Takes about a minute. No obligation.
Before a contractor can tell you what a repair will cost, they have to work out what caused the failure. 112 severe weather events were recorded in Franklin County, Alabama between 2015 and 2024. At that rate, severe weather is a standing condition for equipment in this county, and a compressor or capacitor that has been running against it regularly carries a different kind of wear than one that has not. A contractor here checks whether a failed component gave out from cumulative load or from a separate fault, because the answer changes what gets replaced and what gets left alone.
Ductwork and wiring adapted over the decades can run a serviceable system, but the repair itself turns on something harder to predict before a unit comes apart: whether the parts it needs are still made and in supply. Half the homes in Franklin County, Alabama were built in 1983 or earlier (2020-2024 ACS 5-year). Equipment installed in houses of this vintage has often outlasted the production runs of its own components, so a contractor diagnosing a failed compressor or a worn control board is also checking what the supply chain actually holds for that model. A part that is no longer manufactured turns a routine repair into a scope decision.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad at the side or rear, and it carries the compressor and condenser coil. These are the pieces a contractor reaches first when a system stops cooling, runs constantly, or makes noise it should not make. A failed compressor or a damaged coil will show up here.
Inside the house, the air handler holds the evaporator coil and the blower that pulls air across it. The refrigerant line set runs between the two units, and the thermostat on the wall tells the whole system when to run. A contractor reads the thermostat's behavior and traces the lines before opening either unit.
The drawing shows a typical layout, and a licensed contractor determines what applies to your specific house and equipment.

What happens when a contractor comes out for HVAC repair in Franklin 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.
