Takes about a minute. No obligation.
A contractor quoting a central AC repair in Clark County has to decide whether the system failed because of what the climate asked of it or because of how long it has been running without attention. 67 severe weather events were recorded in Clark County, Kentucky between 2015 and 2024. At that rate, severe weather is a recurring factor but not a constant one, which means a failed capacitor or a worn compressor is more likely a maintenance story than a storm story. The contractor will look at the age of the unit, the condition of the coil, and the service history before drawing any conclusion about cause.
Ductwork in a house this old has usually been patched, rerouted, or partially replaced at least once before a repair contractor ever opens the system. Half the homes in Clark County, Kentucky were built in 1979 or earlier (2020-2024 ACS 5-year). When a technician pulls a failed component from a unit running in stock like this, the question is whether that part is still in production, or whether a substitute exists that fits the existing configuration without requiring a second round of work. A hard-to-source part on a system already drawing through modified ductwork can turn a straightforward repair into a longer job than the initial call suggested.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and it is where heat gets shed to the outside air. The compressor lives inside that cabinet and is often the first place a contractor looks when the system runs but fails to cool. The condenser coil and the fan that pulls air across it are examined alongside it.
Inside the house, the air handler or furnace blower pushes cooled air through the home. Attached to it is the evaporator coil, which sits in the plenum just above the air handler and is a common source of trouble when airflow drops or ice appears on the system. The refrigerant lines connect both units and carry the working fluid between them.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components and conditions apply to your specific house.

What HVAC Repair Looks Like in Clark 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 Clark 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 Clark County
Extreme weather puts direct stress on cooling equipment, from hard-run compressors during heat surges to pressure swings that follow fast-moving storms. How often that happens here shapes how hard local AC systems work and how soon repair needs show up.
