We have no central air conditioner in our house and this air conditioner really puts out the AC.  We have a 80 year old house with no air vents, so my husband and I searched for the perfect ac unit and couldn't find one until we went on Wayfair. Our bedroom is on the upper floor and 600 sq ft, the Elite 12,000 BTU AC does the job . The next best part in the winter it puts out heat, couldn't beat the price and the Energy Star rating makes it even better.
