Air conditioning not working.

Hey all, my air conditioning doesn't work. When I turn it, I can hear the motor working but it doesn't blow cold. People I got it from used the freon recharge and said it worked for about two days then stopped. They say they think there's a hole in the hose. Where do I begin trying to figure out how to fix it?

best way to find a leak is to take it somewhere that will refill it and put UV dye in as well e.g. a Halfords Autocentre will do that (not to be confused with a standard Halfords shop). You then search for the leak with a UV lamp.
