    I noticed my air conditioning clunks like a mofo at start up. It's kinda making me mad. Tonight I'm going to make sure the A/C is off before I turn my truck off. Don't quote me, but I think it only happens if I leave it on. Maybe it doesn't engage as hard once the truck is started and then the A/C is turned on?

    Liquid refrigerant drains back into the pump, and then when the pump engages it momentarily goes over-pressure and makes that noise. Not much you can do about it.

    I have found that if you wait about 30 seconds after starting you engine before engaging the A/C that the clunking sound isn't as bad.

    Old bump, but yes, this is true!
