Guy from Germany here, when I first saw Americans here talking about FCKW I was wondering that theyre still in usage while we forbid them like 20 years ago. We mostly use R744 for Supermarkets, R717 for real big systems, R290/R513 for small refrigerators and R32(/410A) for climate units. How is the development in the US about this natural/low GWP Refrigerants going? Which refrigerants do u use?
Edit: Techs from other country's, please also tell me how you do it
