My A/C is blowing hot air. I have had tit charged with freon and it blew cool air for 1 1/2 day but went out again. I here a hissing noise when the A/c is on now. What should I do. I think that there is a leak because it worked one day and then just started blowing hot air as though the freon leaked out.
