Sizing and installation quality matter more in a county where the cooling equipment runs hard every summer. Homes in Stafford County, KS run cooling about four months a year, from June through September. The compressor, condenser fan, and contactor start and stop through every one of those months, and parts installed with loose refrigerant charge or undersized ductwork carry that stress from the first season forward. A contractor quoting a new system here has to calculate the actual load the house places on equipment, because an undersized unit runs longer cycles and wears its moving parts faster than a correctly sized one would.
Ductwork laid out for an earlier generation of equipment shapes what any new central AC installation runs into here. Half the homes in Stafford County, Kansas were built in 1951 or earlier (2020-2024 ACS 5-year). That puts a contractor's first real question on the existing duct network: whether its layout, sizing, and condition will carry what a new system requires, or whether portions of it need to be reworked before a unit goes in. The electrical follows the same logic. A service panel in a house of this vintage was sized for a load smaller than a modern central AC unit draws, and that gap shows up in the quote.
What a Central AC System Includes
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, the two components that do the heaviest work in the system. Inside, the air handler or furnace-mounted evaporator coil lives in a closet, attic, or mechanical room and is where cooled air enters the home's circulation.
The refrigerant line set runs between those two units through an exterior wall, carrying the refrigerant that links the indoor and outdoor sides. A thermostat on an interior wall is the control point, and a condensate drain line carries moisture pulled from the indoor air out to a floor drain or exterior outlet.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the conditions in your house.

What the installation 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.
