Understanding Overcharged Systems When too much refrigerant is crammed into your AC system, a few detrimental things happen: Excess Liquid: Overcharged systems usually have an excess of liquid refrigerant flowing into the compressor. High head pressure means there's either an obstruction downhill from the condenser or no heat leaving the condenser. High superheat means the TXV can't feed enough liquid to bring the superheat down, which goes along with no liquid making it to the valve. Assuming indoor & outdoor conditions aren't crazy, dirty condenser coil.Pressure head is a component of hydraulic head, in which it is combined with elevation head.
