Refrigerant Transition: R-454B

New Low-GWP Refrigerants

On December 27, 2020, the American Innovation and Manufacturing (AIM) Act authorized the Environmental Protection Agency (EPA) to phase down the production and use of hydrofluorocarbons (HFCs). On October 24, 2023 the EPA published the final ruling of 40 CFR Part 48, requiring HVAC manufacturers to transition to the next level of low-GWP (global warming potential) refrigerants for all new residential and commercial ducted HVAC systems manufactured as of Jan 1, 2025.

Cold Point's Choice for the Future

R-454B has been selected as the refrigerant replacement for R-410A in all Cold Point products including residential, light commercial and commercial ducted HVAC applications. Why?

• R-454B has the lowest GWP with the best outlook for long-term viability. This reduces the likelihood that another refrigerant transition will be necessary with a future regulatory change.

• R-454B temperatures and pressures are much like R-410A, resulting in similar system designs and a reduced learning curve for equipment service technicians.

• R-454B provides up to a 78% reduction in global warming potential (GWP) while still enabling the opportunity for optimized unit efficiency and decreased energy use.

What does this mean for you?

Cold Point Corp is well underway converting, testing, and safety certifying our product catalogue with new 454B refrigerant. We expect to have the majority of our products ready for production by the Jan 1, 2025 deadline. Production lead times are not expected to change, pending component availability.
