Choice R-421A is the only two-component blend commercially available for R-22 retrofits, which appeals to customers with concerns about refrigerants that contain hydrocarbons such as Butane, Isobutane, and Isopentane. We believe that these properties of Choice R-421A make it an especially good candidate for residential A/C R-22 retrofits, where the simplicity of the retrofit process and the performance are paramount.
