A contractor diagnosing a failed central AC unit in Lee County starts with the system itself: how old the equipment is, whether it was installed correctly, and how consistently it has been serviced. 101 severe weather events were recorded in Lee County, Alabama between 2015 and 2024. That puts this area near the middle of the national range, which means severe weather is a real but ordinary part of the background here. It is not the kind of relentless load that wears out a compressor or a capacitor on its own. A contractor who skips past age and maintenance quality to blame the weather is skipping past the likeliest explanation.
Ductwork in a house built before the late nineties was sized and sealed for equipment that no longer exists, and when a central AC system runs harder than it should because airflow is restricted, the compressor and coil collect that strain over time. Half the homes in Lee County, Alabama were built in 1997 or earlier (2020-2024 ACS 5-year). A contractor opening the unit here is looking at components that have been compensating, not just running, and the condition of what is inside tells them whether a targeted repair holds or whether the system has been working against its own infrastructure for long enough that the repair scope has to account for more than the failed part.
The Parts of a Central AC a Contractor Checks First
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and it is where the system sheds heat to the outside air. The compressor lives inside that cabinet and is often where a contractor starts when the system runs but does not cool. The condenser coil and fan work alongside it, and a fault in any of these parts will show up as warm air inside the house.
Inside the house, the air handler or furnace cabinet holds the evaporator coil and the blower fan. The evaporator coil sits in the airstream and is a common source of trouble, particularly when airflow is restricted or refrigerant is low. The refrigerant lines run between the two cabinets, and the condensate drain exits the air handler near the coil, where blockages are a regular finding.
The drawing shows the general layout of a central AC system, and a licensed contractor determines which parts and conditions apply to your specific house.

What HVAC Repair Looks Like in Lee 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.
Licensing and Legal Requirements in Lee County, Alabama
