I mean, there are almost 200 million R32 units deployed worldwide. It's North America that took forever to adopt it because of Honeywell. The alternative A2L refrigerants, R452B and R454B, are less efficient and proprietary blends. Honeywell's own R-466A isn't getting much traction either.

Regardless, even if companies are going to eventually move away from R32 - they are already mandated to move away from R-410A so R32 is still a better purchase at this time.
