I bought this model 3 years ago in summer of 2020 as an upgrade from a smaller unit. This unit has great power and delivers nice, cooled air on those hot summer days. I use it for my master bedroom which is smaller than average. This unit cools the entire room quietly and efficiently. No problems whatsoever. I love this unit it is the best one I’ve ever had for this room in the past 13 years at my current residence. I highly recommend.
