necessary a/c repair?

wassup guys. recently i had my evaporator core and expansion valve replaced. before that i had my condensor and condensor fan replaced by honda. im goin to get my a/c serviced on monday. my uncle suggested i also replace my receiver/dryer as well since it may have accumulated moisture. i havent had my a/c work in quite awhile and being in FL it is starting to get a lil too hot for me. so what do you guys think?

do i really need to replace the part or can i go on w/o it?

With all those parts already replaced, they should have already replaced the receiver/dryer. Standard rule is to replace the unit whenever the system is opened up.
