Duct Leakage Testing in Lewisville, TX
Searching for a reliable Duct Leakage Test in Lewisville, TX? Our certified experts offer quick and precise duct leakage testing, ensuring homeowners, builders, and contractors comply with Texas energy code requirements.
According to the 2018 International Energy Conservation Code (IECC), it is compulsory for newly built residential dwellings to undergo duct leakage testing when any part of the HVAC system, including ductwork or the air handler, is placed outside the conditioned space. If your home or building must undergo compliance testing, we are here with professional and affordable testing services in Lewisville, TX, and nearby locations.
What Is a Duct Leakage Test?
A duct leakage test evaluates the volume of air that leaks from the HVAC duct system. Duct leaks may cause:
- Higher electricity and gas bills caused by duct inefficiencies.
- Poor temperature regulation, leaving certain rooms too warm or too chilly.
- Poor HVAC efficiency, forcing the system to run longer and harder.
- Declining air quality caused by unfiltered contaminants seeping into the ducts.
During duct leakage testing, a duct blower system pressurizes the ductwork to evaluate the level of air leakage. If a duct leakage test reveals excessive air loss, sealing the ducts can improve energy efficiency and help your home meet code standards.


Do You Need a Duct Leakage Test in Lewisville, TX?
You may need a duct leakage test if:
- You are building a new home that requires energy code compliance.
- Your HVAC system’s ductwork or air handler is located outside the conditioned space (e.g., in an attic, crawl space, or garage).
- You are experiencing high energy costs and suspect leaky ducts
- Your home has uneven heating and cooling issues.
- You want to ensure your HVAC system is operating efficiently.
For fast and efficient duct leakage testing in Lewisville, TX, we offer convenient scheduling and same-day results to help you meet your deadlines.

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.

Our Duct Leakage Test Process
Our certified duct leakage testing process includes:
Step 1: System Preparation
- All registers and vents are sealed.
- The duct blaster fan is connected to the air handler or a return vent.
Step 2: Pressurizing the System
- The fan pressurizes the duct system to detect leaks.
- A digital pressure gauge measures total air loss.
Step 3: Analyzing the Results
- We compare the leakage rate to Texas energy code limits.
- If the system passes, we provide a certified report for compliance.
- If the system fails, we offer recommendations for sealing improvements.
We ensure your project stays on schedule by providing same-day results and guidance on how to meet duct leakage requirements.
