My AC has been fine. Now blows hot all of a sudden

Did you ever figure out what was wrong? I’ve been having the same issues for the last 3 years or so, I’ve just been dealing with having no AC but I’m about to have a baby and need AC. I tried recharging the AC with one of those kits from autozone but the minute I connected it, it became very apparent that it wasn’t due to a lack of pressure or refrigerant, but just like you the air still blows, so it’s not the fan. I’m wondering if it’s the compressor. Did you ever figure out what was wrong? I appreciate any response- I know it’s been a million years since you posted this question.
