A/C stopped blowing cold air

I noticed the vents in the back seat weren't blowing as cold and little by little it stopped being cold and not too soon after that the front vents stopped blowing cold as well. My first thought was to recharge it/check for Freon leaks. After doing so, I didn't find any leaks and after recharging it, it was cold so I thought problem solved but after driving it for about a day, the A/C started blowing warm again. I was told to pull out the compressor relay clutch fuse, as well as taking out the HVAC fuse for 10 seconds but that also didn't.
