What Is A Blower Door Test?

A blower door test is performed to record air changes per hour in buildings, confirming that fresh air regularly replaces stale indoor air. If air changes happen too often, it forces your system to reheat or recool the air repeatedly, wasting energy and lowering performance. When air changes occur too often, they can result in drafts, air leakage discomfort, and moisture-related problems such as condensation and mold. A blower door test in Woodbury, NJ makes it easier to locate leaks and inefficiencies early, ensuring lasting comfort and reduced energy waste.

What Our Clients Say

How Is A Blower Door Test Conducted?

To conduct blower door test in Woodbury, NJ, exterior doors and windows are closed properly, while interior doors remain open to help maintain even air movement. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. Next, a calibrated fan is mounted on the frame to reduce indoor pressure to 50 Pascals — similar to the force of a 20 mph wind on the building.

As the fan removes air from inside, exterior air flows in through leaks and gaps in the building envelope. With the help of a nanometer, we determine the pressure difference between the fan’s airflow and the home’s internal conditions. 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 Woodbury, NJ, homes generally must comply with the requirements of the 2015 International Energy Conservation Code (IECC) or newer editions enforced by local authorities. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Reaching this target in your blower door test in Woodbury, NJ helps maintain lower energy bills and fulfills local code obligations.

Why Do I Need A Blower Door Test?

NJ, along with many city governments, enforces the IECC, which requires blower door test for residential projects after construction or renovation. Our team frequently assists home builders, contractors, and homeowners performing blower door test in Woodbury, NJ to verify compliance and secure permit approval. A duct leakage test may also be performed when ductwork or HVAC equipment extends beyond the thermal envelope. Learn more about energy code compliance.

There are many benefits of blower door test in Woodbury, NJ for homeowners. When the fan lowers indoor pressure, leaks become visible, allowing for easy identification of inefficiencies and energy-saving opportunities. A blower door test usually takes just a few hours but delivers a long-lasting impact on your home’s comfort, performance, and efficiency—particularly during NJ’ hot summers and cool winters.

How To Pass A Blower Door Test:

Anticipate potential air leaks before testing begins.
Use a reliable air barrier like Tyvek or Zip Sheathing and make sure all seams are securely taped.
Install insulation with the appropriate R-value and ensure it is correctly fitted across the entire 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 cracks and openings between conditioned interiors and unconditioned areas such as crawl spaces, attics, and basements.
Local construction departments often include compliance guides — you can download the Philadelphia checklist here.
Local Energy Audits uses professional-grade thermal imaging, caulk, and spray foam to locate and close leaks during the visit./li>
Over 90% of projects pass within two hours, and we immediately provide the required paperwork to close out the building permit.

Preparing for a Blower Door Test in Woodbury, NJ

To get ready for blower door test in Woodbury, NJ, our team turns off the HVAC system and shuts down kitchen and bathroom fans. Next, a brief home walkthrough ensures every exterior door and window is closed — even those opening to unconditioned areas like garages or basements 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 occurs, outdoor air enters the home more aggressively, revealing leaks more clearly. By employing a thermal imager, we detect heat loss by identifying temperature variations in walls, ceilings, and other surfaces leading to unconditioned zones. We carry chalk, spray foam, and weatherstripping materials, allowing us to work directly with homeowners or contractors to fix visible air leakage issues on-site. After all leaks are sealed, we retest immediately to confirm the desired blower door score has been met and that your home satisfies efficiency requirements in Woodbury, NJ.
