I have a 94 Suburban that had a new A/C system installed last summer. I've noticed recently (now that the temps are getting warmer) that when I've had the A/C running and then I stop the motor, I hear kind of gurgling noise coming from the A/C, like fluid is still moving through the system. I've opened the hood, and the sound is definitely coming from the A/C, near the compressor. I can put my hand on one of the hoses (which is very cold) and feel the fluid moving through the hose. This noise only lasts a few seconds. Other than the noise, the AC works great.
Is this anything to be worried about? Any ideas what causes it?
