Having looked at a unit that was low on charge. It was running but not heating or cooling. And has lost its charge before, I was wondering what the superheat should be ? And would this be the correct way to charge the unit? my only other option is to pull the charge out and weight the 54 ounces it calls for. Its not a paying job, and I really want to help the people out. If I can get it through till next year they would be OK with that. Thanks in advance...
