Is rheem model Raka-042jaz an R22?

The Rheem model RAKA-042JAZ is a ducted air conditioning unit that typically uses R-410A refrigerant, not R-22. R-22 has been phased out in many regions due to its ozone-depleting properties, and newer models like the RAKA series are designed to use more environmentally friendly refrigerants. Always check the unit's specifications or consult the manufacturer for the most accurate information.
