It may have been an overpressure relief, blown by adding refrig to a system
that had air in it. It's a one-time function and has to be replaced.
I am on the side of those who want to do their own... but every summer I
see posts by people who dont seem to have a clue. And havent bothered to
do the simplest research on problems before they just dump the freon in.
Yeh, I'm a Krusty old Geezer, putting up with my 'smartass' is the price
you pay..DEAL with it!

Don't know the exact fittings on your car, but they all have some
sort of a seal - either an annealed copper or nylon gasket or a rubber
O-ring between the hose fitting and the compressor body. (And it's a
special exotic synthetic rubber matched to the refrigerant and oil
inside the system, not the hardware store type.) Tightening the
fitting could work - or it could rip the gasket and make it leak
The compressor may well be shot - but that has nothing at all to do
with your immediate problem, which is an external leak. ;-P From
your description that it worked for a little while, and you made no
mention of any loud and expensive sounding rattling or banging noises
when it was running, it's probably safe to rule it out. ;-)
Take it in and get the AC fixed properly - it's simple work, and
they shouldn't hit you too hard. About two to three hours of labor.
If the system was leaking and empty for a long time, they need to
recover the refrigerant you put in, fix the leaks, change the
filter-drier cartridge ($50-ish) because the desiccant inside will get
full of moisture from the leak "breathing" in damp outside air for a
few years, check the oil level inside the compressor to make sure none
leaked out, and draw a hard vacuum on the system for a few hours to
get out all the air and moisture that was inside.
Then refill with refrigerant and test it.
If you don't get all the air and moisture out of the refrigerant
system, you'll have constant problems with the expansion valve icing
up - it'll work for 5 minutes, some free water droplets will freeze in
the orifice feeding the inside evaporator (cold) coil, and the system
will quit. Repeatedly, and like clockwork.
