HFC's do not contain the alleged ozone depleting chlorine that HCFC's contain. R-22 was "banned" due to the chlorine. HFC is simply Hydrogen, Fluorine and Carbon. We use R-410a in building heating and cooling. R-134a in vehicles.
The Left is Luddite and insane....a horrific combination.
Truth is R-22 did not pose a threat to ozone depletion.
No matter the solution the insane left is never satisfied.
I totally agree. Here’s and excerpt you may also agree with.
Potential options include “natural” refrigerants such as carbon dioxide (CO2), hydrocarbons (HC), and ammonia (NH3) as well as HFOs and HFO/HFC blends. All involve significant trade-offs among GWP, energy efficiency, safety, and cost. Environmental policy must consider the indirect effects of increased CO2 emissions for less efficient refrigerants, not just the direct global warming (GWP) of the refrigerant. We must insist on using metrics such as Total Equivalent Warming Impact (TEWI) that balance refrigerant direct GWP, charge level, leakage emissions, and efficiency of the refrigerant in actual systems. This allows the best possible comparison of refrigerants for each application. In the right policy environment, we can achieve reduced environmental impact and increase efficiency. This will probably require increased differentiation of application-specific refrigerant choices that are associated with somewhat higher first costs but very attractive life cycle costs with acceptable safety and environmental impacts.

And R-22 was found NOT to harm the Ozone. The government came back to Dupont and asked them to start making R-22 again but Dupont said their equipment was already modified to make the new version.
