A contractor diagnosing a failed central AC unit in Concho County starts with the system itself: how old the components are, whether the unit has been serviced, and what the refrigerant and electrical connections look like. 55 severe weather events were recorded in Concho County, Texas between 2015 and 2024. At that rate, severe weather is something equipment here encounters now and then, not a sustained grind that wears parts down ahead of schedule. A compressor that gives out in this county almost certainly gave out because of age or deferred maintenance, and a contractor scoping the repair will find the evidence of that inside the unit.
Ductwork laid down for one generation of equipment and then pressed into service for the next carries its own repair record, and a failing central AC unit here is often failing partly because of what surrounds it. Half the homes in Concho County, Texas were built in 1973 or earlier (2020-2024 ACS 5-year). That gap between when a house was framed and when its current system was installed is where a contractor spends diagnostic time: checking what the duct connections are actually doing, whether they are pulling conditioned air away from the coil cleanly, and whether the wiring feeding the unit has been extended or spliced in ways that now stress the components. The unit's parts list matters. So does what those parts are pushing against.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits on a pad beside the house and holds the compressor, the condenser coil, and the fan that pushes heat outside. These are the pieces a contractor reaches first, because a failed compressor or a clogged condenser coil will shut the whole system down. Inside, the air handler or furnace cabinet holds the evaporator coil, which is where warm indoor air gives up its heat.
The refrigerant line set runs between the two cabinets, and a fault anywhere along it affects both sides of the system. The blower motor inside the air handler moves air across the evaporator coil and into the supply plenum, and a contractor checks it alongside the capacitors and contactors that start and run the compressor and the outdoor fan.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components and conditions apply to your specific home.

What HVAC Repair Looks Like in Concho County
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.
Licensing Rules in Concho County, Texas
In Texas a person may not engage in air conditioning and refrigeration contracting unless that person holds a license issued under the state air conditioning and refrigeration contractor law.
Severe Weather Events in Concho County
Extreme weather puts hours on HVAC equipment fast, and those hours show up as wear, failures, and repair calls. How hard the weather pushes here is part of what determines how hard the equipment works.
