Takes about a minute. No obligation.
Before a contractor can tell you what failed in your central AC and what it will cost to fix, they have to work out what put it there. 112 severe weather events were recorded in Hampshire County, West Virginia between 2015 and 2024. At that rate, storm load is a real variable in how components age, and a contractor working a repair here checks for it before landing on a cause. Refrigerant lines, capacitors, and contactors all carry that accumulated load. A diagnosis that skips that step can misread a worn part as a simple replacement when the underlying stress is still present.
Ductwork and refrigerant lines in a house this old were put in for a specific system, and that system has had a long time to wear. Half the homes in Hampshire County, West Virginia were built in 1986 or earlier (2020-2024 ACS 5-year). When a compressor or a control board finally fails in stock like this, the question a contractor has to answer is whether the replacement part is still being made, or whether what is available now fits what the rest of the system takes. If the part is discontinued, the repair scope changes in ways that a visual inspection before opening the unit cannot predict.
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 is where heat gets shed to the outside air. The compressor lives inside that cabinet and is the part contractors look at early when a system runs but does not cool. A failed compressor or a refrigerant leak at the condenser are two of the more common reasons a central AC stops doing its job.
Inside the house, the air handler or furnace cabinet holds the evaporator coil, which is the piece that actually pulls heat out of the indoor air. A clogged or frozen evaporator coil is a frequent culprit when airflow drops or cooling becomes uneven. The refrigerant lines running between the two units and the expansion valve that regulates refrigerant flow are also points a contractor will check when the system is underperforming.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to your specific house and situation.

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.
Licensing and Legal Requirements in Hampshire County, West Virginia
West Virginia requires a licence from the Commissioner of Labor to perform, or offer to perform, work on a heating, ventilating and cooling system.
Severe Weather Events in Hampshire County
Storms put a hard load on cooling equipment: power surges, extended run times, and heat spikes that follow outages all push a system toward failure. How often that pressure arrives in Hampshire County shapes how much repair work local central AC units actually see.
