Blower Door Test in North Bergen, NJ

Enhance comfort and confirm compliance with detailed blower door test in North Bergen, NJ. Our certified specialists support homeowners, builders, and contractors by locating hidden air leaks, improving efficiency, and achieving NJ energy code compliance.

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. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. Too frequent air changes can produce drafts and discomfort from leaks, while also increasing the risk of condensation, moisture, and mold. A blower door test in North Bergen, NJ assists in finding and sealing air leaks early to improve home comfort, energy efficiency, and overall durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in North Bergen, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One central exterior door is chosen, where an adjustable aluminum frame and durable fabric panel are securely installed. 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 air is drawn out by the fan, outdoor air seeps in through unsealed joints and hidden cracks. Using a nanometer, we accurately compare the pressure difference between the fan output and the home’s interior. 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 North Bergen, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. In most areas, an acceptable blower door test result is 3 air changes per hour or less, confirming that the home achieves optimal energy efficiency. Achieving this standard in your blower door test in North Bergen, NJ lowers utility bills and guarantees adherence to local code requirements.

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.

It only takes a few hours to perform a blower door test, but the long-lasting impact on comfort and efficiency is felt through NJ’ hot summers and cool winters.

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.
  • Use insulation featuring the proper R-value and verify complete, gap-free coverage across 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 all openings between conditioned and unconditioned areas, including basements, attics, and crawl spaces.
  • Many building departments provide step-by-step compliance guides — you can find the Philadelphia example here.
  • Our professionals at Local Energy Audits use caulk, spray foam, and thermal imaging to detect and seal leaks on-site for better efficiency./li>

Preparing for a Blower Door Test in North Bergen, NJ

To prepare for blower door test in North Bergen, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. After that, we check the entire home to confirm all exterior doors and windows are tightly secured — even those leading to garages, unfinished basements, or other spaces outside the thermal envelope. After ensuring the home is fully sealed, we mount the blower door fan and frame on a central exterior door and depressurize the interior to 50 Pascals for accurate testing. 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. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. Once sealing is complete, we perform an immediate retest to verify that the desired blower door score is achieved and that your home meets all energy efficiency requirements in North Bergen, NJ.
