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. Excessive air changes force constant reheating or recooling, driving up energy use and reducing overall home efficiency. 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 River Edge, NJ identifies potential air leakage problems early so homeowners and builders can improve comfort, energy performance, and home durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

In blower door test in River Edge, NJ, every exterior door and window is shut, while interior doors stay open to allow uniform airflow inside the building. A central exterior door is used as the setup point, where an adjustable aluminum frame and fabric panel are positioned. A calibrated fan is installed onto the frame, creating a pressure difference of 50 Pascals, comparable to a continuous 20 mph wind blowing on the home.

When the fan starts pulling air out, external air enters through the smallest cracks and leakage points. A precise tool called a nanometer is used to compare the pressure generated by the fan with that inside the home. The data is converted into air changes per hour (ACH), identifying how tightly sealed and energy-efficient the house is in NJ.

What Is A Passing Blower Door Test Score?

In River Edge, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. 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. Meeting this requirement during your blower door test in River Edge, NJ helps reduce energy costs while keeping your home compliant with local building codes.

Why Do I Need A Blower Door Test?

The State of NJ and its local governments follow the IECC standards, which require blower door test on newly built or remodeled residential dwellings.

Through blower door test in River Edge, NJ, homeowners can easily find leaks. When the fan reduces internal pressure, air movement through problem areas becomes noticeable, offering chances to save energy. A blower door test may take just a few hours, yet its long-lasting impact can greatly improve your home’s comfort and energy use across NJ’ hot summers and cool winters.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use a trusted air barrier like Tyvek or Zip Sheathing, ensuring all joints and seams are properly taped and sealed.
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.
Make sure to seal all separations between conditioned and unconditioned areas, including crawl spaces, basements, and attics.
Building departments in many areas share checklists for verifying compliance — download the Philadelphia version here as a sample.
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 River Edge, NJ

Preparation for blower door test in River Edge, NJ begins with switching off the HVAC system, as well as any bathroom 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. 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. Once depressurization occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. A thermal imager helps highlight problem zones by detecting temperature variations in walls, ceilings, and areas connected to unconditioned spaces. We carry chalk, spray foam, and weatherstripping so our team can work alongside homeowners or contractors to seal visible air leakage spots right away. 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 River Edge, NJ.
