Key Properties of R-454B
Lower Boiling Point
R-454B boils at about -65.9°F, allowing it to deliver strong cooling performance in both residential and light commercial AC systems.
Balanced Pressure Operation
Runs at pressures close to R-410A, which means it offers reliable performance while working with new equipment designed for A2L refrigerants.
Better Energy Use
Engineered to provide efficiency on par with R-410A, so you get dependable comfort without sacrificing system performance.
Zero Ozone Impact
Has an Ozone Depletion Potential (ODP) of 0, making it safer for the planet compared to older refrigerants.
Much Lower Global Warming Potential
With a GWP of around 466, it reduces climate impact by nearly 80% compared to R-410A, making it a future-ready choice.
Mildly Flammable, Low Toxicity
Classified as A2L by ASHRAE—low toxicity and only mildly flammable—ensuring safe use in modern HVAC systems.
