Takes about a minute. No obligation.
Homes in Trego County, KS run cooling about four months a year, from June through September. A compressor starting and stopping through a full summer puts real stress on the electrical contacts and the contactor, and by the time a system shows symptoms, those parts have already absorbed years of that cycling. A contractor diagnosing a failed unit here checks the compressor windings and the contactor before looking elsewhere, because that is where the load lands first. Refrigerant charge and coil condition follow close behind.
Older ductwork and aging refrigerant lines are what a contractor opens the job into here. Half the homes in Trego County, Kansas were built in 1963 or earlier (2020-2024 ACS 5-year). That gap between the building and the equipment now running in it means parts availability is the variable that most often decides a repair's scope. When a compressor or a control board in a system this old fails, the question of whether a matching replacement is still manufactured can push a repair in a different direction than the diagnosis suggested.
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 sheds the heat that gets pulled out of your home. The indoor air handler or furnace-based indoor coil lives inside, often in a utility closet, basement, or attic, and it is where the refrigerant absorbs that heat. These two pieces and the refrigerant line connecting them are where a contractor looks first when a system stops cooling.
The evaporator coil sits inside the air handler and is a common point of failure when airflow drops or ice starts forming on the equipment. The refrigerant lines running between the indoor and outdoor units and the expansion valve that controls refrigerant flow are also on a contractor's checklist, since a fault in either one changes how the whole system behaves.
The drawing shows a typical layout, and a licensed contractor assesses which components and conditions apply to your specific house.

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.
Severe Weather in Trego County
Weather puts load on cooling equipment. Hard summers and sudden storms push systems harder and longer, which is why local repair needs in Trego County look different from those somewhere else.
