Takes about a minute. No obligation.
Homes in Shawnee County, KS run cooling about four months a year, from June through September. The compressor starts and stops repeatedly across those months, and that cycling load is where wear concentrates. Contactors pit, capacitors weaken, and condenser fan motors run hot in Kansas summers. A contractor diagnosing a central AC unit here checks those parts before anything else, because the season's accumulated starts are what surface the fault, not age on the refrigerant lines or a cabinet that's been sitting outside.
Ductwork and wiring in a house tell one story. The opened compressor or evaporator coil tells another. Half the homes in Shawnee County, Kansas were built in 1972 or earlier (2020-2024 ACS 5-year). That median puts a large share of the county's homes in the range where a system has already been replaced once or more, and the components a contractor pulls out today may belong to a product line the manufacturer has discontinued or thinned out. A repair that starts as a capacitor swap can stall at a condenser fan motor or a control board that takes real sourcing to find.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it is where heat gets shed to the outside air. The compressor lives inside that cabinet and is often the first thing a contractor tests when the system runs but produces no cooling. The refrigerant lines running between that cabinet and the inside of the house are checked alongside it.
The air handler or furnace sits inside, typically in a basement, closet, or attic, and it holds the evaporator coil, which is a frequent source of problems when airflow drops or ice forms on the unit. The expansion valve and the blower motor are part of that same interior assembly, and both are on the contractor's list when symptoms point indoors rather than out.
The drawing shows a typical layout, and a licensed contractor will determine which components and conditions apply to your specific home.

What happens when a 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.
