A single-zone mini split typically costs $3,000 to $6,000 installed by a professional, while multi-zone systems run $8,000 to $19,000 depending on how many indoor heads you add. Installing a pre-charged DIY unit yourself changes the math: the equipment runs about $900 to $2,000, plus $200 to $500 for a licensed electrician to add the dedicated circuit.
Those are national, all-in ranges covering equipment plus labor. Where your quote actually lands depends on the number of zones, the brand tier, how far the refrigerant line set has to travel, the state of your electrical panel, permit fees, and local labor rates. Below we break the cost into two tables — one by system configuration and one by cost factor — so you can build a realistic budget and see exactly where the money goes.
