The formula

Cost = (total BTU / 1,000 x rate) + per-zone install labor + permit

Each additional indoor head adds equipment and labor, so a 3-zone system costs far more than a single-zone unit of the same total capacity.

Frequently asked questions

How much does a mini split cost installed?

Single-zone systems typically run $3,000 to $5,500 installed. Multi-zone systems run $2,000 to $3,500 per additional head.

Can I install a mini split myself?

DIY-ready kits with pre-charged line sets exist, but most jurisdictions still require a mechanical permit, and manufacturer warranties usually require licensed installation.
