Takes about a minute. No obligation.
A contractor called out for central AC repair in McDowell County spends most of their diagnostic time on the system itself: how old the components are, whether the original install was sized and sealed correctly, and what maintenance has or has not happened. 87 severe weather events were recorded in McDowell County, West Virginia between 2015 and 2024. At that rate, severe weather is a real but occasional factor in a system's working life, not a standing load that wears equipment down season after season. A compressor that has failed here, or a coil that has given out, is far more likely to trace back to age or a poor original install than to storm exposure.
Ductwork and wiring adapted across equipment generations carry their history quietly, and it only becomes visible once a unit is open. Half the homes in McDowell County, West Virginia were built in 1958 or earlier (2020-2024 ACS 5-year). A central AC system running in a house that old has almost certainly outlasted at least one predecessor, and the parts it takes may be narrow or discontinued. What a contractor finds inside the cabinet, and whether those components are still in production, is what sets the scope and the price of the repair.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit, which sits on a pad beside the house, holds the compressor and condenser coil. These are where the system sheds heat, and when a repair call comes in, the compressor and the coil are among the first places a contractor looks. A failed compressor or a coil clogged with debris will stop the system cold.
Inside the house, the air handler houses the evaporator coil and the blower. The evaporator coil absorbs heat from the air moving through it, and the blower pushes that air through the home. The expansion valve, which sits between the two coils and controls refrigerant flow, and the refrigerant lines that run between the indoor and outdoor units, are also common targets when a system is cooling poorly or not at all.
The drawing shows a typical central AC layout, and a licensed contractor will determine which components apply to the specific system and conditions in your home.

What HVAC Repair Looks Like in McDowell 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.
