Retrofit from R-22 to R-410A is

Explanation:
Switching an R-22 system to R-410A isn’t a simple refrigerant swap. R-410A operates at much higher pressures and uses a different lubricant than R-22. The existing components—compressor, valves, seals, piping, and even the oil—are not designed to handle those higher pressures or to work with POE oil common with R-410A. Because of these incompatibilities, a retrofit from R-22 to R-410A can lead to leaks, compressor or component failure, and unreliable operation. The proper approach is to replace the equipment with units designed specifically for R-410A.
