Mini Split vs
Central AC:
Which Is Better?

One of the most common questions we get from South Florida homeowners is whether to go with a traditional central AC system or a ductless mini split. The honest answer is: it depends on your specific situation. Here's the breakdown to help you make the right call.

Central AC — Best For:

• Whole-home cooling across multiple rooms
• Homes that already have existing ductwork in good condition
• Larger homes over 1,500 square feet
• When you want one thermostat to control the whole house
• New construction where ductwork can be installed during build

Mini Split — Best For:

• Home additions, sunrooms, and converted garages
• Condos or apartments where ductwork isn't possible
• Older homes where installing new ductwork would be too invasive
• Single rooms or zones that need independent temperature control
• Server rooms, home offices, or spaces needing precise temperature
• Maximum energy efficiency — mini splits use inverter technology

Cost Comparison in South Florida

A single-zone mini split installation in South Florida typically runs $1,500–$3,500 depending on the BTU size and installation complexity. A new central AC system installation ranges from $4,000–$12,000 depending on home size, whether new ductwork is needed, and the system brand and SEER rating. For a home addition or garage conversion, a mini split almost always makes more financial sense.

Our Honest Recommendation

For most South Florida homeowners with existing ductwork in a standard single-family home, a central AC system is the right call for whole-home comfort. But if you have a room or zone without existing ductwork — a garage, addition, sunroom, or condo — a mini split is the better, more efficient, and often more affordable solution. We install both, and we'll always recommend the right system for your specific situation — not the most expensive one.
