A contractor diagnosing a failed central AC unit in Boyle County has to establish what actually wore the system down, and the weather record here does not usually point to itself as the answer. 60 severe weather events were recorded in Boyle County, Kentucky between 2015 and 2024. At that rate, severe weather is an event in this county, not a steady grind on equipment. A compressor that has given out, a capacitor that has failed, a refrigerant circuit that is leaking: a contractor looks first at how long the system has run and how well it was put in, because those two factors account for most of what breaks here.
Ductwork and wiring in a house get adapted over time, but the equipment inside gets replaced wholesale. Half the homes in Boyle County, Kentucky were built in 1978 or earlier (2020-2024 ACS 5-year). That gap between the building and the system now running in it means a contractor opening a central AC unit here is not looking at original parts in an original context. What they find could be a compressor or coil from any of several generations of equipment. Whether the manufacturer still makes what that unit needs is what drives the repair scope, and a part that is no longer produced turns a straightforward job into a decision about the whole system.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along an exterior wall, and it holds the compressor and condenser coil. These are the pieces a contractor looks at early in a repair call. A failed compressor or a fouled coil can shut the whole system down.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower fan. The coil sits above or below the blower depending on the cabinet style. A clogged evaporator coil or a blower that has lost capacity are common reasons a system runs but delivers little cooling. The refrigerant lines that connect the indoor and outdoor units run between the two cabinets, and a contractor checks them for leaks whenever the system is short on refrigerant.
The drawing shows how these pieces relate in a typical layout, and a licensed contractor will determine which components are relevant to the specific system in your home.

What HVAC Repair Looks Like in Boyle 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.
