Sizing a central AC system in Wakulla County means accounting for what the equipment will run against year after year, not just on the hottest afternoon. 242 severe weather events were recorded in Wakulla County, Florida between 2015 and 2024. At that rate, severe weather is part of the normal operating environment, and a contractor who ignores it when selecting equipment capacity and specifying installation quality is setting a system up to underperform before it is a year old. Duct sealing, electrical connections, and the unit's mounting all carry more consequence here than they do somewhere where the air stays calm.
Ductwork in a house this age was laid out for equipment generations removed from what a new central AC system requires. Half the homes in Wakulla County, Florida were built in 1998 or earlier (2020-2024 ACS 5-year). What a contractor has to determine first is whether those existing ducts can move the air a new unit will push through them, and whether the electrical service at the panel will carry the load. If the ducts cannot, the install scope changes before a unit is ever selected.
The Parts of a Central AC System You Are Buying
The outdoor condenser unit sits outside the house, usually on a concrete pad at ground level, and houses the compressor and condenser coil. Inside, the air handler mounts in a closet, attic, or utility space and holds the evaporator coil and blower. These two units are the core of what a contractor installs.
The thermostat goes on an interior wall where it reads the temperature of your living space and signals the system to run or stop. A refrigerant line set runs between the outdoor and indoor units, and a condensate drain line carries moisture away from the air handler to the outside or a drain.
The drawing shows a typical layout, and a licensed contractor determines what fits the specifics of your 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.

Severe Weather Events in Wakulla County
Florida's climate puts real stress on HVAC equipment, and local weather history is part of what shapes how hard a system has to work over its life. For a central AC installation in Wakulla County, that workload is a local fact, not a national average.
