This is the best window air conditioner I've ever owned. I purchased the 10,000 BTU model and it does a much better job of cooling the same space that the GE 12,000 BTU model it replaced. Not only that, but it is sooooo quiet. Its quiet in a way that you would not imagine is possible for a window unit. 

Finally, it has the easiest installation ever, and it literally comes with everything you need.
