The first brief was filed in the federal case against the EPA rule that would ban the use of non-refillable refrigerant cylinders and require refillable cylinders to be tracked.

Some alternatives to R-410A are mildly flammable (A2L) and thus require updated building codes and standards to ensure their safe use.

Each industry will face some form of transitional period. In the HVAC world, that time is now.

As the HVACR industry transitions away from HFCs such as R-410A to alternative refrigerants that are mildly flammable (A2L), it is not surprising that those who will be handling – or teaching about -- these new products have a lot of questions.

The EPA held a public workshop to explain how it will build off its final 2021 HFC baseline and phasedown rule to establish the allowance allocation methodology for 2024 and beyond.

While change is imminent, gathering the facts about the new refrigerants will help you make the most informed decision.

The HFC phasedown and impending transition to lower-GWP refrigerants were top-of-mind at the recent AHR Expo. With the AIM Act, there is no stopping the transition to A2L refrigerants.

The HFC phasedown started this year with a 10% production cut, which is starting to affect the price of refrigerants such as R-410A.
