What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. 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 North Arlington, NJ detects air leaks early on, helping builders and homeowners boost efficiency and strengthen overall home comfort.

What Our Clients Say

How Is A Blower Door Test Conducted?

To execute blower door test in North Arlington, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One chosen exterior door is equipped with an adjustable aluminum frame and fabric panel for test installation. A calibrated fan is then attached to the frame and used to depressurize the home to 50 Pascals, which is about the same as a steady 20 mph wind pushing against the structure.

When the fan pulls air out, outdoor air enters the house through cracks, openings, and unsealed areas. Using a sensitive instrument known as a nanometer, we measure the fan’s pressure against the home’s internal pressure. The collected data converts to air changes per hour (ACH), demonstrating how tightly sealed and efficient the home remains in NJ climates.

What Is A Passing Blower Door Test Score?

In North Arlington, NJ, new construction typically follows the 2015 International Energy Conservation Code (IECC) or an updated edition implemented by local codes. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. By meeting this standard in your blower door test in North Arlington, NJ, you can enjoy lower utility bills and peace of mind with code compliance.

Why Do I Need A Blower Door Test?

The State of NJ and local municipalities have implemented the IECC code, which mandates blower door test on new and remodeled residential homes. Our experts assist home builders, contractors, and homeowners needing blower door test in North Arlington, NJ to ensure compliance with energy codes and complete final permits. A duct leakage test requirement applies if ducts or HVAC units are positioned outside the structure’s thermal envelope. Learn more about energy code compliance.

Homeowners benefit from blower door test in North Arlington, NJ because depressurization exposes airflow through cracks, helping identify leaks and boost efficiency. 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.

Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.

Preparing for a Blower Door Test in North Arlington, NJ

As part of preparing for blower door test in North Arlington, NJ, we power down the HVAC system along with kitchen and bathroom exhaust fans. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. After depressurization, air from outside rushes in through cracks and gaps, making leak detection much easier. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to 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. Once sealing is finished, we conduct an instant retest to ensure the desired blower door score is reached, confirming compliance with North Arlington, NJ building codes.
