R454B refrigerant will replace R410A in new HVAC systems in 2025.
- Lowest GWP Value Option for R410A (GWP Decrease 78%)
- Better capacity and power compared to R410A
- Very close features compared to R410A – small conversion work and costs from one system to another
- Very low thermal slip – can be removed after leakage
- Nontoxic and slightly flammable (ISO / ASHRAE 3) A2L)
- Allows a minimum fill value of over 1.7 kg (e.g. ISO 5149 or EN 378)
- POE-compatible
What Does This Mean For Customers?
At the moment, not much. If your air conditioner or heat pump is running efficiently, there’s no immediate action that needs to be taken. You still can use your AC with R410A Puron, in 2023, maybe Puron prices will rise and refills or repairs will rise in price. Also, be aware that the introduction of a new flammable refrigerant will require more professionalism from industry workers. We advise you to always contact licensed companies and not attempt to repair equipment yourself or hire non-professional workers. This can be dangerous for your home. If you need HVAC services, please contact our company, our employees are always trained on the latest security protocols and all industry trends.
In a worldwide effort to address climate change concerns, global leaders have proposed a phase-down of high Global Warming Potential (GWP) refrigerants as a part of the Kigali Amendment to the United Nations’ Montreal Protocol. Although the United States as a whole has not yet ratified this agreement, states involved in the U.S. Climate Alliance* are embracing the reductions. Based on proposed California regulations, it is anticipated that many U.S. states will be limiting the GWP for refrigerants used in HVAC applications to a maximum of 750, possibly as early as 2025.
Our current R-410A refrigerant, while excellent at providing a non-ozone-depleting alternative to R-22, has a GWP of 2088, well above the anticipated future limit. That is why we are in the process of developing new products that will use R-454B refrigerant. The new R-454B is a blend of R-32 and R-1234yf. It has a much lower GWP — 465 — which easily surpasses the proposed 2025 requirement. And, it will continue to meet the anticipated future Kigali phase-down requirements well into the 2030s
R454B refrigerant A2L class flammability classification allows for higher loading rates than other flammable refrigerants. By following guidelines and standards, the use of these refrigerants is safe – despite the flammability classification.
