2-zone mini-split: the short answer
As configured, budget roughly $4,800 – $8,500 for a
2-zone mini-split, rising toward $7,300 – $16,000
once new ductwork and electrical work are included. Each added zone means another indoor head, another line set, and more labor, so a 2-zone system costs more than a single-zone one. Ductless means no duct cost, but the extra zone and the larger condenser raise the total. The biggest swing is
still your own site, so itemize your estimate above.

These figures are indicative ranges, not quotes, and not HVAC, electrical,
or tax advice. Get several written, itemized estimates from licensed HVAC contractors, and
confirm any permit or inspection requirement locally. A different equipment tier, ductwork,
or electrical work can move the total well beyond these ranges. Any 25C tax credit is shown
separately — verify eligibility at energy.gov / IRS.
