The topic of new refrigerants was of interest at the National HVACR Educators and Trainers Conference, given the impending phasedown of HFC refrigerants like R-410A.

Manufacturers have created a number of low-GWP solutions that are designed to have similar (or better) efficiencies and capacities than the refrigerants they are intended to replace.

Finding a replacement for R-410A has been challenging, but several alternatives have emerged as top contenders.

The HVACR industry will likely soon be in the midst of another refrigerant change, which is causing a bit of unease amongst some.
