Air conditioning?

Advice on AC needed;

I am working on an ESP project (1989 Ford Mustang LX 5.0)
and now that the weather has gotten warm I find the AC is not
working.  I suspect that the coolant has all leaked out.  I know
I will need to update to the new type of coolant.  Can I do this
myself with a kit from a auto parts store, or should I take it to
a professional (like a dealer?)

Of course I could just remove the AC system, but  I have to drive
this car every day.  :)

        Thanks,

                Lindsay
