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. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. Too much ventilation can create drafts, discomfort, and unwanted effects like condensation, moisture accumulation, and mold inside your home. A blower door test in Newark, 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 performing blower door test in Newark, NJ, the technician ensures all exterior doors and windows are sealed and interior doors are open for steady air movement. 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.

When the fan depressurizes the home, outdoor air seeps in through leaks, crevices, and other air pathways. A sensitive device called a nanometer measures how the fan’s pressure relates to the home’s internal air pressure. 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 Newark, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. Most areas recognize 3 air changes per hour or less as the target blower door test value to ensure energy efficiency. Meeting this level during your blower door test in Newark, NJ supports energy efficiency and verifies that your home meets local codes.

Why Do I Need A Blower Door Test?

The State of NJ, together with many cities and counties, enforces the IECC (International Energy Conservation Code), which calls for blower door test on new or renovated residential properties.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Select a proper air barrier such as Tyvek or Zip Sheathing and ensure every seam is thoroughly taped for airtight sealing.
Install correctly rated insulation with the proper R-value and confirm it’s well positioned in every part 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.
Seal every transition point between conditioned and unconditioned environments, including attics, crawl spaces, and basements.
Local permitting offices often offer official compliance checklists — review the Philadelphia sample here for reference.
Local Energy Audits uses thermal imaging tools, caulk, and spray foam to detect and seal leaks directly on-site./li>
More than 90% of our tests result in a passing score within two hours, along with immediate permit documentation.

Preparing for a Blower Door Test in Newark, NJ

We begin blower door test in Newark, NJ by switching off the HVAC system and shutting down all exhaust fans throughout the home. A brief walkthrough follows, during which we verify all exterior windows and doors — even those leading to unconditioned spaces — are closed tight to preserve the thermal envelope. After all openings are closed, we choose a central exterior door, install the blower door frame and fan, and depressurize the house to 50 Pascals to gauge airflow. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. A thermal imager allows precise detection of problem areas by mapping temperature contrasts in walls, ceilings, and surfaces facing unconditioned areas. 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 the sealing process, we can promptly retest to confirm if the desired blower door score has been reached, meeting Newark, NJ energy code requirements.
