I heard that R-410a refrigerants do not deplete the ozone layer but do have higher “Global Warming Potentials” than R-22. Is that true?

Yes. R-410a refrigerants do not contain chlorine and does not deplete the stratospheric ozone layer, but the refrigerants do have a higher Global Warming Potential (GWP) than R-22. But when you factor in the energy savings that you get from such an efficent air conditioner, the Total Equivalent Warming Impact (TEWI) is much less than that of R-22 units.
