It's R134a., not R124a. R406 is a blended refrigerant, which has one very
significant implication:

If a leak develops, you must recover all of the refrigerant, and recharge
from scratch, since some of the components of the mix (being larger or
smaller) leak slower or faster than others.

Also, your average mechanic isn't going to carry this stuff, or the tools
and supplies needed to service a system converted to this or any other
alternative refrigerant.
