A wort chiller.... ha ha ha ha ha ha.....
That'll work just fine, Hip. The only tricky part will be connecting the copper to the
kettle, and extending the other end a bit so it will stick out of your chiller bucket,
assuming you're using one (I do). I've found a 3 gallon bucket and a tube of silicone
works well, just drill a hole in the side right at the bottom.
What kind of mash are you using? Found a good kettle?

edit - btw - there's no internally toxic elements to be found in an AC, just freon or like
coolants... a good rinsing should be good enough. Pastes won't work for squat
in a coil like that, but you could run some salt / soda through it if you're overly
worried... I just hook my new coils up to the water hose for a few minutes to ease
my mind, then I assume the fluid that comes through will sterilize the rest
In older AC units, you have to be careful using coils that have joints, as some
were made with lead solder, but yours seems to be a continuous peice, so
no worries there
