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
| Feature | Mini-Split | Central AC |
|---|---|---|
| Requires ductwork | No | Yes |
| Zone control | Yes (each unit independent) | Limited |
| Installation cost | $3,000-$5,000 per zone | $3,500-$7,500 whole home |
| Energy efficiency | Very high (no duct losses) | Good (20-30% duct losses typical) |
| Aesthetics | Indoor units visible on walls | Hidden in walls/ceilings |
| Whole-home cooling | Expensive for many zones | Yes, standard |
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.
