Welcome! Here are some tips for using this forum.
We have a 10 year old multi-zone ducted Fujitsu minisplit (which covers two zones on the 2nd floor) that just crapped out on us. Acknowledging that the contractor remains the most important part of the equation, I was wondering if you all had a preference on brand? Cooling requirement for the two zones is likely around 15k BTU. Also, not sure if it's possible to just replace the outdoor unit, or if this would require replacing all the indoor components as well (assuming it was replaced with another Fujitsu model).
