A contractor quoting a new central AC install in Sarasota County is not pricing equipment for a mild, predictable season. 52 severe weather events were recorded in Sarasota County, Florida between 2015 and 2024. At that rate, severe weather is part of the baseline, and a system sized without accounting for it will be undersized for actual conditions. That means duct layout, refrigerant line quality, and unit capacity all get priced for what this county runs against, not for a catalog average.
Existing ductwork is what a contractor prices around on a central AC installation here, and the age of this county's housing stock is why. Half the homes in Sarasota County, Florida were built in 1988 or earlier (2020-2024 ACS 5-year). Duct systems laid down in houses that old were designed for equipment with different airflow demands, and a new central AC unit has to move through whatever is already in the walls and ceilings. If the runs are undersized, the wrong shape, or leaking at the joints, the unit will not perform to its rated output regardless of what was selected or how cleanly it was installed. Electrical service gets checked too, but ductwork is where the real variation lives.
The Parts of a Central AC System Being Installed
The indoor air handler sits inside the home, most often in a utility closet, attic, or basement, and holds the evaporator coil that pulls heat from the air moving through it. The outdoor condenser unit sits on a concrete pad beside the house and holds the compressor and condenser coil, which release that heat outside.
The thermostat mounts on an interior wall and is the control point for the whole system, signaling when cooling should start and stop. A condensate drain line runs from the air handler to a floor drain or outside, carrying away the moisture the coil pulls from the air.
The drawing shows a typical layout, and a licensed contractor determines what applies to this particular home.

What happens on installation day
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 Sarasota County
Storm activity puts a measurable load on cooling equipment, from extended run times to voltage irregularities that shorten a system's working life. How hard that pressure lands depends on local conditions, which is why the installation decision is a local one.
