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

Mini split ductless AC unit on wall

Ductless mini-split systems have exploded in popularity. But are they better than traditional central AC? The answer depends on your home, your needs, and your budget.

Head-to-Head Comparison

FeatureMini-SplitCentral AC
Requires ductworkNoYes
Zone controlYes (each unit independent)Limited
Installation cost$3,000-$5,000 per zone$3,500-$7,500 whole home
Energy efficiencyVery high (no duct losses)Good (20-30% duct losses typical)

When Mini-Splits Make Sense

  • Home additions and renovations
  • Older homes without ductwork
  • Garages, workshops, sunrooms
  • Home offices with dedicated temperature control
  • Supplemental cooling for problem rooms
  • Commercial spaces and restaurants

When Central AC Makes Sense

  • Whole-home cooling with existing ductwork
  • New construction (ductwork included in build)
  • Aesthetics matter (no visible indoor units)
  • Even temperature throughout

Can You Have Both?

Absolutely. Many homeowners use central AC for the main house and add a mini-split for a problem area — a bonus room over the garage, a sunroom, or a home addition. This hybrid approach gives you the best of both worlds.
