Why does my AC blow hot air when it is set to cold?

Answer

Most air conditioners blow cool air at first till the pipes that carry the cool air turns cold, then you get the cold air. If you are getting hot air then perhaps your Freon is in need of re-charging. That would be a good first step in finding your problem. If after re-filling your Freon you still have problems you might want to check for leaks, but this is better done by Air Conditioning garages.
