Change is coming to the HVACR industry as state and federal regulations are being enacted that will lead to a phase down of high-GWP refrigerants such as R-410A.

The research was undertaken to develop training programs for firefighting personnel when responding to fires in occupancies with both new and existing refrigerants.

The refrigerant regulatory landscape is changing in the U.S., leaving many scrambling to figure out which lower-GWP solution will work best.

The refrigeration industry can and should continue to challenge itself to focus on what we know are important factors.

Discussion surrounding A2Ls often tends toward safety protocols or their performance characteristics, but A2Ls first have to get to the job site.

Many years ago when the transition from HCFCs to HFCs was beginning, I talked to a contractor who was pretty disgusted with the whole process.

Mixed and low-quality refrigerants damage HVACR systems and can pose a safety threat to technicians.

This article focuses on the refrigerants that will replace R-410A, the most commonly used refrigerant in air conditioners and heat pumps today.
