We have NO central AC, so we rely on window units to cool our home.  We had no idea what size to get for our living room.  This cools off our entire downstairs!  Love the economy setting and the sleep setting.  And it keeps our furbaby cool all day!  Did I mention how quite and sleek it is?  We were afraid we wouldnt be able to sit on our front porch, but we can with no interference from the back of the unit!  Buying another one for our upstairs bedroom!
