Central AC vs. Mini-Split: Which Is Right for Your Home?

How each system works

Central AC uses one air handler and a duct system to cool the whole house from a single thermostat. A ductless mini-split puts a small indoor head in each room or zone, connected to one outdoor unit — no ducts needed.

Central AC is usually better when…

• Your home already has ducts in good condition
• You want one thermostat and even temperatures throughout
• You prefer equipment that is completely out of sight

A mini-split is usually better when…

• You are cooling a garage, addition, sunroom or converted space with no ducts
• Different rooms need different temperatures (zoning)
• Your home is older and adding ductwork would be invasive or expensive
• You want very high efficiency — no duct losses, which can waste 20–30% of cooled air

Cost and efficiency

A single-zone mini-split for one room is usually cheaper than extending ductwork. For a whole house, central AC is typically more cost-effective if ducts already exist. Mini-splits shine on efficiency because there are no leaky ducts — a real factor in Florida, where ducts often run through hot attics.
