A contractor pulling a repair call on a central AC unit in Atascosa County has to work out why the system failed before anything else gets priced. 39 severe weather events were recorded in Atascosa County, Texas between 2015 and 2024. At that rate, severe weather is an occasional fact of life here, not a standing load that grinds through components season after season. What that means for repair work is direct: the weather is seldom the reason a compressor is done or a coil has given out. Contractors look first at how old the equipment is and how well it has been maintained, because those are what the failure record here reflects.
Parts availability decides how a central AC repair goes here more often than the condition of the house does. Half the homes in Atascosa County, Texas were built in 1993 or earlier (2020-2024 ACS 5-year). A house built then may be on its second or third system, and what a contractor finds once the unit is open carries its own timeline, separate from anything stamped on the permit. If a refrigerant line or a control board has gone out of production, the repair scope changes before the house becomes relevant at all.
The Parts of a Central AC a Contractor Checks During a Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it holds the compressor and condenser coil. These are the parts a contractor reaches first. When either one fails, the system runs but produces no cooling, or shuts off entirely.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower fan, typically in a utility closet, attic, or basement. The refrigerant lines run between the two cabinets, and the thermostat on the wall tells the whole system when to run. A fault in any of these can produce the same symptom as a failed compressor, which is why a contractor works through each one before settling on a diagnosis.
The drawing shows a representative layout, and a licensed contractor determines what applies to your specific system and home.

What happens when a contractor comes out to repair your HVAC
Split-system central air conditioners rated below 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners rated at or above 45,000 Btu/h manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Split-system central air conditioners manufactured between January 1, 2015 and December 31, 2022 had to meet 13 SEER, the metric that preceded SEER2.
Single-package central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 13.4 SEER2.
Space-constrained central air conditioners manufactured on or after January 1, 2023 must meet a federal minimum of 11.7 SEER2.
Federal efficiency standards for split-system central air conditioners and heat pumps are set on each certified combination of outdoor unit and indoor coil rather than on the outdoor unit alone.
Residential and light commercial air conditioning and heat pump systems assembled in the field, including mini-splits and unitary systems, may not be installed on or after January 1, 2025 using a refrigerant with a global warming potential above 700.
A field-assembled system whose specified components were all manufactured or imported before January 1, 2025 carries no installation compliance date under the refrigerant restrictions and may still be installed.
