$/1k BTU is the price divided by thousands of BTU/h of rated cooling capacity, so a 9k head and a 36k multi-zone compare fairly. It ignores efficiency and cold-weather output: check SEER2, HSPF2 and "Heats to" for those, or let thesizing builder weigh them for your rooms.
Mini-splits by size
Multi-zone vs. several single-zone units
A multi-zone kit puts one outdoor unit outside instead of several, which matters on a small lot or a tight wall. Several single-zone units are often cheaper per BTU, more efficient, easier to DIY and have no single point of failure. The sizing builderprices both ways for your rooms.
Head sizes matter. Multi-zone heads should match each room's load: a 12k head in a 120 sq ft bedroom will short-cycle. Most kits ship in fixed head combinations, so check that the heads listed fit your rooms.
Line set lengths. Each head has its own line set back to the outdoor unit. DIY kits include pre-charged lines of a fixed length (often 25 ft); longer runs mean buying extensions or moving to a standard install.
