I believe all manufacturers are required to use new type of refrigerants starting January 1, 2025. The refrigerants currently used will no longer be available in new units manufactured after that date.
I would be concerned that as the current type of refrigerant will increase in price as need for it dwindles. In a few years it will likely become very expensive to charge your fairly new system manufactured in 2024 or before.
I am holding off until 2025 to replace my system for this very reason. I will insure that my new unit will operate with the newest refrigerant.
