A compressor that has been off since late summer and starts up on the first genuinely hot day of the following July is the one most likely to show a fault. Homes in Ziebach County, SD run cooling about two months a year, from July through August. Contactors corrode during a long off-season, capacitors lose their charge-holding ability sitting dormant, and refrigerant leaks that were slow enough to miss in fall announce themselves the moment the system is asked to run hard. A contractor diagnosing a failed central AC here checks those components before anything else, because idle-season degradation is the more common culprit than accumulated runtime wear.
Ductwork in a house of this age was sized and routed for whatever system was original to the building, and that system is almost certainly not what is running today. Half the homes in Ziebach County, South Dakota were built in 1987 or earlier (2020-2024 ACS 5-year). A contractor opening a unit here may find a configuration that has been adapted more than once, with components drawn from different eras of the equipment line. Whether the failed part is still manufactured, or whether a compatible replacement exists at all, is what determines the repair scope and the bill, and that question only has an answer once the unit is open.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and it carries the compressor and condenser coil. These are the pieces a contractor looks at first when a system stops cooling or cycles oddly. Inside, the air handler or furnace houses the evaporator coil and the blower, and either of those can be the source of a refrigerant, airflow, or drainage problem.
The refrigerant lines run between the two units, and a leak anywhere along them will show up as a cooling failure even when both units appear intact. The thermostat and its wiring sit at the other end of the signal chain, and a faulty reading or a wiring fault there can mimic a much larger mechanical problem.
The drawing shows a typical layout, and a licensed contractor will assess which components apply to this particular house and system.

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.
