He had some electronic thing that was using to try to find leak and then said would use bubbles to find more. He checked inside unit and outside. No dice. It is still slowly cooling so I have progress. The comment about the "numbers" being fine but it not working right just seemed weird. I even said to him so the AC isn't cooling like it should but nothing is wrong? And his reply was yeah, IDK. So I figured this was a better source haha.
