Sizing a central AC system for a Beadle County home means accounting for a compressor that sits dormant the better part of the year. Homes in Beadle County, SD run cooling about three months a year, from June through August. Contactor corrosion, refrigerant leaks, and capacitor degradation can all develop during that long off period, and none of them announce themselves until the unit starts up in June. A contractor quoting a new installation here factors that idle-season failure risk into equipment selection and commissioning checks, because the first call of summer is the worst time to discover a problem the install could have prevented.
Ductwork laid down for an earlier generation of heating equipment carries assumptions about airflow and load that a new central AC system does not share. Half the homes in Beadle County, South Dakota were built in 1963 or earlier (2020-2024 ACS 5-year). A contractor quoting a central AC installation here pulls measurements from what is already in the walls and ceiling before the equipment selection starts, because duct sizing that worked for the original system can force a redesign that changes both the scope and the electrical work running alongside it. The panel, too, gets checked against what a modern unit actually draws.
The Parts of a Central AC System and What Gets Installed
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and houses the compressor and condenser coil. The indoor air handler or furnace cabinet lives inside, typically in a utility closet, attic, or basement, and holds the evaporator coil that pulls heat out of the air moving through it.
The thermostat mounts on an interior wall and is the control point for the whole system. A refrigerant line set runs between the two main units, and a condensate drain line carries moisture away from the evaporator coil to a floor drain or outside.
The drawing shows a standard layout, and a licensed contractor determines exactly how each piece fits the conditions of your home.

What the Installation Actually 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.
