Is R-410a a blend

Is R-410a  ablend?  Do you have to charge a air conditioner that uses R-410a only as a liquid, or can you also charge as a vapor?

    Yes, R-410A is a blend, but a unique blend.



    Typically, if a system that operates with a refrigerant blend develops a leak, the remaining refrigerant needs to be recovered and new refrigerant added to the system. In the case of R-410A, systems can be "topped off" due to the low temperature glide (0.3 degrees) of the refrigerant.



    As a blend, R-410A is to leave the tank as a liquid.
