A wonderful new addition to the back room of my home. This 6000 BTU unit punches above its weight class, effectively cooling a room 100sq ft over its rating! Its quiet, and easy on the power bill. At only 40 lbs roughly, this thing was a breeze to get installed. I did have a helper but it went so easy I am confident that a single person could install this unit. Longetivity is yet to be seen, but everything so far is A+
