Duct Leakage Testing in Justin, TX
Are you in need of a Duct Leakage Test in Justin, TX? Our certified team performs duct leakage testing efficiently, ensuring homeowners, builders, and contractors comply with Texas energy codes.
In compliance with the 2018 International Energy Conservation Code (IECC), duct leakage testing must be performed in new residential dwellings whenever any portion of the HVAC system, including ductwork or the air handler, is situated outside the conditioned space. If your home or building requires compliance testing, our experienced team offers high-quality and cost-efficient testing services in Justin, TX, and surrounding locations.
What Is a Duct Leakage Test?
A duct leakage test determines how much air is escaping from the HVAC duct system. Leaky ducts can lead to:
- Wasted energy leading to inflated utility expenses.
- Inconsistent heating and cooling, causing discomfort throughout your space.
- Reduced energy efficiency, making heating and cooling systems strain.
- Unwanted particles entering ducts, making the indoor environment less healthy.
In duct leakage testing, a duct blower system forces air into the ductwork to determine the rate of air leakage. If too much air is leaking, properly sealing the ducts can lower energy waste and help your home pass necessary code requirements.


Do You Need a Duct Leakage Test in Justin, 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).

- Your home has uneven heating and cooling issues.
- You want to ensure your HVAC system is operating efficiently.
When your home or project requires duct leakage testing in Justin, TX, we offer fast appointments and same-day results to keep everything moving smoothly.

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.
