A contractor called out to repair a central AC unit in Marion County has to sort out what actually caused the failure before they can price the job. 73 severe weather events were recorded in Marion County, West Virginia between 2015 and 2024. At that rate, severe weather is an event in this county rather than a constant operating condition, which means a failed capacitor or a seized compressor is more likely a product of age or skipped servicing than of storm load. A contractor will check refrigerant levels, electrical contacts, and the condition of the compressor itself, because those are where deferred maintenance shows up.
Ductwork and refrigerant lines in a house built for mid-century standards have been adapted more than once to carry whatever system came next. Half the homes in Marion County, West Virginia were built in 1961 or earlier (2020-2024 ACS 5-year). When a contractor opens a central AC unit in stock like this, the question that determines the repair bill is often whether the parts that system takes are still being made, and what sourcing them costs if they are not. A worn capacitor or a failed contactor on a recent unit ships next day. The same diagnosis on a system old enough to match the house it cools can send a contractor hunting a parts chain that has moved on.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and it carries the compressor and the condenser coil. Both are frequent starting points when a system stops cooling. The air handler or furnace cabinet lives inside, typically in a utility closet, basement, or attic, and it holds the evaporator coil and the blower that moves air through the house.
The refrigerant lines run between the two units, and a leak anywhere along them will pull the whole system down. The thermostat on the wall is the first thing a contractor checks when the complaint is that the system will not respond, because a wiring fault or a failed sensor there can mimic a much larger problem.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply and what condition they are in for your specific home.

What HVAC Repair Looks Like in Marion 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.
