A contractor diagnosing a central AC repair in Lampasas County starts with the equipment, not the weather. 46 severe weather events were recorded in Lampasas County, Texas between 2015 and 2024. At that rate, severe weather touches a system rarely enough that age, refrigerant state, and installation quality are the likeliest explanations for what broke. A compressor that has given out here most likely ran too long on degraded refrigerant or was improperly sized from the start. The weather record belongs in the background of a diagnosis, not at the center of it.
Ductwork and refrigerant lines in a house this old were sized and routed for whatever system was running at the time, which means the equipment a contractor opens today is rarely the first thing to occupy that space. Half the homes in Lampasas County, Texas were built in 1990 or earlier (2020-2024 ACS 5-year). When a compressor or a coil comes apart on a system running in stock like this, the question a contractor has to answer on the spot is whether the part it needs is still being made. Manufacturers phase out components on schedules tied to production runs, and a system serving a house of this vintage can sit right at that boundary.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and it carries the compressor and the condenser coil. Those two components are where contractors start when a system stops cooling, because a failed compressor or a fouled coil stops the whole system cold. The air handler or furnace cabinet lives inside, typically in a closet, attic, or utility room, and it holds the evaporator coil and the blower.
The refrigerant lines run between the indoor and outdoor units, and a leak anywhere along them shows up as poor cooling before anything else fails visibly. The expansion valve, which sits at the evaporator coil, controls how refrigerant moves into that coil, and a stuck or failed valve will mimic the symptoms of a refrigerant shortage. The thermostat on the interior wall is the last piece a contractor checks, because a wiring fault or a failing sensor there can make a perfectly functional system behave as if it is broken.
The drawing shows a general layout of how these components relate to one another, and a licensed contractor determines what applies to your specific house and system.

What happens once a contractor shows up
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.
