I just took a course on the Fujitsu mini split units. They make them in heat pumps also. They are incredibly high tech and efficient. 19 SEER and higher. Use a ECM modulating variable speed compressor which is very efficient and a bunch of other cool techniques. Probably a bit pricey to install but will save lots of elec $$ in the long run. Quite reliable as they sell them in Russia where the power is bad.
Sounds like sound advice. lol. I dont plan on installing myself. I was just stating how easy they make it look for installation. Im doing the everything except the electrical portion, this would include the heat/cool unit.Simple? Unfortunately not if you want the unit too last and work PROPERLY. There are minimum pipe lengths and procedures to follow for charging it up etc. Proper wiring techniques etc etc. Just like loading computer software "the devil is in the details". They are VERY efficient units and well built from what I have seen. I am not selling them yet so don't know the cost. They can do some amazing things with that variable speed compressor which no one else can. Better humidity control and longer cycles. I would never recommend those for DIYers or inexperienced techs. Someone who has installed lots of them would be recommended. Those are the Lexus units and in an area with high $$ elec costs will be well worth it.
