Sizing a mini-split for a home here starts with what the equipment will run against, not just the square footage inside. 195 severe weather events were recorded in Alachua County, Florida between 2015 and 2024. At that rate, severe weather is a standing condition in this county, and a contractor who ignores it when selecting placement, line-set routing, and mounting hardware is underbuilding for the actual load. Units mounted without accounting for that exposure end up working against the climate rather than with it from the first cooling season. That is the local variable a good install prices in.
The electrical panel, not the unit itself, is where a mini-split installation in Alachua County gets decided. Half the homes in Alachua County, Florida were built in 1988 or earlier (2020-2024 ACS 5-year). Housing of that vintage was wired before modern cooling equipment existed, and what a contractor finds at the panel determines whether the new system connects cleanly or whether the service has to be brought up first. Ductwork is less often the question with mini-splits, since the system bypasses it, but the electrical capacity the house was designed around is a different matter entirely.
The Mini-split Components Involved in an HVAC Installation
The indoor air handler mounts high on an interior wall, usually in the room being conditioned, and delivers treated air directly into that space. The outdoor condenser unit sits outside the home, most often along an exterior wall or on a pad beside the foundation, and houses the compressor and fan that drive the whole system.
A set of refrigerant lines and a condensate drain line run through a small penetration in the wall to connect the two units, and a dedicated electrical line feeds the outdoor unit from the panel. A disconnect box is mounted near the outdoor unit as well, giving the system a local shutoff point.
The drawing shows the general layout of a mini-split system, and a licensed contractor determines what applies to the specific conditions of your home.

Severe Weather Events in Alachua County
Florida's climate puts real pressure on heating and cooling equipment, and Alachua County's weather record shapes how hard a mini-split has to work year after year. A system sized and installed for local conditions holds up better than one that was not.
