by sealing all openings between conditioned areas and unconditioned spaces, including basements and attics.

Preparing for a Blower Door Test in Carneys Point, NJ

As part of preparing for blower door test in Carneys Point, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. We then perform a brief inspection throughout the home to make sure all exterior doors and windows are tightly shut — even those opening to garages, basements, or spaces outside the thermal envelope. With the home properly sealed, we mount the blower door frame and fan in a central exterior door, using it to depressurize to 50 Pascals for exact airflow readings. After depressurization, air infiltration from outdoors increases, allowing faster and more accurate leak detection. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. We can retest right after sealing to check whether the desired blower door score has been met, ensuring full compliance with Carneys Point, NJ energy standards.

For contractors conducting blower door test in Carneys Point, NJ, well-insulated homes generally require only minimal on-site corrections during the test.
