Sizing a central AC system in Wabaunsee County starts with what the compressor will actually be asked to do. Homes in Wabaunsee County, KS run cooling about four months a year, from June through September. That compressor starts and stops repeatedly through June, July, August, and September, and the contactor takes that cycling load directly. A unit undersized for the house runs longer each cycle to hold temperature, which accelerates wear on the condenser fan motor and shortens the contactor's service life. A contractor who skips a proper load calculation and guesses at tonnage is pricing in a callback.
Ductwork laid in for an earlier generation of equipment does not automatically carry a modern central AC system. The runs, the sizing, and the return placement were all decisions made around something else, and a contractor installing a new system has to work out whether what is already in the walls moves enough air, in the right places, for the unit being matched to the house. Half the homes in Wabaunsee County, Kansas were built in 1964 or earlier (2020-2024 ACS 5-year). That share of the housing stock means duct assessment is the part of an installation quote that can change the scope, because a layout that served the original system well may restrict airflow or require added returns before a new unit performs correctly.
What a Central AC Installation Covers
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, which are the heart of the system. Inside, the air handler or furnace-mounted evaporator coil lives in a utility space, basement, or closet and is the point where cooled air enters the home's circulation.
The refrigerant line set runs between those two units, typically along an exterior wall or through a chase, and a new thermostat goes on an interior wall where it can read the home's ambient temperature. Each of these pieces is part of what a contractor prices, sources, and places during an installation.
The drawing shows a representative layout, and a licensed contractor determines what fits the actual configuration of your 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.
Severe Weather Events in Wabaunsee County
Kansas weather puts real stress on cooling equipment, and Wabaunsee County gets its share of what the climate delivers. How hard a system has to work, and how long it holds up, is shaped by local conditions, which is why the weather record here is relevant to any installation decision.
