The U.S. Department of Energy estimates that the average home loses 20–30% of conditioned air through leaks, gaps, and disconnections in the duct system—a staggering efficiency loss that's especially costly during Austin's long cooling season. William & Sons Austin Air Duct Cleaning identifies and repairs common duct defects including disconnected flex duct joints, torn duct liner, collapsed sections, loose plenum connections, and improperly seated register boots. We use mastic sealant, foil-backed tape rated for HVAC use, and metal sheet patches as appropriate for each repair type, following best-practice installation standards for durable, airtight results.
Before performing repairs, we conduct a visual inspection of accessible ductwork—in attics, crawl spaces, and mechanical rooms—to document all problem areas. For homes with significant suspected leakage that isn't visually obvious, we can discuss third-party blower door and duct blaster testing options with partner contractors. Sealing duct leaks in the attic is particularly impactful in Austin homes because attic temperatures can exceed 140°F in summer; any conditioned air escaping into the attic rather than reaching your living rooms is both comfort and money lost.
Duct repair pairs naturally with duct cleaning, since cleaning reveals damaged sections that might otherwise go unnoticed. After sealing, most homeowners notice more even room temperatures, better humidity control, and reduced HVAC runtime—tangible improvements in both comfort and energy efficiency that pay back the investment quickly in Austin's climate.

Common Questions
How can I tell if my ducts are leaking?
Common indicators include rooms that never seem to reach the set temperature, unusually high energy bills, excessive dust on surfaces (indicating attic or crawl-space air is being pulled into the system), or visibly disconnected duct sections you can see in the attic or mechanical room.
Is foil HVAC tape the same as regular duct tape?
No. Standard gray cloth duct tape is actually not rated for HVAC duct applications and degrades quickly with heat cycling. We use UL 181-rated foil-backed tape and mastic sealant, both of which are specifically designed for long-term, airtight duct sealing.
