Signs Your Ductwork Needs Repair
We routinely find that Central Texas homes lose 10% to 30% of conditioned air through duct leaks hidden in attics, crawlspaces, and wall cavities. That loss adds up on your utility bill and strains your HVAC system.
Watch for these warning signs:
- Uneven temperatures: Rooms that stay noticeably hotter or cooler than the rest of the house
- Rising energy costs: Unexplained increases in your monthly utility bills
- Weak airflow: Registers that barely push air even when the system is running hard
- Noises from vents: Popping, whistling, or rattling sounds during a heating or cooling cycle
- Dust and odors: Excessive dust buildup or musty smells coming from supply registers
Why Austin Ductwork Takes a Beating
Austin attic temperatures routinely exceed 130°F in summer. That sustained heat degrades flexible duct material, dries out mastic sealant at plenum connections, and breaks down duct insulation over time. Sheet metal ductwork expands and contracts with temperature swings, loosening joints that held sound for years.
We work across all of Austin’s building stock, from older central-city homes with aging duct systems to newer suburban construction where flex duct runs can shift, sag, or separate during settling. Pest activity, remodeling work, and deferred maintenance round out the causes we see most often on the job.

How Our Duct Repair Process Works
Every job starts with a thorough inspection and duct pressure test to measure air leakage and map where it’s coming from. From there, the repair scope is straightforward:
- Sealing leaks and gaps: We apply mastic sealant or appropriate tape at joints, seams, and connections where conditioned air is escaping
- Patching damaged sections: Holes and tears in flex duct or sheet metal ductwork are patched or replaced at the affected section
- Reconnecting separated ducts: Disconnected joints and collapsed ductwork are re-secured at plenum connections and throughout the run
- Restoring duct insulation: Damaged or missing insulation is repaired or replaced to meet current standards for ducts routed outside conditioned space
Once repairs are complete, we verify airflow at the registers and confirm the system is performing as it should before we close out the job.
Repair or Replace: How to Tell the Difference
Most duct problems don’t require a full system replacement. Isolated leaks, a few disconnected joints, or a single collapsed section are all situations where targeted repair is the right answer. It can cost less and restore performance quickly.
Full replacement can make more sense when damage is widespread throughout the system, when duct materials have broken down across multiple runs, or when the existing layout can’t adequately serve the home’s current heating and cooling load. Our inspection is designed to give you an honest assessment of which situation you’re in before any work begins.
Austin Energy Code Requirements for Duct Systems
Austin’s residential energy code sets specific standards for duct performance that apply whenever ductwork is repaired or re-insulated. Duct systems must be pressure tested for air leakage, with post-construction leakage limited to 4.0 CFM per 100 square feet of conditioned floor area. That’s a measurable threshold, not an estimate, which is why pressure testing is a standard part of how we assess duct condition.
The code also sets minimum insulation requirements for ducts located outside conditioned space. Larger ducts must be insulated to at least R-8; smaller branch ducts require a minimum of R-6. Duct insulation R-value describes how well insulation resists heat transfer: the higher the number, the better the thermal resistance. When attic ductwork insulation is damaged or missing, replacing it to meet these minimums is part of restoring the duct system to code-compliant condition.
