the ticking is most likely the door that moves/deflect the air. turn the fan on high and SLOWLYYYY change the vent setting from dash to floor, pausing 10-15 seconds each setting, you may hear more clicking.
assuming your ac is charged and not leaking, the door/actuators in the dash that move the air around may be the culprit.
lots of threads on this across the internet. I know this for a fact.
