IECC Zone 1A/2A (hot-humid)

Mini Splits & Heat Pumps in Florida

Florida is the most cooling-dominant state in the continental US. Summer dew points exceed 75°F for four months, hurricane-season humidity lingers from June through October, and even winter afternoons routinely hit 75°F in the southern half of the state. Heating is almost an afterthought except for a handful of nights per year in the panhandle. Saltwater corrosion on coastal condensers is a design-level concern — spec'd outdoor units need coastal/marine-rated coils.

What Works in Florida

Florida buyers should always pick the highest SEER2 rating in the DIY lineup — with 3,000+ CDD per year the efficiency delta pays back fast. Coastal properties need marine-grade coil coatings; Florida's hurricane code also requires specific outdoor unit mounting and hurricane straps in coastal counties. A variable-capacity inverter unit gives much better humidity control than a fixed-speed system during the low-load shoulder months.

Florida Rebates & Incentives

Florida has not fully launched HEEHRA as of early 2026. FPL, Duke Energy Florida, and TECO each run standalone heat pump rebates. Federal 25C credit stacks.

Florida Licensing & Install Rules

Florida requires a Class A or Class B HVACR contractor license from DBPR for installs above the handyman threshold. Homeowner DIY on owner-occupied residence is permitted but requires a mechanical permit and hurricane-code-compliant outdoor mounting in coastal counties.
