I initially bought a different model but when I brought it home I realized that it require a 220 v receptacle. The 15k btu model topped out in the area I needed to keep cool, 850 sq ft. It kept the room at a steady 70 degrees but would not have gone lower due to the size and openness of our home. Very satisfied with it's ability to dehumidify and cool the area for what we were asking. [This review was collected as part of a promotion.]
