Local Context for Duct Leakage Testing in Burlington Township, NJ
The housing stock in Burlington Township consists of a broad mix of 18th-19th century historic homes, 1950s-60s suburban development, and newer growth in the eastern townships. Major access routes include Route 38, Route 206, I-295, and the NJ Turnpike.
Burlington Township sits in IECC Climate Zone 4A (Mixed-Humid), which determines the insulation R-values and air-sealing standards required by 2021 IECC (via the NJ Uniform Construction Code, N.J.A.C. 5:23). Local electric service is provided by PSE&G (northern Burlington) or Atlantic City Electric (southern Burlington), with natural gas typically served by PSE&G or New Jersey Natural Gas.
Why Burlington Township, NJ Homeowners Need Duct Leakage Testing
The building codes enforced in Burlington Township, NJ — primarily the 2015 IECC for single-family construction and the 2018 IECC for multi-family — make a duct leakage test mandatory for new and substantially-remodeled homes. Contractors in Burlington County need a passing result to close out their permit and hand over the certificate of occupancy.
But code is only part of it. Duct leaks are one of the leading causes of high energy bills in the NJ region. They also pull contaminants like mold spores and insulation fibers into the air you breathe, making testing worthwhile even on homes that aren’t under construction.
What Our Clients Say
Saima Faiz — October 2024
I recently contacted Local Energy Audits for help with a suspected duct leak. From the start, they asked all the right questions and even requested pictures to better understand the situation. Based on the information I provided, they recommended a specific service, which, surprisingly, they didn’t even sell. They didn’t charge me anything for their time, and the advice they gave was invaluable. Their honesty, professionalism, and genuine desire to help really stood out. I highly recommend them.
Max Young — September 2024
Frustrated with my high electric bills — despite an efficiency drive in lighting and appliances — I suspected HVAC was to blame but didn’t know where to start. Research suggested an energy audit, and I’m very happy I chose Local Energy Audits. Ori was extremely professional, thorough, and on-time. After the blower door test, he walked every room with me, patiently reviewing leaks and possible fixes. Particularly given the new federal tax credits, I found the price extraordinarily reasonable. Highly recommend.
Robin Rafkin — June 2024
I had called numerous companies and had numerous individuals to our house. No one could figure out the issues. Ori explained everything and fixed the issues. He and his crew are wonderful!

What to Expect During Your Burlington Township Duct Leakage Test
Your duct leakage test in Burlington Township, NJ follows a standard IECC procedure. Step one: every supply and return register is sealed off with duct mask tape. Step two: the duct blaster is mounted on the air handler or a primary return, sealing the duct system into a closed loop. Step three: the fan depressurizes the duct system to 25 Pascals, and a calibrated manometer reads the airflow required to maintain that pressure.
The airflow reading is converted to CFM per 100 square feet of conditioned floor area — the metric the IECC uses. Tests in Burlington Township homes typically finish in 30 to 60 minutes with zero disruption to your living space.
How Duct Leakage Is Measured
Duct leakage is measured in cubic feet per minute (CFM) per 100 square feet of conditioned space. Your technician uses a manometer to read small pressure variations, which directly correlates to the volume of air escaping. In Burlington Township, that number determines whether your home meets the IECC threshold of 4 CFM/100 sq ft (with air handler) or 3 CFM/100 sq ft (without).
Cost of Excessive Duct Leakage in Burlington Township, NJ
If your Burlington Township home suffers from high utility bills, uneven room-to-room comfort, or frequent HVAC repairs, duct leakage is a likely culprit. According to ENERGY STAR, typical homes lose 20–30% of conditioned air through duct leaks. That forces the HVAC to run longer to maintain setpoint, which drives up energy costs and accelerates component wear.
Duct leaks also pull dust, moisture, mold spores, and insulation fibers into the supply air — meaning they don’t just waste energy, they actively degrade indoor air quality. For Burlington County homes with basements or crawl spaces, that’s a real concern.
Rebates and Incentives for Burlington Township Homeowners
New Jersey’s energy code is the 2021 IECC, enforced through the Uniform Construction Code. The NJ Department of Community Affairs publishes statewide requirements; municipal construction officials handle permits and inspections. Homeowners in Burlington Township may qualify for NJ Clean Energy’s Home Performance with ENERGY STAR program (rebates up to $4,000 for air sealing and insulation upgrades) — details available at https://www.njcleanenergy.com/.
At the federal level, the Inflation Reduction Act’s Energy Efficient Home Improvement Credit (Section 25C) covers 30% of the cost of a home energy audit (up to $150), plus 30% of qualifying air sealing and insulation improvements (up to $1,200/year combined). Our technicians hold BPI Building Analyst Professional credentials, which is the qualification required for most New Jersey rebate programs.
Frequently Asked Questions
What’s the duct leakage threshold in Burlington Township, NJ?
Under 2021 IECC (via the NJ Uniform Construction Code, N.J.A.C. 5:23), residential ductwork must test at 4 CFM25 per 100 sq ft of conditioned space (with air handler) or 3 CFM25 per 100 sq ft (without). New construction in Burlington Township must meet this threshold before receiving a certificate of occupancy.
How long does a duct leakage test take in Burlington Township?
Most duct leakage tests in Burlington Township homes complete in 30-60 minutes, including setup, measurement, and taping off registers. Larger homes or multi-zone systems may take longer.
Do I need both a blower door test and a duct leakage test in NJ?
In most cases, yes. 2021 IECC (via the NJ Uniform Construction Code, N.J.A.C. 5:23) requires both for new residential construction. Blower door tests measure total envelope leakage; duct leakage tests isolate ductwork losses specifically. For existing homes in Burlington Township, a duct leakage test is recommended when ductwork runs through unconditioned spaces like attics, crawl spaces, or garages.
How much does duct leakage testing cost in Burlington Township?
Pricing depends on home size and testing scope. Contact Local Energy Audits at 888-213-3975 for a quote specific to your Burlington Township property.
