Propane is an absolute badass refrigerant in a car AC system... Works way better, pollutes less... People just have issues with the whole explosion thing.

CO2/R744 is the way if you can source the components!

Isn’t R744 equipment much more expensive? The pressures are higher?

[–] [email protected] 1 points 1 year ago

They’re expensive mostly market availability of components is still lacking, but it improves by the day.

Much higher pressures - relief valves up to 1740psi on transcritical systems. It sounds scary, but working on a CO2 system is SO much easier imo.
