In the US, it seems like most in HVAC are overly concerned about the safety issues, while elsewhere, it's widely used. But they don't seem to have any problem with all the lithium batteries in modern electronics. And go figure, R1234yf is flammable and turns into toxic gas when burned...

I read some about hydro carbon refrigerants this summer . Finally bit the bullet and paid a small fortune for a jug of refrigerant for our central A/C . But , I suspect that jug will last as long as the unit will last .
When it gets replaced , it will probably be with a R410a unit . Which is also what my new mini split uses . But , I have a jug of that , too .
God bless
