I have a medical facility that I was asked to quote ductless splits for. My question is, what is the general concensus on the quality of the units such as the Mitsubishi, Daikin, LG, etc. I haven't had the best experience with Mitsu tech support when I was working for another HVAC contractor prior to going on my own. Has that changed or can anyone speak to their experience with Mitsubishi? I've installed Mitsu's and Daikin's, haven't put in any LG's. These would be heat pumps, and I would need a system with multiple evaps, similar to the city multi. I'm interested in the opinion of installing techs or engineers who can provide any insight as to whether one brand has any advantages over the other. Thanks for any help.
