A contractor diagnosing a failed central AC unit in Greensville County starts with the system itself: how old it is, whether it has been serviced, and which components are showing wear. 32 severe weather events were recorded in Greensville County, Virginia between 2015 and 2024. At that rate, severe weather enters the picture sometimes, but it does not account for most compressor failures or refrigerant losses a contractor finds on a call here. A system that has been skipped on maintenance for years will fail on a mild afternoon. The weather record matters less than the service record.
Ductwork in a house this old has been patched, re-routed, and left alone in turns, and whatever refrigerant line or drain line a contractor pulls back a panel to reach carries that full history in its condition. Half the homes in Greensville County, Virginia were built in 1979 or earlier (2020-2024 ACS 5-year). That spread matters for repair work specifically because the systems running in those older houses have, in many cases, already been replaced once, and the replacement was sized and specified for the duct configuration it inherited. When a repair contractor opens the unit, the question that decides the job is whether the failed component still has a supply chain behind it, and in equipment installed into older stock that answer runs against the homeowner more often than the age of the house alone would suggest.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad at the side or rear. It holds the compressor and the condenser coil, and those two pieces are where a contractor starts. A failed compressor or a fouled coil will stop the whole system cold, so they get checked before anything else.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower. The evaporator coil pulls heat out of the indoor air, and the blower moves that air through the home. The refrigerant lines connecting the two cabinets, and the thermostat on the wall, round out what a contractor reads when tracking down a fault.
The drawing shows a typical central AC layout, and a licensed contractor determines which parts and conditions apply to your specific system.

What HVAC Repair Looks Like in Greensville County
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.

Severe Weather Events in Greensville County
Hard weather puts real hours on cooling equipment. Compressors, capacitors, and refrigerant lines take stress from power surges, heat loading, and rapid pressure shifts, and that wear shows up as repair calls.
