Heh, I guess it really is like you say Gary "everything is a trade-off"

Your constantly having to balance 1 scenario against another to not only achieve optimum results, but safeguard from trashing the system should the headload drop.

Ok so, with that said, how come we need to remove some refrigerant from the system once its at full load, if charged at idle?

I would have expected the system to require more refrigerant when under load than when under minimal - no load conditions, could you explain plz?

Thanks :E
