A contractor sizing up a central AC repair in Mineral County starts at the outdoor unit, not the thermostat. 128 severe weather events were recorded in Mineral County, West Virginia between 2015 and 2024. At that rate, the condenser coils and capacitor have been running against real weather stress for years, and those are the components that show it first. Age and maintenance still matter, but a contractor who skips the outdoor equipment before quoting a repair is missing what this area asks of a cooling system.
Ductwork and refrigerant lines in much of this county's housing stock were put in well before today's systems existed, and a repair call can expose components that have been superseded more than once since. Half the homes in Mineral County, West Virginia were built in 1977 or earlier (2020-2024 ACS 5-year). When a contractor opens a unit here, the question that shapes the repair is often whether the part the system requires is still in the supply chain at all, and if so, at what lead time. A common repair on a newer system is a parts lookup; the same fault on equipment running in a house this old can become a sourcing problem before the fix is ever scheduled.
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 houses the compressor and condenser coil. These are the pieces a contractor goes to first when the system is not cooling, because a failed compressor or a clogged or leaking condenser coil will stop the whole system cold.
Inside the house, the air handler holds the evaporator coil and the blower that moves air across it. The refrigerant line set connects the two units, running between them through the wall, and the thermostat on an interior wall is the control point that tells the system when to run. A fault in any of these can produce the same symptom at the vent, so a contractor works through each one to find the true source.
The drawing shows a typical layout, and a licensed contractor determines which parts apply and what condition they are in for your specific home.

What happens when the contractor comes out
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.

Severe Weather Events in Mineral County
Extreme weather puts real stress on central AC systems, running compressors and capacitors harder and longer than mild conditions ever would. How much stress depends on what the local climate actually delivers, which is why the record for Mineral County matters to anyone thinking about repair or maintenance.
