HVAC in Dallas spends the long hot season in an attic and then gets judged on a handful of cold nights. Cooling carries the year: coils, condensers, and ducts in brutal attic heat. Hail bends fins on the outdoor unit and packs them with debris from shredded leaves. The short freeze asks a furnace or a heat pump that has been idle since the last cold morning to wake up, and many of them do not.
Airflow and drainage explain more weak cooling than a curb guess. A choked filter, a return pulling from the attic, and duct leaks into that heat will make a decent unit feel finished. Condensate lines that ran all summer can freeze on the cold night and then dump water through the ceiling when they thaw. That stain is a heating-week plumbing symptom with an air-conditioning cause. Say if the pan overflowed or the register simply blew warm.
Look at the condenser after hail before you decide the system is just old. Fins mashed flat cannot reject heat, and a cover or a coil smashed by a limb is storm damage, not a mysterious loss of cooling. Photograph it. If the system is electrically dead after the storm passed through, say whether neighbors have power and whether you have reset nothing yet. Do not turn a hail bruise on the coil into a story about the furnace, or the reverse.
Heating calls in this city are specific. The equipment may sit in a closet or, very often, in the attic above a ceiling that is about to get wet if the drain froze. Ask about the heat exchanger or the strips only after someone confirms the unit is getting power and airflow. A house that stayed warm with space heat while the real system sat will tell you the idle-heater problem in plain language. Mention that.
Give the address, where the equipment sits, and what it is doing: warm air, no air, a wet ceiling at the pan, or no heat on the cold night. Mention hail only if the outdoor unit or the power to it was hit. Ask for a visit that checks fins, drainage, and the heat side that usually sleeps. Call the number on this page.
