A central AC unit in Hutchinson County spends most of the year sitting idle, then gets called on hard the moment summer arrives. Homes in Hutchinson County, SD run cooling about three months a year, from June through August. That idle stretch is not kind to the capacitor or the contactor. Both components degrade through the start-stop cycling at season's edge as much as through sustained runtime, and after a long off period they are the first to fail on a hot June afternoon. A contractor diagnosing a no-cool call here checks those two parts before anything else.
Ductwork in a house this old was put in for whatever ran first, and central AC repair surfaces that history fast. Half the homes in Hutchinson County, South Dakota were built in 1962 or earlier (2020-2024 ACS 5-year). A unit pulled apart here often shows field modifications layered over the original runs, patches at junctions where an older system met a newer one, and sealants that have long since separated. Whether the parts a failed component takes are still in production is a separate question a contractor has to answer before the repair scope is set.
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 is where heat pulled from inside the home gets released. The indoor air handler or furnace sits in a mechanical room, basement, or attic and pushes conditioned air through the house. When either stops doing its job, a contractor starts here.
The evaporator coil sits directly above the air handler and is where the refrigerant does its work on the air passing through. A refrigerant line set runs between the indoor and outdoor units, and the system also includes a metering device and a contactor that control flow and electrical switching. These are the components a contractor works through when tracing a fault.
The drawing shows a typical central AC layout, and a licensed contractor determines which components apply to your specific setup.

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.
