Sizing a central AC system for Levy County is a local judgment, but the weather load here is not the driver that shapes every decision a contractor makes on the install. 73 severe weather events were recorded in Levy County, Florida between 2015 and 2024. At that rate, severe weather is an occasional fact of life rather than a standing stress on every component, which means age, installation quality, and how well the original system was sized for the house carry more weight in explaining what a contractor finds. A new install priced around storm exposure is a misread of what this county's record actually demands.
Ductwork laid in for older equipment rarely lines up with what a modern central AC unit needs from it. Trunk sizes, return configurations, and branch runs that made sense for one generation of equipment can starve or overload the next. Half the homes in Levy County, Florida were built in 1993 or earlier (2020-2024 ACS 5-year). A contractor quoting a new system in housing of this vintage checks the existing duct layout before pricing anything else, because what is already in the walls sets the ceiling on what any new unit can actually deliver.
What a Central AC System Looks Like Before the Work Starts
The outdoor condenser unit sits outside the house, usually on a concrete pad beside the foundation, and holds the compressor and condenser coil. Inside, the air handler or furnace lives in a utility closet, attic, or basement and moves conditioned air through the home. Together these two units form the system a contractor works with.
The evaporator coil mounts directly above the air handler and is the point where the indoor and outdoor sides of the system meet. A copper refrigerant line set runs between the two units, and a thermostat on an interior wall ties it all together by telling the system when to run.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to this house.

What the Installation Actually Looks Like
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.
