Our certified technicians identify and measure air leaks in ductwork to help homeowners and builders in Bucks County improve comfort, reduce energy waste, and achieve compliance with state requirements.
Local Context for Duct Leakage Testing in Southampton, PA
The housing stock in Southampton consists of ranging from 1700s historic homes to massive 1950s postwar developments (like Levittown) to newer construction. Major access routes include I-95, Route 1, Route 611, and the PA Turnpike.
Southampton sits in IECC Climate Zone 4A (Mixed-Humid), which determines the insulation R-values and air-sealing standards required by 2018 IECC (statewide under the PA Uniform Construction Code, Act 45). Local electric service is provided by PECO, with natural gas typically served by PECO.
Why Bucks County Homes Benefit from Duct Leakage Tests
Most jurisdictions in PA now enforce the 2015 IECC (International Energy Conservation Code) for single-family homes and the 2018 IECC for multi-family buildings. For builders and HVAC contractors working in Southampton and the rest of Bucks County, this means a duct leakage test plus a blower door test are required for any newly built or substantially remodeled home.
Ductwork is one of the biggest sources of air leakage in homes throughout Pennsylvania, New Jersey, and Delaware. Leaked air drives up utility bills, overworks HVAC equipment, and pulls dust and insulation particles into living spaces. Duct leakage testing is the diagnostic step that exposes the problem so it can actually be fixed.
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!
John Lentz — December 2023
Chris was a fast and efficient tech. Whole test took less than a half hour from arrival to departure and provided exactly what was needed.

How We Perform a Duct Leakage Test in Southampton
Here’s the step-by-step of a duct leakage test in Southampton, PA: your technician tapes off every supply and return register in the house, leaving only the main return or air handler exposed. A calibrated duct blaster fan is mounted at that opening, and the system is pulled down to a controlled negative pressure (typically 25 Pascals).
At that pressure, the manometer reads exactly how much air is escaping through leaks. The total gets reported in CFM — cubic feet per minute — and compared to the IECC threshold for your home’s size. Most Southampton tests run 30 to 60 minutes, no mess, no disruption.
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 Southampton, 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).
Why Duct Leaks Drive Up Your Bills
A leaky duct system forces your HVAC to work harder for the same temperature result. According to ENERGY STAR, the average home loses 20–30% of its conditioned air through ductwork, which means your furnace or AC is running 20–30% longer than it should to keep your Southampton home comfortable.
Over time, that extra runtime shortens equipment life, increases repair frequency, and adds up to real money on monthly bills. Duct leaks also pull unfiltered air from attics, crawl spaces, and wall cavities — meaning dust, mold, and moisture end up circulating through your Bucks County home’s living spaces.
Rebates and Incentives for Southampton Homeowners
Pennsylvania enforces the 2018 IECC statewide under the Uniform Construction Code (Act 45). Local municipalities handle permits through their construction code officials; Philadelphia has additional city-specific air barrier requirements. Homeowners in Southampton may qualify for PECO’s Smart Home Rebates (for PECO service territory) and Act 129 utility efficiency programs — details available at https://www.peco.com/WaysToSave/ForYourHome.
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 and RESNET HERS Rater certifications, which is the qualification required for most Pennsylvania rebate programs.
Frequently Asked Questions
What’s the duct leakage threshold in Southampton, PA?
Under 2018 IECC (statewide under the PA Uniform Construction Code, Act 45), 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 Southampton must meet this threshold before receiving a certificate of occupancy.
How long does a duct leakage test take in Southampton?
Most duct leakage tests in Southampton 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 PA?
In most cases, yes. 2018 IECC (statewide under the PA Uniform Construction Code, Act 45) requires both for new residential construction. Blower door tests measure total envelope leakage; duct leakage tests isolate ductwork losses specifically. For existing homes in Southampton, a duct leakage test is recommended when ductwork runs through unconditioned spaces like attics, crawl spaces, or garages.
