Duct Repair & Sealing

The U.S. Department of Energy estimates that the typical home loses 20–30% of conditioned air through duct leaks — and in Austin, where your AC runs for eight or more months a year, that loss is a significant and ongoing expense. Edwards Air Duct Cleaning inspects your duct system for disconnected flex duct joints, torn inner liners, crushed sections, unsealed takeoffs, and gaps at plenums or air handler connections, then repairs and seals problem areas using mastic sealant, metal-foil tape, and duct connectors rated for residential HVAC use.

Common signs of duct leakage include uneven temperatures between rooms, rooms that never quite reach setpoint, unusually high electric bills, or visible gaps and sags in exposed attic ductwork. Flex duct in Austin attics is particularly vulnerable to damage from foot traffic during roof or HVAC work, extreme summer heat, and pest activity — all issues we commonly find and correct during our service visits.

Our duct repair service is available as a standalone visit when damage is identified during a cleaning or inspection, or as a proactive service for older homes. Properly sealed ductwork not only reduces energy waste but also prevents attic air — which may contain insulation fibers, rodent dander, and extreme heat — from being pulled into your living space through leaks in the return-air side of your system.
