A contractor working a central AC repair in Putnam County has to settle one question before quoting anything: which components failed because of ordinary age and which ones were pushed there by accumulated weather load. 197 severe weather events were recorded in Putnam County, West Virginia between 2015 and 2024. At that rate, severe weather is a standing condition of operating here, and it shows up in what a contractor finds inside the system. Capacitors, contactors, and compressor windings that have been running hard through repeated stress cycles wear differently than ones that have simply sat idle for years. A contractor who skips that distinction replaces the wrong parts.
Central AC systems in houses this old have typically been replaced at least once since the original installation, which means what a contractor opens is not what the house came with. Half the homes in Putnam County, West Virginia were built in 1989 or earlier (2020-2024 ACS 5-year). A compressor or condenser installed years after the house was framed runs on parts whose availability depends on when that equipment was manufactured, not when the house was. So when a repair call comes in, the contractor's first question after pulling the unit apart is whether the failed component is still in production, because that answer shapes the scope and the cost of everything that follows.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits beside the house and holds the compressor, which is the part contractors reach for first when a system stops cooling. The compressor drives the whole refrigeration cycle, so when it labors or fails, nothing downstream works right. The condenser coil wraps around it and sheds heat to the outside air.
Inside the house, the air handler or furnace cabinet holds the evaporator coil, which is where the cooling actually happens at the air passing through. The refrigerant line set connects the two cabinets, running through the wall, and the expansion valve sits near the evaporator coil controlling refrigerant flow into it. The blower fan and the capacitors that start the motors are also inside these cabinets and are common repair points.
The drawing shows a typical layout, and a licensed contractor will determine which components and conditions apply to your specific home.

What to Expect From the Repair Visit
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.
