Very disappointed. This unit is advertised to fit windows 20"-44" wide.The  window panels for venting this unit do NOT fit windows that measure between 33"-39". Using one of the side panels will fit a window up to 33" and using both panels the  minimum length is 39". Haier's solution to this is to use a table saw to cut the panels. Can't comment on the actual cooling unit since we can't install it until we find someone with a saw.
