Takes about a minute. No obligation.
The compressor in a central AC unit starts and stops on every cooling call, and the contactor that triggers each start wears a little more each time. Homes in Wyandotte County, KS run cooling about four months a year, from June through September. A contractor pulling a failed unit here checks the compressor windings and the contactor contacts early, because those are the parts that absorb the starting load across a full season. Capacitors go the same way. Refrigerant leaks and coil fouling matter too, but the repair history of a system in this county tends to trace back to the parts that cycle hardest.
Ductwork in a house this old has absorbed decades of pressure, patching, and whatever previous owners decided to do between service calls. Half the homes in Wyandotte County, Kansas were built in 1962 or earlier (2020-2024 ACS 5-year). When a contractor opens the unit on a repair job here, the question that shapes the bill is whether the failed component is still in production, and for systems that have been running since a previous replacement cycle, that answer is not always yes. A part that a supplier can order the same week is a different repair from one that requires a workaround or a sourced substitute.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and it carries the compressor and the condenser coil. These are the parts a contractor reaches first when a system stops cooling, runs but blows warm air, or shuts off on its own. A failed compressor or a damaged coil will show up here.
Inside the house, the air handler holds the evaporator coil and the blower. The air handler is typically in a closet, attic, or utility room, and it works alongside the expansion valve and the refrigerant lines that run between the two units. Problems with refrigerant pressure, a frozen coil, or a blower that is not moving air all trace back to this part of the system.

What happens when the contractor comes out
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 Wyandotte County
Extreme weather puts real stress on central AC equipment, pushing it harder and shortening the window before something needs attention. How much of that load a system carries depends on where it runs, which is why local weather history belongs on a page about repair work in this area.
