A contractor quoting a central AC installation in Reno County has to size the system for a compressor that will spend real months cycling, not occasional ones. Homes in Reno County, KS run cooling about four months a year, from June through September. The contactor and condenser fan take that load every summer, and an undersized or poorly commissioned system stresses those components from its first season. A load calculation done right accounts for the house's envelope, the ductwork already in the walls, and what the equipment will actually be asked to deliver once the heat sets in.
Ductwork in a house this old was laid out for equipment that is long gone. What a new central AC unit actually needs from that existing infrastructure, in terms of airflow path and return capacity, is the first thing a contractor has to establish before anything else on the job makes sense. Half the homes in Reno County, Kansas were built in 1962 or earlier (2020-2024 ACS 5-year). That means the duct layout gets measured and assessed before the equipment is even selected, because a system sized correctly for the house can still underperform if the paths carrying the air were designed around something different.
What a Central AC System Includes
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and is the piece most homeowners recognize on sight. Inside, the air handler or furnace-mounted evaporator coil sits in a utility space, basement, or closet, and is the indoor half of the system that conditions the air before it moves through the house.
The refrigerant line set runs between the two units, connecting the outdoor and indoor sides through a small penetration in the wall. A thermostat on an interior wall is the control point, and an electrical disconnect mounted near the condenser is part of what a contractor ties into when the system goes in.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this 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.
