Bought this to provide cooling to our added on, and not ducted, Arizona room.  (11x20). The portable ac does a good job of cooling this size of room. Runs smoothly and quietly. It’s parked at one end and my wife’s desk Is at the other. Noise not an issue at all. The only negative so far; the instructions downplay the need to drain the unit. It is supposed to return most moisture collected through the unit. When the relative humidity is Arizona low, like 5-15%, this is true.  But during monsoon season with humidity levels up to 60%, still low compared to the south, the unit produces over a gallon of water a day. Should be emphasized better.
