Old HEIL CA3048VKA1 A/C What Type of Refrigerant?

This is the original A/C from when the house was built in 1989.
The condenser coil was replaced around 2007 and the system was recharged, it is
still working but seems a bit weak.

Would it be an R22 system and did they likely recharge it with R22 or something
else? Are they required to tag it in any way if they make a change?

If the system was installed in 1989, the refrigerant is almost certainly R22.

The replacement compressor for that model number shows R-22.

Thanks very much for confirming that.
Were there replacements in 2007 that they might have used or would they have
just used the same R22 at that time?

Edit: I should have said in the OP that they replaced the evaporator coil.

A/C seems weak and probably needs a charge, should I consider having a tech do the
407C conversion including the oil?

On an older unit/system like that.... no. Stay with the R22.
