Duct Leakage Testing in Duncanville, TX
Want to schedule a Duct Leakage Test in Duncanville, TX? Our skilled professionals perform duct leakage tests quickly and precisely, helping homeowners, contractors, and builders adhere to Texas energy codes.
The 2018 International Energy Conservation Code (IECC) states that new residential dwellings must meet duct leakage testing requirements if any section of the HVAC system, including ductwork or the air handler, is located outside the conditioned space. If your home or building must undergo compliance testing, we are here with professional and affordable testing services in Duncanville, TX, and nearby locations.
What Is a Duct Leakage Test?
A duct leakage test evaluates the level of air leakage in the HVAC duct system. When ducts aren’t sealed properly, they may cause:
- Escalating energy expenses due to air leakage from ducts.
- Fluctuating indoor temperatures, leading to an unpleasant living or working space.
- HVAC systems working overtime due to decreased efficiency.
- Increased indoor pollutants as dust and debris enter through leaky ducts.
The duct leakage test is performed by pressurizing the ductwork with a duct blower system to measure the extent of air loss. If excessive duct leakage is present, sealing the system can reduce energy waste and ensure your home meets all code requirements.


Do You Need a Duct Leakage Test in Duncanville, TX?

Texas Energy Code Requirements for Duct Leakage
Under the 2018 IECC, homes in Texas must meet specific duct leakage limits:
- If the air handler or ducts are outside the thermal envelope, total duct leakage must be 4 CFM per 100 sq. ft. or lower.
- If the entire duct system is inside the conditioned space, a duct leakage test is not required.
Failing to meet these requirements can delay your project. Our expert technicians ensure quick and accurate testing to help you pass your inspection.
