Takes about a minute. No obligation.
Before a contractor can tell you what a repair will take, they have to sort out what wore the system down. 87 severe weather events were recorded in Covington County, Alabama between 2015 and 2024. At that rate, severe weather is part of the normal operating life of equipment in this county, not an occasional exception. A condenser that has cycled hard through repeated weather events shows different wear patterns than one that simply aged out, and a contractor working a repair here checks the outdoor unit and its electrical components with that load in mind. The diagnosis drives the parts list.
Ductwork in houses of this vintage has often outlasted two or three rounds of equipment, and whatever is running now was fitted to infrastructure that predates it. Half the homes in Covington County, Alabama were built in 1979 or earlier (2020-2024 ACS 5-year). That gap shapes what a repair contractor actually finds: a unit that looks serviceable from outside may have been patched around failing duct connections, adapted to an undersized return, or fitted with parts pulled from a discontinued line. Once the system is open, the question is whether the components inside still have manufacturers behind them.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house and holds the compressor and condenser coil. These are where most failures show up. A compressor that has seized, a coil that has frosted over, or a refrigerant leak traced back to this cabinet will each stop cooling entirely, so a contractor typically starts here.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower fan. The evaporator coil can ice up or leak; the blower can seize or run without moving enough air. A contractor also checks the expansion valve and the refrigerant lines that run between the two cabinets, since a blocked valve or a damaged line can mimic a compressor failure.
The drawing shows a representative layout, and a licensed contractor determines which components apply to your specific system and home.

What Happens When the Contractor Shows Up
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.
