A repair call here asks a contractor to work out what the equipment has actually been up against. 121 severe weather events were recorded in Shenandoah County, Virginia between 2015 and 2024. At that rate, severe weather is a standing condition of operating in this county, not an occasional event, and a system that has run through it carries wear in predictable places: capacitors, contactors, and refrigerant lines all absorb the load before the compressor does. When a compressor fails, a contractor who skips checking those upstream components first will miss whether the failure was driven by accumulated stress or by the compressor's own age. Those are different repairs with different part lists.
Ductwork and refrigerant lines in a house age alongside the system they serve, and in Shenandoah County the systems running in older homes often carry parts that manufacturers stopped making years back. Half the homes in Shenandoah County, Virginia were built in 1983 or earlier (2020-2024 ACS 5-year). When a contractor opens a compressor or an air handler in stock like this, the question is whether the failed component can be sourced at all, not simply what it costs. A repair that looks straightforward on the outside can stall on a part that takes weeks to locate or has no current substitute, which changes what the contractor recommends and what the homeowner is deciding between.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits on a pad beside the house and holds the compressor, the condenser coil, and the fan that pushes heat out. These are the pieces a contractor reaches first, because a failed compressor, a dirty or damaged coil, or a seized fan motor each stops the system cold. Inside, the air handler or furnace cabinet houses the evaporator coil, which is where the cooling actually happens, along with the blower that pulls air across it.
The refrigerant lines run between the two units, and a leak anywhere along them means the system loses its ability to cool. The expansion valve, the capacitors, and the contactor all sit within those same two cabinets and are common failure points a contractor checks when the system runs but does not cool, short-cycles, or will not start.
The drawing shows a typical layout, and a licensed contractor will determine which components apply to your specific system and what work each one actually needs.

What the repair visit actually looks like
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.
