A contractor called out to repair a central AC system in Live Oak County will ask how old the system is and how consistently it has been serviced, because those two facts explain most of what they find. 40 severe weather events were recorded in Live Oak County, Texas between 2015 and 2024. At that rate, severe weather is an occasional event here rather than a grinding constant, which means a failing compressor or a burned contactor points toward years of hard summer use and deferred service rather than storm wear. The electrical connections, the refrigerant charge, and the condition of the capacitor are where a diagnosis starts.
Ductwork and wiring in houses this old have already outlasted at least one set of equipment, which means the system running today was fitted into whatever was already there. Half the homes in Live Oak County, Texas were built in 1985 or earlier (2020-2024 ACS 5-year). A repair call here lands a contractor at a unit whose internals reflect that history: what seals and contacts and capacitors actually look like once the panels come off depends on how many hands have been inside it and what they used. Parts for older systems still exist, but availability varies enough that a contractor confirms what the unit takes before pricing the job.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually beside the foundation, and it is where the system sheds heat to the air around it. The indoor air handler or furnace sits inside, often in a utility closet, attic, or basement, and it is the piece that moves air through the house. When a system stops cooling or starts behaving oddly, these two units are where a contractor begins.
The refrigerant line set runs between the two units, carrying refrigerant back and forth, and a fault there can make both units look fine while the system fails to cool. The expansion valve, the evaporator coil inside the air handler, and the condenser coil outside each play a role in that exchange, and any one of them is a potential source of a breakdown that does not announce itself clearly from the outside.
The drawing shows a typical layout, and a licensed contractor determines which components apply and what needs attention in your specific home.

What the repair visit looks like
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.
