If the refrigerant's low, it's LEAKING.

A licensed pro can't legally top off a refrigeration system with a
known leak. If the EPA gets wind of it he'd face fines and would
probably lose his license.

Odds are a leak would require the replacement of one or more major
components. Once you start replacing major components on a unit that
old, you are better off in the long run to simply replace it. You will
be chasing problem after problem if you try to fix it.
