HC's are dangerous.
The HC refrigerents are under review because they are being considered a worse environmental hazard than R12. (that's info from a chain parts house, not my own)
HC's wreak havok on metals (which your A/C system contains many types of).
If a coustomer's system has HC's in it, I can't and won't service it. I have a tester that will tell me it's 134a, R12 or a mix (those cost extra, I can't recycle the r12 in such case). It will also tell me if HCs are present. If they are, I won't touch it. MANY places won't, something to think about if you ever travel in super hot weather and don't carry everything you need to repair any and every part that can go wrong in your car.
