What Is A Blower Door Test?

A blower door test measures the air changes per hour within a home or building. Air exchange is a normal and healthy process that allows stale indoor air to be replaced with fresh air. When a home experiences excessive air changes, the HVAC system must reheat or recool more frequently, increasing energy use and reducing efficiency. Too many air changes can create drafts and discomfort due to leaks and may also lead to condensation, moisture buildup, and mold growth indoors. A blower door test in Cliffside Park, 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?

In blower door test in Cliffside Park, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. Using a highly accurate nanometer, we compare the fan-induced pressure to the natural air pressure inside the home. Measurements are expressed as air changes per hour (ACH), showing how effectively the home retains conditioned air in the NJ environment.

What Is A Passing Blower Door Test Score?

In Cliffside Park, NJ, compliance with the 2015 International Energy Conservation Code (IECC) or subsequent locally adopted versions is typically mandatory for residential properties. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance. Achieving compliance in your blower door test in Cliffside Park, NJ helps improve energy efficiency and meet all local code mandates.

Apply an appropriate air barrier, such as Tyvek or Zip Sheathing, making sure every seam is correctly taped for maximum performance.
Use insulation that has the designated R-value and confirm it’s properly applied throughout the building envelope for maximum efficiency.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close and seal every opening between heated or cooled spaces and unconditioned areas such as basements, attics, and crawl spaces.
Local building authorities commonly offer checklists to verify code compliance — review the Philadelphia example here.
Our team at Local Energy Audits employs thermal imaging, caulk, and spray foam to locate and repair leaks efficiently on-site./li>

Preparing for a Blower Door Test in Cliffside Park, NJ

Before starting blower door test in Cliffside Park, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. We continue with a walkthrough inspection to confirm every exterior door and window is firmly closed — especially those to unconditioned 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. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. A thermal imager allows us to pinpoint problem spots by highlighting temperature contrasts in walls, ceilings, and surfaces exposed to unconditioned spaces. We bring the tools and materials—chalk, spray foam, and weatherstripping—to work with homeowners or contractors in fixing visible air leakage issues immediately. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Cliffside Park, NJ.
