Apologies for asking what is probably a very simple question but I'm a first year apprentice still trying to get my head around this trade . Anyway, was wondering if a system is severly overcharged, what are the ramifications? Does it mean that the evaporator temp is too high and does it put any of the other componenets under stress? Can I also ask the same question but for a system that is undercharged? Thanks in advance for any advice given
