Purchased to upgrade from a lower BTU unit as it was having difficulty cooling the apartment. Love the new unit as it is keeps the place sub 0 and really like the ability to control it via the app. The main complaint I have is the instructions & assembly were beyond difficult. I got so frustrated I threw them away & just figured it out. I have set up a number of AC units having owned multiple properties & am a very handy person. It almost seems that the instructions and parts provided don’t even match the unit ....
