Ductless Mini-Split Installation Cost
A ductless mini-split heats and cools without ductwork, using one outdoor unit and one or more indoor heads. Installed cost runs $2,000–$14,500, mostly depending on how many rooms (zones) it serves.
What changes the price
- Number of zones: a single-zone system for one room sits at the low end; multi-zone systems serving several rooms cost more.
- Indoor unit type: wall-mounted heads are most common; ceiling cassettes and concealed ducted units cost more to install.
- Line set length: the refrigerant lines between the outdoor and indoor units; longer or harder runs add labor.
- Electrical: most systems need a dedicated circuit; an older panel may need an upgrade.
- Condensate drainage: each indoor head needs a way to drain water.
- Mounting: wall brackets, ground pads or a roof stand.
Good uses for a mini-split
- Additions, garages and converted attics without ducts.
- A room that is always too hot or cold.
- Older homes with radiators and no ductwork.
- Zoning, so unused rooms are not heated or cooled.

Questions to ask
- How many zones do you recommend, and what size is each head?
- Where will the indoor heads and outdoor unit go, and where do lines run?
- Is electrical work included?
- How should the filters be cleaned, and how often?
