A/C Compressor Noise

The compressor on our 2005 Liberty V-6 makes a "clacking" sound. It engages OK, but when it disengages it sounds like the gear does clear all the way. It also seems like the A/C is on whenever any mode (Heat) is selected. Appreciate any help. Need to leave on a short trip and can't risk problems.

Sounds like the AC clutch may need replaced, they're electromagnetic and when they wear out enough they'll make some noise on engagement and disengagement.

Yes, the AC compressor also cycles during some heating modes as well to keep from fogging up the windows due to humidity so no concern there with it cycling.
