I am a 75 yr old female and do not know about cars other than to drive. on 2006 Hyundai Sonata

My AC does not blow cool air. I am told that I have coolant in it. someone told me that they would have to go in to look at it which will cost me $115. just to look at it. what could be wrong with the info I have given you?
