WARNING: Propane is not a compatible refrigerant. See concerning a warning against using Frost 22A as a replacement for refrigerant in your home or business air conditioning unit. The warning is that Frost 22A is really propane and, while it may work well in your system, could present a distinct safety risk to you and your family if used in your home or business, especially if the system has a leak.
