So I have my AC charged with Freeze 12. Everything is working great. It blows nice and icy cold as well as hold pressure. No leaks. However, I noticed an interesting thing. Once the car has sat overnight, if I turn on the AC for the first time the next day, i get a nasty rattle within what I presume are the hoses underneath the car. I can feel it in the driver's seat. The rattling last for only 1 possibly 2 seconds then immediatly quiets and goes away, from that point, the system operates completely normally. Would this be a sign of overcharging or something else possibly?
