A contractor called out to repair a central AC system in Calhoun County has to work out what actually drove the failure before anything else. 44 severe weather events were recorded in Calhoun County, West Virginia between 2015 and 2024. At that rate, severe weather is an occasional event in a system's life, not a steady grind on its components. Compressor failures, refrigerant loss, and electrical faults here trace back to the age of the equipment and how consistently it was serviced. The storm record is part of the picture, but a contractor who leads with it is probably pointing away from the real answer.
Half the homes in Calhoun County, West Virginia were built in 1975 or earlier (2020-2024 ACS 5-year). Houses built around that time were well into their lives before central AC became common in this part of West Virginia, which means the equipment running in them now is almost certainly a later addition and has been cycled through at least once since. When a system opens up, a contractor is pricing against what the manufacturer still produces for that model, and in stock this old the answer is not always straightforward. A part that was standard a generation ago can be discontinued, substituted, or sourced only through specialty suppliers, and that changes the bill.
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 holds the compressor and condenser coil. These are where a contractor often starts when the system stops cooling, since a failed compressor or a fouled coil will shut the whole system down. The air handler or furnace cabinet inside the house holds the evaporator coil and the blower, which pulls warm air across the coil and pushes cooled air into the ducts.
The refrigerant lines run between the two units, carrying refrigerant back and forth, and a leak anywhere along them will rob the system of cooling. The expansion valve and the capacitors that start the motors are smaller components, but either can stop a working system cold. The thermostat on the wall controls all of it and is sometimes the first thing a contractor checks before anything else.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to this particular house and its setup.

What HVAC Repair Looks Like in Calhoun 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.
