How much does a mini split cost installed?
A mini split costs about $2,200 to $7,500 installed for one zone, and $4,500 to $16,000 for two to four zones. PickHVAC says to budget $4,000 to $5,500 for a typical one-zone job.
Zone: one indoor unit and the room it cools. BTU: cooling power; a bigger room needs more. Line set: the copper pipes that join the indoor and outdoor units. 240-volt circuit: a dedicated electrical line from your panel, like a dryer's, that an electrician installs.
DIY kits: buy the unit, hire only an electrician

A true DIY kit (pre-charged lines that click together) needs no HVAC contractor, but it needs its own electrical circuit from an electrician. Other mini-splits need an installer to charge the lines.
Kit plus electrician, 12,000 BTU: about $1,759 to $2,959 ($1,459 kit plus a $300 to $1,500 circuit when the panel has room), against $2,800 to $5,200 for a full install.
| Configuration | Installed cost | Yearly cooling | Models we track |
|---|---|---|---|
| One zone, 9,000 BTU | $2,500–$4,500 | $74 | 970 |
| One zone, 12,000 BTU | $2,800–$5,200 | $98 | 947 |
| One zone, 18,000 BTU | $3,500–$6,800 | $154 | 1,116 |
| One zone, 24,000 BTU | $4,500–$8,500 | $212 | 990 |
Installed price for one indoor unit: the widest range per size from HomeGuide and TLS Air Conditioning, as quoted by FixItCost (TLS's range is the wider one at every size). The lowest one-zone price anywhere is $2,200 (FixItCost). Yearly cooling is our computed cost to cool with the middle certified mini-split in that size, at 1,000 hours of running and 18.8 cents per kWh.
Installed cost by number of zones
| Zones | FixItCost, 12,000 BTU wall units | PickHVAC |
|---|---|---|
| 1 zone | $2,200–$5,800 | $3,000–$7,500 (average near $4,800) |
| 2 zones | $4,500–$9,500 | $6,500–$15,000+ (any multi-zone) |
| 3 zones | $6,500–$12,000 | |
| 4 zones | $8,500–$16,000 |
A second zone adds about $2,000 to $5,000; each further indoor unit about $1,000 to $3,000 (PickHVAC). Sources: FixItCost (checked Oct 20, 2026) and PickHVAC (Oct 7, 2026).

From PickHVAC. The typical column comes from a separate PickHVAC table than the $4,800 one-zone average, so it does not add up to it. A circuit is about $300 to $1,500 when the panel has room; PickHVAC puts it at $2,000 to $5,000+ if the panel must be replaced. The kits above include their own line set (25 ft, 11.5 ft, 16 ft, 25 ft).

What moves the price
- Number of indoor units. The biggest swing: see the zones table above.
- Size. The same room costs more at a bigger size, and an oversized unit turns on and off too often. Work out the size you need.
- Line-set length and the electrical run. Extra line set runs $10 to $30 a foot, and a new circuit about $300 to $1,500 when the panel has room, or $2,000 to $5,000+ if the panel must be replaced (PickHVAC).
- Rebates. State and utility programs cut the net cost, sometimes by thousands. See what applies where you live.

Common questions
How much does a mini split cost installed?
About $2,200 to $7,500 for one zone and $4,500 to $16,000 for two to four zones. PickHVAC says to budget $4,000 to $5,500 for a typical one-zone job.
How much of the price is the unit and how much is labor?
About half each. PickHVAC puts the unit and the labor at about $2,000 each on a typical job; the line set, electrical circuit and permit make up the rest (see the parts table above).
Can I buy the mini split myself and only pay for the install?
Yes. DIY kits sell on Amazon from $1,459 to $2,499.98. Their lines come pre-charged and click together, so you only need an electrician for the circuit. Other mini-splits need an installer to charge the lines.
What does each extra zone cost?
A second zone adds about $2,000 to $5,000; each further indoor unit about $1,000 to $3,000 (PickHVAC).
Why do two quotes for the same mini split differ?
The line-set length, the electrical work, the permit and the number of indoor units move the price most. Ask each installer whether the line set, wall bracket, electrical connection and condensate drain (the pipe that carries off water) are in the number.
How these numbers are built. Every installed price on this page is a range published by the source named beside it, read on November 8, 2026: PickHVAC (Oct 7, 2026), FixItCost (Oct 20, 2026) and the HomeGuide and TLS Air Conditioning ranges it quotes for each size. The one-zone range runs from the lowest low to the highest high of those sources, and the same for two to four zones. Amazon prices were read November 11, 2026. Yearly cooling is computed by us from certified efficiency and EIA energy prices; see methodology.
