A2L Training and Information

The New Era of Refrigerant is Here

In 2025, EPA regulations will mandate a change to refrigerants that have a lower global warming potential (GWP). That means a transition from R-410A to R-454B, which has one fourth the GWP of R-410A*. R-454B is in a specific class of refrigerants known as A2L, whereas R-410A is a class A1 refrigerant.

Without going into all the technical details, R-454B offers similar operating temperatures, pressures, and oil compatibility as R-410A – reducing the learning curve associated with the new refrigerant.

However, there are two key precautions that must be taken into account:

• R-454B and R-410A (or any refrigerant for that matter) cannot be mixed or cross-contaminated
• R-454B, as with all A2L refrigerants (including R-32), has a mildly flammable characteristic – meaning:
  • (1) a direct flame source and a high concentration of refrigerant is required to create a flame
  • (2) that if it were to ignite, the flame would likely be unsustainable and
  • (3) the spread rate would be less than half a mile per hour – slower than a typical walking speed.
• These differences do require that additional measures be taken from a servicing perspective to avoid cross contamination and/or make certain no sparks are inadvertently generated.
