What to Compare
In Florida's year-round cooling climate, both systems work well — but mini-splits are significantly more energy-efficient, especially in homes with poor duct systems. Central AC is the standard choice for whole-home cooling with one thermostat. Mini-splits excel in additions, converted spaces, or as a replacement for homes where ductwork is problematic. Many Florida homeowners use both.
