A contractor quoting a central AC repair in Union County is not looking for a weather excuse. 82 severe weather events were recorded in Union County, Kentucky between 2015 and 2024. At that rate, severe weather is an event here, not a standing condition, and a compressor or capacitor that has given out is far more likely to owe that failure to age or a poor original install than to what the sky has thrown at it. A contractor will check refrigerant levels, electrical contacts, and the condition of the coils, because those are where the actual story is.
Ductwork and wiring put in generations ago have already been adapted to carry whatever ran after them, and then adapted again. Half the homes in Union County, Kentucky were built in 1976 or earlier (2020-2024 ACS 5-year). What that history means for a repair job is specific: once a contractor opens the unit, the question is whether the failed component still has a supply chain behind it. Systems running in housing this old have often outlasted their own parts availability, and a repair that looks routine from the outside can turn on whether a replacement part is still made.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it holds the compressor and condenser coil. These are where most repairs start. A failing compressor strains or goes silent; a dirty or damaged condenser coil keeps the system from shedding heat properly.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower fan. The evaporator coil is a common fault point when the system runs but does not cool. The blower moves conditioned air into the ducts, and a worn motor or faulty capacitor shows up as weak airflow or a unit that will not start.
The drawing shows a typical central AC layout, and a licensed contractor determines which components are relevant to your specific house and system.

What HVAC Repair Looks Like in Union 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.
Licensing and Legal Requirements in Union County, Kentucky
Kentucky requires a licence to practise heating, ventilation and air conditioning contracting: a person may not do the work unless they have met the state licensing requirements.
Severe Weather Events in Union County
Extreme weather puts real strain on central AC systems, forcing them to run harder and longer than they were sized to handle. How much of that pressure local equipment absorbs is a Union County question, and it shapes what repair work looks like here.
