Ductwork Repair & Replacement in Lago Vista, TX

Most Lago Vista homeowners don't know their ducts are leaking. The average Central Texas home loses 20–30% of conditioned air through duct leaks before it reaches living spaces — air that you've already paid to cool or heat, escaping into attics and wall cavities instead of your rooms.

Leaky ductwork shows up as uneven temperatures between rooms, high energy bills, a system that runs constantly without achieving setpoint, and excessive dust. We diagnose and repair ductwork leaks across Lago Vista and Travis County — from simple duct sealing on accessible sections to full ductwork replacement in attics and crawl spaces.

Ductwork is the distribution network that carries conditioned air from your air handler to every room in the house. In most Lago Vista homes built before 2000, ductwork runs through unconditioned attic space — which means any leak is losing conditioned air into a space that can reach 140°F in summer.

Duct leaks occur at joints, connections, and seams — especially where flex duct connects to metal plenums or register boots. Over time, the mastic or tape used to seal these connections dries out, cracks, and separates. The result is a system that works harder, costs more to operate, and delivers less comfort.

We diagnose duct leakage accurately before recommending repairs. We don't replace ductwork that can be effectively sealed. For full replacements, we use properly sized ductwork — not just the same size as what came out. All work is permitted where required.
