A contractor called out for a Central AC repair in Mingo County has to sort out what actually wore the system down. 85 severe weather events were recorded in Mingo County, West Virginia between 2015 and 2024. That puts some weather load on every system in the county, but at that rate it sits alongside age, installation quality, and how consistently the unit has been serviced rather than above them. A compressor that has run for years through interrupted maintenance will fail for reasons a contractor can find and price without looking to the weather. The refrigerant lines, the capacitor, and the contactor all tell that story when a technician opens the unit.
Ductwork adapted for a system it was never designed to carry shows its seams when something goes wrong. Half the homes in Mingo County, West Virginia were built in 1982 or earlier (2020-2024 ACS 5-year). That history matters for repair work because a contractor opening a system here has to account for what the ducts around it are doing, not just the unit itself. A refrigerant problem or a failed capacitor is a straightforward fix. A repair complicated by duct connections that were improvised at some point along the way takes longer to diagnose and longer to price accurately.
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 condenser coil. These are where a contractor starts. A compressor that has seized or a coil that is fouled can stop the whole system cold, so both get close attention early in a diagnosis.
Inside the house, the air handler holds the evaporator coil and the blower fan, typically in a basement, closet, or attic. The expansion valve and refrigerant lines connect the two units. A refrigerant leak, a frozen evaporator coil, or a failing blower motor will each show up in a different way, and a contractor reads those signs to narrow down where the fault actually is.
The drawing shows a typical layout, and a licensed contractor determines what applies to the specific equipment and configuration in your 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.
