Well, I understand that it is a 20 ton unit made in 1993, anyway.
I could not follow most of the rest of the posts.
It is working well, and like I said, it is pretty quiet. It is getting old though, so I am wondering in how many years I need to plan to replace it.
I certainly understand the disadvantages of reheat, but it has been hard to figure out how, in this building, to retrofit to something else.
Thanks, everyone, for all the help.
I would say run it until you have cooler barrel breach . Those compressors are plentiful and the chiller design is pretty straight forward.

Thanks, that is a great explanation. I appreciate you following up on my comment with this advice.
I've see many new buildings that use re-heat. Especially churches with the wooden pews and million dollar organs.
