Propane is an excellent refrigerant. I'm surprised that they would promote that. And you don't need an HVAC license to buy it. Many homes already have propane to run their stoves, water heaters, and furnaces. What's so dangerous about using it as a refrigerant? The smoking HVAC guy that connects up to the system deserves the Darwin award.
It is an excellent Refrigerant for small appliances. Those systems hold a few ounces of refrigerant. The average household heating and air system can hold sometimes 10, sometimes 17 pounds of refrigerant. Mainly my concern is leaking evaporator coils sitting on top of furnaces that have open air combustion chambers. it will not be code to install them that way, but you know some shade tree mechanic will.
