    In order to "miss" a circuit. That circuit would have to be restricted. Which would show on start up. And mean they would need to get a new coil then.

    You don't need to get every drop of min oil out of the system.

    Does anyone know for sure, whether or not the mfg(s) would honor a compressor (or any other refrigerant system component) warranty with the 410A/22 mismatch? Or dealt with that situation?

    Most coils made the last several years have been R410A/R22 coils. So there is no mismatch on many of them.

    Haven't had a compressor go out that is on a coil that was used for R22. So never had to file a warranty claim.
