Duct Leakage Testing

Get duct leakage testing in Texas for final inspections, closeout, and energy code documentation.

Duct leakage testing measures how much air escapes from a building’s duct system. This test confirms whether the system meets IECC and local code requirements and helps identify installation issues that may affect efficiency or comfort.

TEST METHOD

What Is Duct Leakage Testing?

Duct leakage testing measures air loss through seams, joints, and construction connections.

  • Pressurized duct testing at 25 Pascals (CFM25)

  • Pass/fail results based on IECC thresholds

  • Verification that air reaches conditioned spaces

  • Identification of visible leakage points (when accessible)

  • Code-ready documentation for inspectors and permitting

DUCT LEAKAGE TESTING

When Duct Leakage Testing Is Needed

At specific points in the construction and permitting process, especially for ducted HVAC systems located outside conditioned space, duct leakage testing is required for compliance.

  • Energy Code Requirements

    IECC requires duct leakage testing for many commercial and tenant-finish projects, particularly when ductwork is outside the thermal envelope.

  • Pre-Cover Verification

    Testing before drywall or ceiling installation allows installers to correct leaks before systems are concealed.

  • Final Inspection and Certificate of Occupancy

    Many jurisdictions require a passing duct leakage test as part of the mechanical final approval process.

  • Installation Quality Checks

    Commonly used for tenant finish-outs, retail spaces, offices, renovations, and small commercial projects.

WHY IT MATTERS

Why Duct Leakage Testing Matters

Feature Items:

  • Comfort & Air Delivery

    Excess leakage reduces the amount of conditioned air reaching occupied spaces.

  • Energy Efficiency

    Leaky ducts increase energy use and equipment runtime.

  • Operating Costs

    Poor duct performance drives higher utility and maintenance costs.

  • Inspection & Approval Outcomes

    Passing duct leakage results are often required to obtain permit closure and inspection clearance.
