I bought this nine days ago. Today was the first day to use it. I'm happy with it. I like that it's an energy star. I hope to have it for several years to come. I had a white westinghouse for 23 years & went out the last couple of hot days that we had. I love that it has a remote control.

Does the job well. Cools our upstairs efficiently. Power saver feature not recommended. Cuts off and on to often. [This review was collected as part of a promotion.]

I was little apprehensive at first, because there were not many good reviews for this item. I and my husband installed this air-conditioner. It was not difficult, but be careful! It is heavy! I like this design. It is also working very very well! Now, I’d love to recommend this!

I bought it little bit more than a month ago and so far satisfied. Cooling really well, also I like auto mode so it stops when temperature reached your desired setting. It is not very quiet as I would like but the noise is not worse than the other units I have.

The unit itself is fine. Cools and blows well. It does not come with a sleeve, then the trim it goes with does not fit over the sleeve. Unless you really know what you are getting, I would be careful ordering this sight unseen; hard lessons learned.

Does a good job cooling our entire 900 sq ft apartment. Looks good on the wall and appears to be of decent build quality. I only wish it was running a bit quieter, but I can't ask more for the price.

Love love love. It's an A/C with a remote that cools our 2 bedroom apartment effectively. I though I was going to lose my mind when ours broke. This is definitely a great purchase so far.

We have two 15x15 bedrooms. The air conditioner is in one and when we put a fan in the hall to blow it into the other one in an hour and a half it cools it down beautifully. Works like a charm

We bought this for my mother in assisted living. It has done a good job of cooling her apartment. She love the remote because the unit is mounted high and she can't reach the control. This lets her adjust the temperature at will.
