R-454B
Technical overview
R454B refrigerant for compatible A/C and heat pumps
Choose R454B when the equipment label specifically calls for this refrigerant. This HFC/HFO blend is used in purpose-designed air conditioning and heat pump systems. Its designation matters: a system built for R410A or R32 cannot be assumed to accept R454B, even when the application looks similar.
