A contractor called out for a central AC repair here is working out how much of what they find belongs to the equipment itself and how much belongs to what the area has asked of it. 83 severe weather events were recorded in Ohio County, West Virginia between 2015 and 2024. At that rate, severe weather is a real part of the operating environment, but it sits in the background rather than dominating every diagnosis. A compressor that has reached the end of its useful life reached it through years of ordinary summer load, and that is where the repair conversation starts.

Ductwork in a house this old was sized and routed for equipment long since discontinued, and what a contractor opens inside a failing central AC unit reflects that same history. Half the homes in Ohio County, West Virginia were built in 1956 or earlier (2020-2024 ACS 5-year). A compressor or control board from a system installed in a house of that vintage may simply not have a current replacement, which turns a straightforward repair into a sourcing problem before it is anything else. The diagnosis usually comes fast; finding the part is where the job can stop.
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 components a contractor goes to first when a system stops cooling, runs constantly, or makes unusual sounds. A failed compressor or a damaged coil will stop the whole system.
Inside the house, the air handler holds the evaporator coil and the blower fan. The evaporator coil is a common source of trouble when airflow drops or the system starts freezing up. The blower fan, the refrigerant lines running between the two units, and the thermostat on the wall each get checked as part of the same diagnosis.
The drawing shows how these pieces connect in a typical installation, and a licensed contractor determines which components are involved in your house.

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 Ohio County
Weather stress accumulates inside HVAC equipment every time outdoor conditions swing hard. A unit that runs through sustained heat, cold snaps, or storm-driven power fluctuations carries more wear than one that does not, and what Ohio County sees over time shapes what local repair work looks like.
