Refrigerants are chemical fluids that have made air conditioning and refrigeration possible, but they are hundreds or even thousands of times more powerful at warming the planet than carbon dioxide, the most notorious greenhouse gas.

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

      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.
