How Much Does a Ductless Mini-Split Cost in Phoenix?
Champion Air mini-split installations start at $5,300 for a quality single-zone system, installed. Multi-zone systems scale with the number of indoor heads and line-set runs — flat-rate quoted free in your home.

Where mini-splits earn their keep in the Valley
- EV garages and workshops — conditioned without touching the house ducts
- Arizona rooms, sunrooms, and additions the central system was never sized for
- Casitas and guest houses on their own zone
- Historic homes without ductwork
- The one stubborn room that never cools — a targeted head beats oversizing the whole system
What moves mini-split pricing
- Number of zones (indoor heads) — the biggest driver
- Line-set length and routing (wall vs. attic vs. exterior chase)
- Electrical work — a dedicated circuit is standard; panel capacity matters
- Head style — wall-mount is the value baseline; ceiling cassettes and concealed units add cost
