I have a roughly 40 year old AC unit that is finally failing. I have a Ruud model UAMB-048JAZ that was given to me several years back sitting in my garage that I'd like to get some more information about before I have it installed (or decide to buy a new one instead). I have been searching for information and/or the manual for this unit, but have been unable to find anything. Can anyone give me the specs?
Based on the "48" in the model number, I believe that it is 4-ton. My current unit is a 3-ton, but it is unable to keep up on hot days, so I'm thinking a 4-ton would be okay. Thoughts?
