A contractor called out for a Central AC repair in Delta County has to settle one question before pricing anything: what actually wore this system down. 20 severe weather events were recorded in Delta County, Texas between 2015 and 2024. At that rate, severe weather has touched most equipment here only occasionally, so it rarely accounts for a failed compressor or a refrigerant problem. What a contractor finds in an opened unit is more likely tied to how old the system is, how well it was installed, and whether it has been serviced. Those are the places the repair scope gets decided.
Ductwork and electrical service in these houses were configured for whatever ran in them originally, then adapted as systems were swapped over the years. Half the homes in Delta County, Texas were built in 1980 or earlier (2020-2024 ACS 5-year). That gap between the building and the equipment inside it means a repair call here usually comes down to what the opened unit actually contains: a failed capacitor, a compressor drawing more than it should, a refrigerant circuit that has been leaking slowly. Parts availability on equipment installed long after the house was built is a real question, and a contractor checking model and serial numbers before quoting a repair is doing that because some components on mid-vintage systems are no longer stocked by distributors.
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 carries the compressor and the condenser coil. These are where a contractor looks when the system runs but produces no cooling, when it short-cycles, or when it trips the breaker.
Inside the house, the air handler holds the evaporator coil and the blower. The evaporator coil is a common source of trouble when the system freezes over or when airflow drops sharply. The blower motor and the capacitor that starts it are frequent repair points when the fan runs poorly or not at all.
The drawing shows a typical layout, and a licensed contractor determines which components apply to the specific system in your home.

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.
