A contractor quoting a central AC repair in DeWitt County has to decide, before anything else, whether the weather is actually responsible for what failed. 22 severe weather events were recorded in DeWitt County, Texas between 2015 and 2024. At that rate, severe weather is an event in this county rather than a condition, which means most systems here have spent the bulk of their lives running against heat and age, not storm load. A compressor that has given out, a coil that is leaking, a capacitor that has failed: the contractor will look at installation quality and service history before they look at the weather. Those are the variables that decide the scope and the bill.
Half the homes in DeWitt County, Texas were built in 1978 or earlier (2020-2024 ACS 5-year). A house that old was not wired or ducted for whatever system is running in it today, but that backstory is an installation question. On a repair call, what settles the job is what comes into view once the unit is open: whether the compressor, capacitor, or control board that failed belongs to a line still supported by parts suppliers, or to one that has been discontinued. Stock this age carries systems acquired across a long spread of years, and a unit installed well after the house was built can still be old enough that its parts require sourcing rather than ordering. That is what a repair estimate here has to account for before a price means anything.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along a wall or at the side of the home. It holds the compressor and the condenser coil, and those two components are where a contractor looks first when a system stops cooling. The compressor is the most common source of a dead system; a failed condenser fan motor or a dirty, bent coil will also shut cooling down.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower. The evaporator coil is a frequent culprit when a system runs but the air stays warm, and a frozen coil or a clogged drain line beneath it will often point the contractor straight to this cabinet. The refrigerant lines that run between the two units and the expansion valve that controls refrigerant flow are also on the inspection list.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific home and system.

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.
