This is about twice as big as the small window units. Tag lists it as a 15,100 BTU Cooling. I plugged this in to see if it gets cold, it does. I got it from family that was just wanting a new one. So I wanted it to be of use to someone so thought I might list it. I will consider offers. I can show you it gets cold if you come to see it. Also this should go with out saying but I will anyway this is Used selling it AS IS. I will remove the listing once it is gone so yes it is still available.
