Quick Answers: HVAC in North Texas
Why do North Texas attics wreck duct efficiency?
Most North Texas homes run their supply ducts through an unconditioned attic that hits 130-150°F on a July afternoon. Every gap, crushed flex run, or unsealed boot lets that superheated attic air mix into the conditioned air before it reaches your registers, so the system loses cooling capacity exactly when you need it most. Sealing the boots, plenum connections, and flex-to-collar joints, then verifying R-8 wrap, is the single highest-return duct fix in this climate.
Mastic or foil tape for sealing ducts?
For a permanent seal we brush on water-based duct mastic, not tape. Standard cloth-backed duct tape dries out and lets go within a few Texas summers; even UL-181 foil tape struggles on dusty flex collars in a hot attic. Mastic (often with mesh tape over larger gaps) stays flexible, bonds to sheet metal and flex alike, and is what gets you a lasting reduction in measured leakage.
Should I seal or replace my flex ducts?
It depends on what the inspection finds. Sealed leaks at boots, collars, and the plenum can usually be fixed in place with mastic. But kinked, crushed, torn, or sagging flex runs with high static pressure restrict airflow no matter how well they are sealed, so those sections get replaced and re-supported. We measure static pressure and leakage first, then tell you which approach actually solves your hot-room problem.
Attic Heat Gain Is Stealing Your Cool Air
In Collin and Denton County homes, the supply trunk and flex runs almost always live in the attic, where summer temperatures climb past 130°F. A typical duct system here leaks 20-30% of its airflow at boots, plenum seams, and flex-to-collar connections, and every one of those leaks pulls in baking attic air. The result is the back bedroom that never cools, an AC that runs all afternoon, and a power bill that creeps up every July. Sealing those leaks with mastic and verifying duct insulation puts that lost capacity back where it belongs. Pair sealing with a duct cleaning or a system tune-up and the difference is immediate.
