A Central AC compressor in Power County spends most of the calendar sitting idle, and sitting idle is its own kind of stress. Homes in Power County, ID run cooling in a single month of the year, July. Contactor contacts corrode between runs, capacitor charge leaks off over months of inactivity, and refrigerant can migrate to the compressor when it sits cold. When a homeowner switches the system on in July and nothing happens, the fault usually predates that first start by a long stretch. A contractor diagnosing the failure checks those dormant-season failure points before assuming the compressor simply wore out.
Ductwork in a house this old has already been adapted at least once, and the equipment running in it now is almost certainly not what was there originally. Half the homes in Power County, Idaho were built in 1975 or earlier (2020-2024 ACS 5-year). That gap between the building and the current system is where a repair gets complicated: the unit a contractor opens may take components that have been discontinued, and confirming what is actually inside before ordering parts is what separates a repair that closes in one visit from one that stalls waiting on a specialty supplier.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it holds the compressor and condenser coil. These are the pieces a contractor reaches first when the system stops cooling, runs loud, or trips a breaker. The compressor is often where a diagnosis begins.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower fan. The evaporator coil pulls heat out of the indoor air, and the blower pushes that air through the home. The refrigerant lines that run between the two units and the expansion valve that meters refrigerant flow are also points a contractor checks when the coil ices over or cooling falls short.
The drawing shows the general layout of a central AC system, and a licensed contractor determines what applies to your specific home and equipment.

What the repair work looks like in Power County
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.
