I purchased a Mitsubishi online, it is the smallest heat pump they make with and inverter. It both heats and cools and is very efficient. I checked out almost every brand of mini-split before I purchased. Fujitsu, Mitsubishi, Solaris, Sanyo, Goodman, Hitachi, etc. For me it was worth buying what most people consider a top name brand, Mitsubishi. The other thing to consider is noise, the Mitsubishi I purchased is rated at 22dB on its lowest setting. This is dead quiet at a distance of 10 feet and actually quieter than my projector. I paid about 1,700 for the unit, roughed it in myself, and paid an HVAC contractor 800 to finish the connections and test it. I have had it almost one year and it was worth the money. Any questions, let me know.
