A contractor quoting a central AC repair in Martin County does not start by blaming the climate. 53 severe weather events were recorded in Martin County, Kentucky between 2015 and 2024. At that rate, severe weather is an event, not a condition, and most systems here have not been ground down by repeated storm load. When a compressor quits or a coil fails, the contractor is more likely tracing years of deferred maintenance or an original installation that was never quite right than working out what the weather did to it. That distinction changes what gets replaced and what gets written on the invoice.
Older ductwork in this county's housing stock carries the history of every system it has run since it was first put in. Connections loosen, lining degrades, and what looked like a unit problem at the thermostat traces back to air loss that a refrigerant charge or a new capacitor will not fix. Half the homes in Martin County, Kentucky were built in 1984 or earlier (2020-2024 ACS 5-year). A contractor opening a system here checks the ductwork as part of the diagnosis, because a sealed and balanced distribution side is what lets a repaired unit actually perform to spec.
The Parts of a Central AC a Contractor Checks During Repair
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and it houses the compressor and condenser coil. These are the parts a contractor reaches first when a system stops cooling, runs constantly, or makes a noise it should not. A failed compressor or a fouled condenser coil accounts for a large share of calls.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower, typically in a basement, closet, or utility room. The refrigerant line set runs between the two cabinets, and the thermostat on the wall controls the whole system. A contractor checks all of these because a problem in one place often shows up as a symptom somewhere else.
The drawing shows a typical layout, and a licensed contractor determines exactly which components apply in your house.

What HVAC Repair Looks Like in Martin 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.
