Most of them are made by a couple manufacturers and a bunch have had evap failures along with control boards.I have a Lennox brand ducted mini-split system for 2 bedrooms and bathroom that suppliments the original home HVAC. The evaporator failed after 18 months, warranty covered a new unit but I had to pay the labor.
If I was to do it again I'd want to choose a different brand and make sure that it has electric resistance heating coils to provide heat when the ambient is below zero.
