Very happy with this energy star AC! It does the job well. Occasionally will build some condensation around the vent when the humidity is high but no other issues. Reasonable noise level, quieter than other units I've used including the one in our bedroom. Plan to purchase another of these to replace that one at some point. We live on the third floor so did not feel comfortable hanging a larger AC out our window. If you have the floor space this is a great option.
