The compressor in a central AC unit takes its hardest abuse at startup and shutdown, not at steady run. Homes in Tripp County, SD run cooling about three months a year, from June through August. A system that has cycled through every one of those summers without a tune-up shows that history in the contactor points, the capacitor, and the compressor windings. A contractor called out for a repair here checks those components before anything else, because the load falls on them every time the unit kicks on against a hot afternoon, and they fail in a pattern this season produces reliably.
Ductwork laid down for systems that no longer exist does not announce itself from the outside. Half the homes in Tripp County, South Dakota were built in 1969 or earlier (2020-2024 ACS 5-year). A contractor opening a central AC unit in a house from that era frequently finds components whose replacement parts sit in shrinking supply chains, and what seemed like a capacitor swap or a refrigerant check can widen once the system is open. The age of the stock is the reason a repair scope here stays provisional until the unit is apart.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside or behind it, and it carries the compressor and the condenser coil. These are the pieces a contractor reaches first when a system stops cooling, runs loud, or trips a breaker. The air handler, or furnace with a coil mounted above it, sits inside, most often in a closet, basement, or attic.
The evaporator coil rides on top of or inside the air handler and is where the air actually gets cold before it moves into the ducts. The refrigerant line set, a pair of copper pipes running between the indoor and outdoor units, carries refrigerant back and forth between the two sides. The thermostat on the wall controls the whole sequence and is often the first thing a contractor checks before touching anything else.
The drawing shows a typical layout, and a licensed contractor will assess which components and conditions apply to this particular 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.
