Mini-Split Installation Cost Calculator
2026 U.S. ductless mini-split planning ranges scale with zone count and layout (single-zone, multi-zone, cassette). Electrical capacity and line-set length move labor. For whole-home heat-pump or furnace+AC swaps, also use the HVAC replacement calculator. Ductless mini-split heads for room additions, garages, or homes without ductwork. Per-zone pricing scales with outdoor unit capacity and line-set length.

Methodology & estimate disclaimer
2026 U.S. ductless mini-split planning ranges scale with zone count and layout (single-zone, multi-zone, cassette). Electrical capacity and line-set length move labor. For whole-home heat-pump or furnace+AC swaps, also use the HVAC replacement calculator.
Actual costs vary by location, home condition, material availability, permits, and project complexity. Read our methodology, the national cost bands table, editorial policy, and disclaimer. Planning provenance uses internal model notes (not invented third-party citations)—see the bands page for published low/typical/high frames.
