Can I convert a heat pump or air conditioner from R-22 refrigerant to R-410A, or switch R-410A to R-22?

Theoretically Possible But Not Practical
No, you cannot just evacuate R-22 from a system and replace it with R-410A, or vice-versa. Both the condenser and evaporator units of a system are designed specifically to be compatible with only one refrigerant, and will not function if it is changed. While it is possible to replace multiple components of an older R-22 HVAC system so that it will operate with R-410A, the parts and labor cost makes it a terrible investment compared to upgrading to a new the system—which would also be higher efficiency. Plus, the converted systems do not always perform satisfactorily.
R-22 is an older refrigerant that has been being phased out gradually since 2010. Remaining supplies are limited and becoming more expensive, so going from R-410A backwards to R-22 makes even less sense.
