Ductless mini-split cost
A single-zone mini-split runs about $3,500–$5,000 installed; whole-home multi-zone systems $10,000–$20,000+ before incentives. Here is the breakdown.
Mini-split cost per zone
Mini-splits are priced by the number of indoor heads (zones). One head for a single room is the cheapest entry point; each added zone increases the price.
| Setup | Installed (before incentives) |
|---|---|
| Single zone (1 head) | $3,500–$5,000 |
| 2–3 zones | $6,000–$12,000 |
| 4–5 zones (whole home) | $10,000–$20,000+ |
Whole-home multi-zone
A whole-home system uses one outdoor condenser feeding multiple heads. Size each room first with our mini-split sizing calculator, then total the BTU to pick the condenser. Labor and refrigerant line runs are the biggest variables.
What affects the price
- Number of zones and total tonnage.
- Line-set length and wall routing difficulty.
- Brand and efficiency tier (cold-climate models cost more).
- Electrical work, if a new circuit is needed.
Frequently asked questions
How much does a ductless mini-split cost?
About $3,500–$5,000 per zone installed; whole-home multi-zone systems run $10,000–$20,000+ before any state or utility rebates.
Is a mini-split cheaper than central air?
For one or two rooms, usually yes. For a whole house with many zones, total cost can be similar to a ducted system.
Do mini-splits qualify for rebates?
Many state and utility programs rebate qualifying ENERGY STAR ductless heat pumps. (The federal 25C credit expired at the end of 2025.)
