What Is A Blower Door Test?

A blower door test helps determine the air changes per hour to confirm that your home has sufficient fresh air replacement. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing 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 North Brunswick, NJ helps discover hidden leaks early so homeowners can save energy, enhance comfort, and improve home resilience.

What Our Clients Say

How Is A Blower Door Test Conducted?

Before blower door test in North Brunswick, NJ, every exterior door and window is closed securely, while interior doors stay open to let air move evenly around the home. One primary exterior doorway is used, where a flexible aluminum frame and fabric panel are mounted tightly. Technicians mount a calibrated fan onto the frame to achieve 50 Pascals of depressurization — similar to a constant 20 mph wind acting on the home.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

Homes throughout North Brunswick, NJ are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Achieving compliance in your blower door test in North Brunswick, NJ helps improve energy efficiency and meet all local code mandates.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Install an effective air barrier, for example Tyvek or Zip Sheathing, and make certain all seams are sealed with durable tape.
Use insulation of the correct R-value and confirm that it’s tightly installed throughout every section of the building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close gaps and penetrations between conditioned zones and unconditioned sections like attics, basements, and crawl spaces.
Local code offices often issue compliance checklists — access the Philadelphia example here for reference.
With caulk, spray foam, and advanced thermal imaging, Local Energy Audits locates and seals leaks efficiently on-site./li>

Preparing for a Blower Door Test in North Brunswick, NJ

Before starting blower door test in North Brunswick, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. 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. After sealing everything, we install the blower door frame and fan in a central exterior door and use it to depressurize the home to 50 Pascals for accurate airflow data. After the pressure drops, outdoor air enters through gaps more noticeably, making leaks easier to identify. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. After sealing, we perform a follow-up test to determine if the desired blower door score meets the efficiency standards required in North Brunswick, NJ.
