My wife and I bought this air conditioner about a month ago and we couldn’t be happier.  It does a great job of cooling our entire upstairs which is about 1700 sq ft. It looks great and modern and also it has to be one of the quietest window units out there.  My previous air conditioner sounded like a freight train compared to this. We are extremely happy with this purchase.  Not to mention all the neat control features and ability to operate this through our phones.
