Takes about a minute. No obligation.
A contractor quoting a central AC repair in Graves County has to work out what wore the system down before they can say what fixing it will cost. 164 severe weather events were recorded in Graves County, Kentucky between 2015 and 2024. At that rate, severe weather is a standing condition here, and the components that take the load over years, capacitors, contactors, refrigerant lines under repeated stress, are where a contractor looks first. A repair that skips that step may fix what failed today and miss what is about to.
Half the homes in Graves County, Kentucky were built in 1977 or earlier (2020-2024 ACS 5-year). That means a significant share of central AC systems running in Graves County today were installed into buildings that had already stood for decades, and the equipment in those buildings has turned over more than once since. When a unit fails, what a contractor opens often contains components that fall outside current production lines, and sourcing them decides the repair more than any other factor. A refrigerant line that tests fine on arrival may connect to a compressor whose replacement parts sit on a very short list.
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 holds the compressor and the condenser coil. These are the parts a contractor reaches first when the system stops cooling. A failed compressor or a fouled condenser coil is where most repair calls start.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower fan, typically in a basement, utility closet, or attic. The refrigerant line set runs between the two units, and the thermostat on the wall controls when the system runs. A contractor checks all of these when the outdoor unit checks out fine.
The drawing shows a representative layout, and a licensed contractor determines what applies to your specific house and equipment.

What HVAC Repair Looks Like in Graves 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.
