19 yr old unit with freon leak
On Monday ac stopped blowing cold. Was blowing hot air. Tech came out and said there was no freon and there was a leak. It's a 19 yr old Trane/American Standard and holds 6lb 8oz of freon. Mod # is AWX030C100A0 if that helps. He also showed me everything in the handler and basically it's old and dirty and everything needs to be cleaned. I opted to just fill up the freon and not fix anything else. Two days later, blowing hot air again so I imagine the leak is pretty big wherever it is. Technically everything is "working" though I imagine the air quality isn't great considering how dirty everything is and our energy bills are high because it's an old, inefficient system. I live in FL so we have a high demand on the ac. I think I know the answer but thought I'd ask....fix the leak and take our chances with something else breaking down or get a new system? Down here I know 14 seer units are quoting around $4500-5k installed. Thanks for any advice!
