I am looking at adding a 1.5 ton unit in the attic of my 100 year old house to supply the 2nd story with a/c. I would want to mount the outside unit at ground level. What is the max height you can run the refrigerant lines? I just want to make sure this is possible, because I am looking at a height of about 35' with an additional horz run of 30'.
The unit I am looking at is a 12 seer Rheem/Ruud.
