Availability

The refrigerant blend that you are using must be readily available in future else it will increase the costs instead of savings because you have to pay for evacuation before changing the refrigerant in car .

Never listen to drop in refrigerant

EPA does not use the word "drop in" for any refrigerant on its site.Manufacturers use "drop in" term to tell that you can readily use it with existing R12 Systems.In reality,it is just not possible.The pressure requirement of two refrigerants are never same and it can put your ac system under undue stress (damage compressor or O rings) if you mix two refrigerants.

Equipment Changes

Every refrigerant blend has a different pressure temprature chart (it means that it operates at different pressure).So you will need the changes in your AC before opting for new refrigerant blend.Ask all the details about the changes needed and a detailed calculation of costs.

Cost

You must calculate the cost of refrigerant keeping in mind the rules about the long term investment.Please compare the cost of all the available refrigerant blends.

Leak Testing

Ask the leak testing needed for your refrigerant blend.The new refrigerant blend can require a different leak testing compared to your R134A.

Charging or evacuation equipments

Your refrigerant blend may require completely different evacuation equipment than R134A.Make sure that it is certified.

Environment Friendly

Please enquire about its global warming potential before purchasing it.The lower the GWP,the better it is for humans on the planet.
