Your air compressor is dead or the refrigerant has leaked out. Wait!!! Don't give up yet. This very same situation happened to me. I had air blowing(not cold at all) but the outside A/C compressor was not running. Check your inside unit which is either in a closet or in your attic. There is a water pan underneath it. If it is full of water, it has activated a floating shut-off switch that is wired directly to your outside Compressor. You must remove the water. the best way is with a large wet-dry vac. Then make sure the drainage pipe is properly connected and is not clogged. You can probably fix that by sucking out the drain pipe with your vacuum. Once the water is gone, your floating shut-off switch will re- activate your Air Conditioner. Kind of like the floating ball in your toilet. You may sweat a lot, but you will save yourself a service call and some big bucks. Good Luck!!!

Central Air Conditioners are installed into your house to provide cooling air in every room using a duct system. They are very refreshing on a hot day.
What is the purpose of an air conditioning fan?
the aircondition fan is located in the outside unit of a central AC unit. It sucks outside cool air thru the fins and tubing that contains heat from air collected from inside the house thru the A-coil that's sitting on top of your heating unit. The inside fan in the heating unit blows air thru the cold air moving thru the fins and tubing in your A-coil and blows that air into your house. If you hold your hand above the outside unit while the fan is running you can feel the hot air that's coming from inside, this is how the heat is removed.
