Have tried to use this unit to cool one small bedroom and after several attempts it will not blow cold air. When using in fan mode it blows air that is the same temperature as when it is being used in the cooling mode. The temperature in the room actually went up 2 degrees after using the unit for an hour in a bedroom with the door closed. I was hoping to use this during the unbearable summer months, but can’t even get it to blow cloud air with temperatures in the 70’s outside.
