- R-454B is a low-GWP, mildly flammable (A2L) refrigerant blend of R-32 and R-1234yf designed to replace R-410A in new residential and light commercial heat pumps.
- With a GWP of 466 (over 75% lower than R-410A) it offers higher efficiency and similar operating pressures to R-410A.
- R-454B requires specialized A2L-rated tools and leak detection for servicing.
- R-454B is not a drop-in replacement for R-410A; it is intended for new equipment designed specifically for this refrigerant.
- Unlike R-410A, R-454B cannot be pumped down into the condenser during service; it must be fully recovered.
- While POE (Polyol Ester oil is used in R-454B systems), always verify the oil type approved by the compressor manufacturer for the specific R-454B equipment being serviced.
