Alright, I broke the cardinal rule and set up a friend of mine with a cheap setup consisting of a 2.5 ton HP that we took out under warranty, and an aspen coil with a TXV, it sits atop his electric furnace in a trailer. The other day he told me it was kicking the breaker, so I checked and it was shorted to ground. My question is, if I shoehorn in a 4 ton compressor I have laying around, how likely is it that I will be changing it again soon? Or is it even feasible? I'm not familiar with mis-matches since we always match our equipment. I'm just looking to get him up and running again before summer as cheap as possible. I appreciate any help.
