A contractor diagnosing a failed central AC unit in Barbour County has to decide what actually wore the system down. 58 severe weather events were recorded in Barbour County, Alabama between 2015 and 2024. At that rate, severe weather touches equipment here, but it touches it rarely enough that a compressor failure or a refrigerant leak points more directly to how old the equipment is and how well it has been serviced than to anything the sky has thrown at it. A contractor who skips checking the service record and jumps straight to storm damage as the explanation is working backward from the wrong premise.
Ductwork in a house this old has been attached to more than one system over its life, which means the equipment a contractor opens today is not what the house was built around. Half the homes in Barbour County, Alabama were built in 1983 or earlier (2020-2024 ACS 5-year). A system that has run through several replacements may carry components from a manufacturer line that has since been discontinued, and a repair that looks routine from the outside can stall on a parts search once the unit is open. That is where the age of the stock makes itself felt on a repair job.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad along a side or rear wall, and it carries the compressor and the condenser coil. These are the pieces a contractor reaches first when the system stops cooling, because a failed compressor or a fouled coil are common reasons a central AC quits doing its job.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower fan, most often in a utility closet, basement, or attic. The refrigerant lines connecting the two cabinets and the thermostat on the wall are also part of what a contractor traces when tracking down where the problem started.
The drawing shows a typical layout, and a licensed contractor determines which components and conditions apply to your specific home.

What HVAC Repair Looks Like in Barbour 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.
