Takes about a minute. No obligation.
A contractor called out for a central AC repair in Bath County has to settle one question before they can price the job: which components failed because the system ran hard against real weather load, and which failed because they were old or poorly maintained. 133 severe weather events were recorded in Bath County, Kentucky between 2015 and 2024. At that rate, severe weather is a standing feature of operating here, and its effects accumulate on capacitors, contactors, and refrigerant lines over the life of a system. A quote that skips that distinction risks replacing parts that will fail again for the same underlying reason.
Much of what a repair contractor finds once a central AC unit is open here is shaped by how long that unit has actually been running. Half the homes in Bath County, Kentucky were built in 1984 or earlier (2020-2024 ACS 5-year). Systems installed into that stock have had years to accumulate wear on capacitors, contactors, and refrigerant lines, and when a part fails, availability becomes a real variable in how the job resolves. A contractor sizing up a repair has to account not just for what is broken but for whether the replacement part is a stock item or a special order.
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 houses the compressor and condenser coil. These are the parts a contractor looks at first when the system runs but produces no cooling, or makes noise it should not make. The air handler or furnace cabinet lives inside, often in a utility closet, basement, or attic, and holds the evaporator coil and blower fan.
The evaporator coil sits inside that cabinet above the heat source and is where refrigerant absorbs heat from the air moving across it. A clogged or frozen coil is one of the more common reasons a system underperforms. The refrigerant lines run between the two units, and the thermostat on the wall ties the whole system together by telling it when to run.
The drawing shows a typical layout, and a licensed contractor determines which components apply to your specific setup.

What HVAC Repair Looks Like in Bath 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.
