Ductless or central AC — which is right for a Florida home?
Start with the job, not the equipment. If you're cooling a whole house that already has usable ductwork, central AC is usually the most cost-effective path. If you're conditioning a space ducts can't reach — or a home that never had them — a ductless mini-split is typically the better answer.

Side by side
| Factor | Ductless mini-split | Central AC |
|---|---|---|
| Best for | Additions, lanai/garage conversions, casitas, and single hot rooms | Whole-home comfort in a house that already has ductwork |
| Ductwork | None required — ideal where ducts don't reach or don't exist | Uses or needs ducts; leaky ducts waste energy in hot attics |
| Zoning | Room-by-room temperature control built in | One zone by default; zoning needs added dampers/controls |
| Efficiency in Florida | Inverter compressors run efficiently at part-load most of the year | Very efficient for whole-home loads; modern SEER2 systems are strong |
| Appearance | Visible indoor head on the wall or ceiling in each room | Hidden — only vents and a return grille show |
| Up-front cost | Low for one zone; can exceed central AC for whole-home multi-zone | One system covers the whole house, often better value with existing ducts |
When central AC wins
Central air is usually the better choice when you're cooling the whole home and the ductwork is in decent shape.
- Your home already has usable ducts and you want one system for everything.
- You'd rather not see indoor units on the walls of every room.
- You're replacing an aging central system — often the simplest, best-value upgrade. See our repair-vs-replacement guide.
When a ductless mini-split wins
Ductless is the better fit whenever ducts are the problem — too costly to add, too leaky to trust, or simply not there.
- You're adding a room, or converting a lanai, garage, or porch to living space.
- One room — often west-facing or far from the air handler — never cools properly.
- You want independent temperature control room by room.
- Your home has no ductwork, or extending it would mean tearing into walls and ceilings.
You don't have to pick just one
A very common Space Coast setup is central AC for the main house plus a single-zone mini-split for the one space it can't keep up with. That's often cheaper — and more comfortable — than upsizing the central system to brute-force one stubborn room.
What about cost?
There's no single right answer on price — it depends on how many zones you need and whether usable ducts already exist. A one-room mini-split is one of the more affordable comfort upgrades; a whole-home multi-zone system is a bigger investment than many central installs.
About pricing
Costs swing widely with the number of zones, equipment tier, and install complexity, so we won't pretend an online number is real. As estimates for the Space Coast, a single-zone mini-split often runs about $3,500–$6,000 installed, a multi-zone ductless system about $8,000–$18,000+, and a new central AC about $5,000–$12,000+ — confirm exact pricing with Anna's.

How Anna's helps you decide
We won't push a mini-split where central AC is the better value, or vice versa. Our woman-owned team looks at the actual space — square footage, sun exposure, existing ductwork, and how you use the room — and recommends what we'd put in our own home.
