A contractor quoting a central AC repair in Midland County has to account for what the equipment has already been through before settling on a cause. 264 severe weather events were recorded in Midland County, Texas between 2015 and 2024. At that rate, severe weather is part of the normal load every system here carries across its working life, and components that bear the brunt of heat stress and pressure cycling tend to show it first. That shifts where a contractor looks early in a diagnosis: compressor condition and refrigerant-side wear get checked before softer explanations get any weight.
Half the homes in Midland County, Texas were built in 1992 or earlier (2020-2024 ACS 5-year). A house that has stood that long has not run the same air conditioner its whole life. Equipment gets replaced, and the system a contractor opens today may be a generation or two removed from what the house originally held. That gap matters for repair work because the question is whether the failed component still has a supply chain. If the part has gone obsolete, a repair becomes a replacement conversation whether the rest of the unit is sound or not.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and it sheds the heat the system pulls from inside. The indoor air handler or furnace sits in a utility closet, attic, or basement and pushes conditioned air through the home. When a repair call comes in, these are the pieces a contractor moves toward first.
The evaporator coil rides inside the air handler, above the heat source, and it is where refrigerant does its work on the air passing over it. A refrigerant line set connects the two main units, running through a wall or chase between indoors and out. The thermostat on the wall ties it all together by telling the system when to run.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to this particular house.

What HVAC Repair Looks Like in Midland 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 and Legal Requirements in Midland 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 Midland County
Extreme weather puts real stress on cooling equipment: hard starts, extended run times, and power fluctuations that wear components faster than ordinary use. How much of that load your system carries depends on what the local climate actually delivers.
