What a ductless mini-split actually costs to put in
Tell it about your rooms, not about your equipment. The worksheet works out how much capacity the space needs, how many indoor heads that implies, which size in our own list of common head sizes covers it, and what a job of that shape costs — then shows you where each registered dollar figure came from and what it leaves out.
2-zone wall-mounted system, installed
$6,250
Band $4,500–$8,000: sourced (HomeGuide's published 2-zone row, wall heads); historical cost estimate, archived source dated December 9, 2025. Nothing you told us pushes this job toward the top of the band, so the figure sits at its midpoint.
planning figure built from published data — not a contractor quoteSecond opinion from Forbes Home, an unrelated publisher, for the same zone count: $3,100–$7,800 (historical cost estimate, archived source dated August 8, 2025). Where the two disagree we print both instead of averaging them into a number neither one supports.

Floor area of the rooms the system will serve.
Rooms that close off from each other.
Our own labelled adjustment: the ENERGY STAR chart has no insulation term, and we could not obtain a published residential multiplier we were willing to cite.
Open a panel cover and count the empty slots.
Only one city's fee schedule has been read, so only one city can be priced.
What this number deliberately leaves out
- line set beyond the roughly 15 ft that HomeGuide lists in most installation quotes; we could not obtain a price per foot from a source we were willing to cite, so we publish none
- a main electrical panel or service upgrade; our two sources give figures roughly three times apart, so we price neither
- removing and disposing of whatever is there now
- drywall patching, painting, and exterior siding repair around the wall penetration
- condensate pumps and any drain routing that cannot fall by gravity
- the permit fee, because we have read only one jurisdiction's published schedule
Biggest swing factor here: the number of indoor heads; in both source tables each added zone raises the price band.
Two cost tables, printed side by side instead of averaged
We found no government dataset for what a contractor charges to install a heat pump. Every installed-cost figure on this site therefore comes from a commercial cost aggregator, and the honest response to that is not to hide it but to cite two unrelated ones and show you where they disagree. Below is each publisher’s own table by zone count. Where a row exists in both, the bands overlap comfortably; where only one publishes a row, the other column is blank rather than filled in with a guess.
| Zones | HomeGuide, installed | Forbes Home, installed |
|---|---|---|
| 1 | $2,500–$6,000 | $2,400–$5,500 |
| 2 | $4,500–$8,000 | $3,100–$7,800 |
| 3 | $6,500–$11,000 | $3,800–$10,100 |
| 4 | no row published | $4,500–$12,400 |
| 5 | $10,000–$15,000 | $5,200–$14,700 |
| 6 | no row published | $5,900–$17,000 |
| 8 | $18,000–$20,000+ | no row published |
HomeGuide column: historical cost estimate — archived source dated December 9, 2025 (its 8-zone row is printed open-ended, with a plus sign). Forbes Home column: historical cost estimate — archived source dated August 8, 2025. Both live pages refused an automated check on 5 October 2026.
Notice the gaps. HomeGuide skips four, six and seven zones; Forbes stops at six. When you pick a zone count nobody published, the worksheet interpolates between the two rows either side and labels the result derived rather than sourced[3]. That distinction matters more than it looks: a derived band inherits all the uncertainty of the rows it sits between, plus the assumption that price moves smoothly across them, which is not obviously true at the point where a contractor has to add a second outdoor unit.
What the indoor unit style does to the price
The box outside is only half the purchase. Every room you condition needs an indoor head, and the four styles are not priced alike. HomeGuide’s style table is headed “single-zone system”: a wall-mounted system starts at $2,500[7], the lowest-priced style in both publishers’ tables, and a concealed ducted system reaches $7,500[8]. HomeGuide describes concealed units as installed in ceilings or attics, hidden from view, and using short ducts (historical cost estimate, archived source dated December 9, 2025).
| Indoor unit style | Single-zone system, installed | Premium over a wall head (derived) | Where HomeGuide says it suits |
|---|---|---|---|
| Wall-mounted | $2,500–$5,000 | baseline | Installed high on the wall; the publisher calls it the most popular choice. |
| Floor-mounted | $3,000–$5,000 | $500 / $0 | Installed low on the wall; rooms with limited upper wall space, large windows or sloped ceilings. |
| Ceiling cassette | $3,500–$6,000 | $1,000 / $1,000 | Mounted inside the ceiling; larger or open rooms. |
| Concealed ducted | $4,000–$7,500 | $1,500 / $2,500 | Installed in ceilings or attics and hidden from view, using short ducts. |
HomeGuide column and notes: historical cost estimate — archived source dated December 9, 2025. The premium column is subtraction inside that one style table, so both numbers being subtracted were gathered the same way; it is a derived figure, labelled as one on the methodology page. The worksheet adds that premium once per indoor head on a multi-zone job, which is our own assumption: neither source publishes a per-head style premium. Mixing a low end from one publisher with a high end from another would produce a wider, more impressive-looking band that means nothing.

Questions people actually ask about this
How much does a mini-split cost to install?
$2,500–$6,000 for a single zone and $6,500–$11,000 for three, according to HomeGuide's zone table (historical cost estimate, archived copy dated December 9, 2025). An unrelated publisher, Forbes Home, puts a single zone at $2,400–$5,500 (archived copy dated August 8, 2025). The two bands overlap, which is some reassurance about cost-guide data, though neither describes your local market.
Why does this ask about my breaker panel?
Because a new circuit for the outdoor unit is a separate cost if the panel has no spare 240-volt slot. HomeGuide's circuit guide lists HVAC systems among the appliances that need a dedicated 20- or 30-amp circuit; confirm with your installer and the unit's installation manual. When you say there is no spare slot, the worksheet adds a separate line at $650, HomeGuide's stated typical spend on a new circuit (archived copy dated November 24, 2025), rather than folding it into the system price.
Does the estimate cover a long refrigerant run?
No, and that is deliberate. HomeGuide's list of what most installation quotes include names a standard line set of about 15 feet, with higher costs for longer runs. We could not obtain a price per foot from a source we were willing to cite, so this site prints no per-foot figure and instead moves your estimate toward the top of the sourced band.
Is a ceiling cassette really worth the extra money?
In both source tables a single-zone ceiling-cassette system costs more than a single-zone wall-mounted one. HomeGuide describes cassettes as mounted inside the ceiling and suited to larger or open rooms; whether that is worth the difference in your room is a question to put to the installer.
