Read instructions and see if it says anything about cleaning or filters. A.C units **** air in and there is a filter that probably needs cleaned.Also,while cooling, the vent to the outside should put out warm air. Also, if it is less than a year old, contact the manufacturer and they should help you out. Good luck.
