Rheem mini-split highlights:
Mini-split price depends mostly on how many zones you need. Here is roughly what one costs to install, using current national averages.
| System | Typical installed cost (U.S. average) |
|---|---|
| Single-zone mini-split (installed) | $2,500 - $6,000 |
| Multi-zone system (installed) | $6,500 - $15,000+ |
| Each added indoor head | $400 - $1,800 |
Per Angi and HomeAdvisor (2026): mini-split installs average about $3,000 and range $2,000 to $14,500. Single-zone systems run $2,500 to $6,000; multi-zone $6,500 to $15,000+. NYS Clean Heat and utility rebates can offset a large share. Brand, efficiency, and number of zones drive the price.
