Yes it will be cold but it will never be as cold as r12 in an R12 system.

The only reason a system would need a change over to R134A is if something
failed (ie: a leak). Anytime an A/C system is exposed to outside air for
anything more than 30mins or so you MUST replace the Receiver Dryer. Also
there has to be other parts replaced to fix the concern otherwise it was
filled illegally.
