A contractor quoting a central AC replacement in Lee County has to establish what actually wore the system down before they can say the install is justified. 81 severe weather events were recorded in Lee County, Georgia between 2015 and 2024. At that rate, severe weather is an occasional event here, not a standing condition, so the load it places on equipment is real but modest. A compressor or air handler that has given out in this county most likely got there through age, a poor original installation, or deferred maintenance. Sizing a new system correctly still depends on the house and the local climate, but the decision to replace starts with what the old system actually went through.
Existing electrical service is where central AC installations in Lee County run into friction. Half the homes in Lee County, Georgia were built in 1998 or earlier (2020-2024 ACS 5-year). Houses of that era were wired for loads that fall short of what current equipment draws, and a contractor sizing a new system has to establish what the panel will carry before anything else is priced. Ductwork from the same period is worth the same scrutiny. Neither question has a fixed answer; what the house actually contains decides it.
What Gets Installed With a New Central AC
The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, which are the mechanical core of the system. Inside, the air handler or furnace-based indoor unit mounts in a closet, attic, or utility room and contains the evaporator coil and the blower that moves air through the house.
The thermostat goes on an interior wall where it reads the home's air temperature and signals the system to run or stop. A condensate drain line runs from the indoor unit to a nearby drain, carrying away the moisture the evaporator coil pulls from the air. Refrigerant line sets connect the indoor and outdoor units, running through the wall or attic space between them.
The drawing shows a typical layout, and a licensed contractor determines exactly how each piece fits the specific setup of your house.

What HVAC Installation 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.
