Generally this is the result of either the compressor not running (just the fan is running) or, more commonly, the freon level is low due to a leak in the sealed system, so the compressor runs but is not able to cool. You can usually hear the sound of the compressor starting if there is low freon, while there will be just the sound of the fan but no deeper 'growl' of the compressor when there are any other problems. It is usually not cost effective in small relatively inexpensive window air conditioners to have someone fix either of these problems due to high labor costs, replacement of the entire unit is recommended.
