I had a previous thread talking about our HVAC. Our system is a heat pump which is all matching Trane and dated 1991 (indoor, outdoor and thermostat are all a single system and all dated 1991). The aux and emergency heat is electric.

When we were sold the home, the PO told me "I used to do AC. Once a year, I top up the freon and it works fine, but it's old." A few weeks back before we had several folks in the house and when it had started getting warm, I noticed that the AC wasn't cooling at all. I called a guy who came out and said he put 9# in the system.

You guys said 9# was a ton and a leak should be easy to find because there'd be lots of oil. I turned the AC off the other day and poked around the indoor unit and the outdoor portion and didn't find anything that seemed super obvious, but a lot of the indoor portion of the system is hard to see.

This was the only thing that looked remotely wet or oily. It's missing a cap. I put some water in it and was able to see on occasional tiny bubble pop up from down in the area where the allen wrench would go. I don't know if that was just air working it's way out of dirt or if it's a place that can leak.




The AC seems to be working really well now that it's charged despite the fact that it's 30 years old and the attic space heat management is not good.

We'd like to get the roof replaced and hold off on the HVAC until after the summer. (Actually, I'd like to do both ASAP, but you do work around a budget a bit).
