Certified Duct Leakage
Testing
Trusted testing. Same-day results. Helping Austin builders & homeowners pass inspections and improve comfort.
What Is Duct Leakage Testing — and Why Does It Matter?
Leaky ducts don’t just waste energy — they can push projects out of code, create uncomfortable living conditions, and even lead to mold. For homeowners, that means higher bills and less comfort. For builders, it can mean failed inspections and costly delays.
Our duct leakage testing in Austin, TX (often called a duct blaster test) measures the airtightness of your HVAC system against strict IECC energy code standards. In most cases, allowable leakage is no more than 4.0 CFM per 100 sq. ft. of floor area (about 4% of total airflow).
With same-day results, our certified technicians give builders the compliance they need and homeowners the comfort and efficiency they want. If leakage is above the limit, we’ll pinpoint the problems and guide you to solutions.
How Our Duct Leakage Testing
Process Works
At Austin Energy Testing, we follow a proven process to deliver same-day duct leakage test results that keep projects on code and homes comfortable.
Step 1: Preparation
We coordinate with you or your HVAC contractor at the right stage — rough-in or final inspection for builders, and Energy Final for homeowners. For existing homes, we can test anytime as long as we have access to all rooms with vents.
Step 2: Equipment Setup
All supply and return registers are sealed. We then connect a certified duct blaster fan to a central return (or air handler) to depressurize the system. A pressure probe monitors test pressure throughout.
Step 3: Testing
The ducts are pressurized to 25 Pascals, and airflow is measured. Our technician records the leakage rate in CFM (cubic feet per minute) and compares it against IECC code limits for your home’s size.
Step 4: Leak Detection & Reporting
If leakage is above code, we help identify problem areas and provide clear guidance. Whether you’re a builder or homeowner, you’ll receive same-day results to avoid costly re-tests and improve efficiency.
