Takes about a minute. No obligation.
A contractor called out for a central AC repair in Boyd County has to decide what actually wore the system down, and the area's weather record is not the answer that fits most failures here. 68 severe weather events were recorded in Boyd County, Kentucky between 2015 and 2024. At that rate, severe weather is an occasional event rather than a standing condition, which means the compressor, capacitor, or contactor that gave out was most likely carrying ordinary wear rather than extraordinary load. Age and the quality of the original installation explain the bulk of what contractors find opened up on a system here.
Ductwork in a house built for a different era of cooling gets adapted, not redesigned, and what ends up inside the unit after years of that is rarely what the original installation specified. Half the homes in Boyd County, Kentucky were built in 1972 or earlier (2020-2024 ACS 5-year). A contractor opening a central AC system in this county is working out which generation of components is actually in there, because a system that has been patched and partially replaced over the decades may take parts from a line that has since been discontinued or revised. That sourcing question is what decides whether a repair closes in one visit or stretches while a distributor locates what the unit actually requires.
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 does not cool. The condenser coil wraps around it, and a bent or dirty coil will show up quickly during inspection.
Inside the house, the air handler or furnace cabinet holds the evaporator coil, which sits in the airstream above the blower. That blower pulls air across the coil and pushes it through the house. The refrigerant line set runs between the two units, and the contractor checks it along with the expansion valve and the electrical controls that tell each component when to run.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which components apply to your specific house and situation.

What HVAC Repair Looks Like in Boyd 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.
