Takes about a minute. No obligation.
A contractor quoting a central AC repair in Randall County has to sort out what the system has been running against before they can say what gave out and why. 390 severe weather events were recorded in Randall County, Texas between 2015 and 2024. At that rate, severe weather is a routine part of the operating life of equipment here, which means wear on the compressor, condenser coil, and electrical components reflects real cumulative load. A part that looks old may have been pushed hard. Contractors working repairs in this area check for stress-related failure before they write the system off as simply aging out.
Older Central AC systems carry a specific repair liability that newer ones do not: the parts. Half the homes in Randall County, Texas were built in 1986 or earlier (2020-2024 ACS 5-year). Equipment installed in homes of that age has cycled through at least one full replacement since the walls went up, but the units now running in those houses are old enough that contractors routinely open a system and find components whose manufacturers have discontinued the line. That is not a framing problem or a pricing problem. It decides whether a repair is even possible, or whether the job becomes a replacement the homeowner had not planned for.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it carries the compressor and condenser coil. Both are common starting points when a system stops cooling. The indoor air handler or furnace-mounted evaporator coil lives inside, typically in a closet, attic, or mechanical room, and a fault there often shows up as warm air, ice on the coil, or water around the unit.
The refrigerant lines run between those two units, and a leak anywhere along them will pull the whole system down. The thermostat sits on an interior wall and is the first thing a contractor rules out, since a wiring fault or failed sensor there can mimic a much larger problem.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply and what condition they are in for your specific home.

What HVAC Repair Looks Like in Randall 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.
