Ours just went up several months ago. I found most of the repair companies won’t do anything with freon. We had a slow freon leak and ended up just getting a new one. One guy who looked at it (not from a company) said the line was laying in the tray where the water evaporates and it corroded, or something like that. Anyways, it was decided the cost would be too much and we just got a new one. Sadly, the ones they make these days are nowhere near as good as the one we had, but that’s a different issue.
