Change is coming once again to the HVACR industry, as there is a growing movement to transition from R-410A to lower-GWP refrigerants. California, for example, is proposing a GWP limit of 750 for all new stationary air conditioning systems (residential and commercial) in California starting Jan. 1, 2023, and other states are planning to follow suit.

To meet this demand, OEMs started exploring the use of mildly flammable (A2L) refrigerants, which have been identified as a lower-GWP solution for many types of comfort cooling applications. Indeed, R-32 has already been endorsed by the Daikin, Goodman, and Amana brands, and they have announced their intention to replace R-410A with R-32 in their ducted and ductless light residential, light commercial, and applied products.
