I heard guys removing the r22 ..putting in the 407c adding 80% POE on top of old Mineral...I was told the Old will not circulate without the Chloro...and the POE will just pass it by?...I think i'll be safe and remove it all and start clean ...like you said.....some more work but measure twice cut once...Thanks

Trying to figure out what is seizing up so many compressors I have done this summer? When I turn in the recaptured freon to reclaim company, almost always it tests out as mixed refrig. Or 407C. So I can't get paid for returned freon😒

What if you drop 407c on top of r22? What would happen to the system when you mix the two??

Not supposed to mix them, they use different oils. People do it all the time and it's not proper. will it work? maybe for a while but it's not RIGHT

My 5 ton unit has operated for 4.5 years with a mixture. It now has 70% R407C & 30% R22 with only MO.

A waste of time and money for old residential systems. Give the customer something for their money, new system.

Same here: I still have an American Standard HP air handler with R22; bought new York AC condenser and charged with R407C. It has been running for 9 years with no problems and no oil change either!
