HVAC in Austin spends months rejecting brutal heat and then gets one night to prove it can heat. Attic ducts and air handlers sit in temperatures that punish equipment. West glass makes the load worse in the afternoon. When the freeze comes, a heat pump, electric strips, or a furnace that has not run since last time is a stranger, and condensate lines that lived in the attic all summer can freeze and then flood the ceiling on the thaw.
Cooling complaints here are usually airflow, a tired capacitor, or a condenser that cannot breathe in the peak heat. A filter left too long and a return leaking attic air will make any unit feel finished. Say if the upstairs cooks while a room near the handler is icy. That is balance, and it shows up in two-story houses and in bungalows with added rooms. Do not skip the drain. A pan full of growth overflows on the hottest week, which is most of the summer.
The freeze night is its own ticket. No heat means power, thermostat, strips, or a furnace that failed when it was finally asked to work. A wet ceiling the next morning under the attic unit often means the condensate trap froze, not a sudden roof hole. Say which symptom you have so the visit is not aimed at the shingles. Outdoor units need clearance, and a coil matted with cottonwood cannot reject heat.
Equipment in a closet or a garage shares the house's blind spot: spaces people treat as indoors until the night they are not. Ask whether the heat source is safe to run and whether the flue or the exhaust is clear. Ask where the condensate actually terminates. If hail or a limb hit the condenser, say that separately from a heat failure. This city will hand you both in different seasons, and mixing them muddies the repair.
Give the address, where the equipment sits, and the symptom today: warm air in the heat, no heat on the freeze night, a wet ceiling after the thaw, or a system that short-cycles. Mention creek water only if it reached the pad. Ask for airflow, drainage, and a real test of the heat side. Call the number on this page.
