This purchase has been a life saver. With the recent extreme heat wave in our area I couldn't be more satisfied with my new in the wall air conditioner. Not only was it super easy to install it's even easier to operate. I often use only the fan. It's a little nosier than I expected but not enough to disturb my sleep. As a matter of fact I find it kind of lulls me to sleep. I haven't received my electric bill since installation, which by the way my Grandson did for me. I'm expecting a lower bill than with my previous years old model. All in all, I would say this is one of the best purchases I've made in  a long time. Very, very satisfied. Looks good, too!!!
