Mixed freon
Hello,
I'm in need of some advice. I have an older R22 system. There was R410 added to top it off. I'm sure the majority of the Freon is R22. Should I flush the system. The leak has been repaired.
Thanks in advance

Yes. And when you recover the freon it will be a mixed batch and the supply house charge more to get rid of this.

This might be a sign that it's time to replace that old 22 system. You're running on borrowed time.

Everything in there needs to be recovered and disposed of properly.
New driers.
A replacement refrigerant need to be chosen but with the age is it worth all that trouble?

No and it doesn't matter!
The old refrigerants are going By By you can only get the newer blends. Are they better, No but thats what the Gouberment allowes!

you can still buy r22. probably could take the exam and buy a 30# tank for what people seem to be gouging for it and have a lifetime supply.
shouldn't really need more than a couple pounds for the next 30 years or so if it is repaired properly.

Gouging
This from a plumber!

If it's fixed and no longer leaking I would recover the charge, replace the filter drier, evacuate and recharge it with R407C or whatever R22 replacement refrigerant is compatible with the oil in the system. I don't think you need to flush the system with anything besides the nitrogen that's used for pressure testing. R22 would be ideal if you happen to have it but you can probably use R407C, R22D or something else.

and once you get certified and has that 30 pound drum of refrigerant where does he get his recovery machine, recovery tank, vacuum pump, on and on! All that cost a lot of money

You can supply it to the tech that is charging it. Or do it yourself after you evacuate it to take a slightly political side step. No one is enforcing the law on small systems.
Plenty of partial tanks on facebook marketplace too.
