AND i thought the accumulator was to keep liquid from entering the compressor. Pretty sure that the charge level should be the same in heat or cool mode... and please if i am wrong someone plz let me know

But it is a charge compensator that makes up the difference, not the accumulator. The accumulator is mainly for the purpose you stated.
