2-Zone vs Two Single-Zone Mini Splits
The standard two-room fork, priced from our verified dataset: one 2-zone system (below, $2,094-$6,860 of equipment) versus two single-zone systems (the cheapest verified pairs start near $1,300 of equipment). The 2-zone wins on one condenser, one electrical run, and one install visit. Two singles win on redundancy (one failure leaves one working room), simpler DIY (true-DIY exists only as single-zone), and the freedom to size and place each system independently. Neither answer is wrong; the tiebreaker is usually whether the rooms are near each other and whether you ever want a third zone.
