So, when I bought my car a few months ago the guy said it just needed the AC charged...., ha, really. So, a couple months back my brother charged my AC - and you could hear a very distinct sound of a leaking hose (kind of around the front left side of the car I think) - but the AC blew cold top and bottom while there was still Freon in the system. A few weeks later I noticed that my feet were always getting hot, so I felt down by the bottom vents and lo-and-behold they were blowing heat. All climate control is off. So..., my compressor and blower should be fine because while there was Freon in the system it blew AC just fine, right? If not I got two spares of each from parts cars. But this leaking hose I heard, where could that be located? I didn't think it sounded like the hose coming off the compressor - I was Googling around to figure out where the hose went and potential areas that could leak, but I wasn't using the right keywords or something because I came up empty, thus here I am.

Any suggestions/help would be greatly appreciated, thanks!
