I think i have read that superheat should run around 30*.
I check the charge on my new unit last night and the direction for charging by superheat. Hears my question
Why is it that newer units superheat runs lower then then the 30* that I think I have read?
As for my unit the OAT=76*,RA=70*,SP=73psi,st=56*,and last sat.suction temp=42* which gives me a 12* superheat, chart called for 10* superheat.
