Best air conditioner ever bought easy to install air blows so nice and cold. this was purchased for the hottest upstairs room in a 2 level home and can i say it blows into the hallway from a pretty big room! The eco feature saves energy when it reaches the same temperature as room it will cut off i tested this took the air conditioner to 68 in a room that was 75 took 1 hour it clicked of and the room was cool for the whole night thanks GE!!
