A contractor quoting a central AC repair in Latah County has to account for what the system has not been doing. Homes in Latah County, ID have essentially no cooling season — no month of the year is warm enough to call for it. Compressors and contactors that sit idle for years develop their own failure modes: seals dry, lubricants settle, and the first hard start after a long off period puts stress on components that never had a chance to wear in gradually. When a unit finally does get called on and refuses to run, the fault usually traces to that dormancy, not to accumulated summer load. A contractor checking a failed compressor here looks at how long it has sat and how many cold starts it has been through.
Half the homes in Latah County, Idaho were built in 1980 or earlier (2020-2024 ACS 5-year). A house that old has almost certainly swapped its original cooling equipment at least once, and what sits in it now may be a generation removed from anything the ducts were set up for. When a contractor opens a unit, the real question is whether the parts it needs still exist. Compressor models cycle out, control boards get discontinued, and refrigerant specifications change. If the repair requires a component that is no longer manufactured, the scope of the job changes before a quote can be written.
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 carries the compressor and the condenser coil. Those two components do the heaviest work in the system, so when the unit runs but the house stays warm, or trips a breaker, or makes noise it did not used to make, a contractor starts here.
Inside the house, the air handler holds the evaporator coil and the blower fan, and it is typically mounted in a utility closet, attic, or basement. The expansion valve and refrigerant lines tie the two units together, and a failed valve or a low refrigerant charge can stop cooling even when both units appear to be running fine.
The drawing shows a representative layout of these components, and a licensed contractor determines which parts apply and what condition they are in for your specific home.

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.
