Sizing and refrigerant charge matter more here than a contractor working a milder county might assume. Homes in Pratt County, KS run cooling about four months a year, from June through September. The compressor cycles through that entire stretch, starting and stopping as temperatures climb, and an undersized unit runs longer per cycle and builds heat stress on the contactor and condenser fan faster than the calendar alone would suggest. A contractor quoting a new system here works out the load calculation first, because an install that leaves the compressor short on capacity will show the gap in the components that bear the burden of every hot afternoon.
Ductwork laid out for older, lower-capacity equipment often cannot move the air volume a modern central AC system requires, and what a contractor finds inside the walls decides the scope before the unit itself is ever priced. Half the homes in Pratt County, Kansas were built in 1956 or earlier (2020-2024 ACS 5-year). That depth of housing history means the existing duct runs are a genuine unknown on many jobs: the sizing, the routing, and the condition of what is already there. A contractor who skips a duct assessment before quoting a new system is pricing the wrong thing.
What a Central AC Installation Covers
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and holds the compressor and the condenser coil. Inside, the air handler or furnace with an evaporator coil sits in a utility space, basement, or closet and is the piece that conditions the air before it moves through the house.
The refrigerant line set runs between those two units, connecting the indoor and outdoor sides through a small penetration in the wall. A thermostat goes on an interior wall where the homeowner sets and reads the temperature, and the condensate drain line carries moisture from the evaporator coil to a floor drain or outside.
The drawing shows a typical layout, and a licensed contractor determines what applies to this particular house.

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.
