Sizing a central AC system for this area starts with knowing exactly what the compressor is being asked to do each year. Homes in Geary County, KS run cooling about four months a year, from June through September. The compressor, the condenser fan, and the contactor all cycle together every time the system cools the house, and they do it repeatedly across a concentrated stretch of summer heat. A contractor working up a load calculation here has to account for that sustained demand, because a system that is undersized or loses efficiency early will run longer cycles, which accelerates wear on the very parts doing the work. The install quality sets how well those parts hold up.
Ductwork sized and routed for an older generation of equipment is what a contractor runs into across much of this county's housing stock. Half the homes in Geary County, Kansas were built in 1987 or earlier (2020-2024 ACS 5-year). When the system being replaced ran at a different capacity than what a new unit delivers, the existing trunk lines and branch runs reflect that, and a contractor has to assess whether they carry the new equipment's airflow before anything else gets priced. The electrical service in houses of this vintage carries similar questions about whether it was sized for the draw a modern central AC unit requires.
What a Central AC Installation Puts in Your Home
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and holds the compressor and the coil that release heat to the outside air. Inside, the air handler or furnace cabinet occupies a closet, basement, or utility space and pushes conditioned air through the home.
The evaporator coil mounts directly above the air handler and is where the air gives up its heat before moving into the supply ducts. A copper refrigerant line set runs between the indoor and outdoor units, and a condensate drain line carries moisture away from the evaporator coil to a floor drain or outside.
The drawing shows the general layout of a central AC system, and a licensed contractor determines exactly what applies to your house.

What happens when the contractor shows up
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.
Severe Weather History in Geary County
Kansas weather puts real load on cooling equipment, and what happens in Geary County shapes what a system here has to handle year after year. Sizing and installing central AC without accounting for local conditions means the equipment is built for somewhere else.
