substitute refridgerant

[peterphipp]

I have to repair recharge a domestic GE TBX25 . It needs a new condenser and maybe dryer. The compresser is OK. The unit uses CFC 11 and 12. Can I recharge it with a modern gas ? What would I need to change /? Would it work well?

R49 0r 413 would be the drop ins,problem is if you don't use it much buying a 12kg bottle or so would be expensive.
