Not Freon anymore.
Anyhow, the refrigirant will never be consumed. Only leak will loss it. The fix it,first pressurize the line to 100 PSI, then use snoopy etc to detect along the line to see where is bubbling, then replace the aged part that causing the leak, then test again, vacuum the line, and fill up the refrig and compressor oil. It is not a DIY job.
