Mini-split installation costs $2,000 to $5,000 for a typical single-zone system, with a national average around $3,000.1 HomeGuide puts installed single-zone systems at $2,500 to $6,000, and Fixr’s national average runs higher at $6,357.23 Prices below are national averages* for 2026.

*National averages, not local quotes. Your price depends on zones, BTU capacity, mounting style, and whether you need electrical work.

Why the averages disagree: Angi’s $3,000 reflects a basic 12,000 BTU single-zone install; Fixr’s $6,357 blends in multi-zone systems, our reading of both pages.13 Scope also differs in the zone tables below: Fixr’s per-zone figures are unit-only pricing, while HomeGuide’s include installation, our reading.23

DIY vs pro

Pre-charged DIY mini-split kits with quick-connect line sets are the one realistic DIY path. Home Depot’s mini-split section lists current kit prices (plain link, not affiliate). Anything requiring refrigerant charging or hardwiring belongs with a licensed HVAC pro.
