i think they have some multi-zone units that do run seperate head units to separate rooms that run independently ( some type of variable speed motor in the compressor)You can't run two "separate" rooms off one unit because there are no ducts. I bought a Della brand on Amazon, pre-charged for $800 and I'm in Houston and it keeps my 575 sq ft garage with 11' ceilings nice and cool in summer and ran the heat when it was 22 degrees and it warmed it up nicely. Mine is 110 power on a dedicated 20 amp circuit. I mounted it all, ran all electric, etc. then had an HVAC tech connect, checks lines, verify charge, etc. All in I spent under $1,300 and it's all to code.
