Default Rough idle when a/c is on

So lately after driving for a few mins, ill stop at a redlight and my rpms will move up and down, and my whole truck shakes. This only happens with the a/c on. When i turn the a/c off it doesnt do it. Anyone know why? Its annoying lol

I'm pretty sure thats fairly normal. Your engine is having to run the AC pump which turns on and off frequently, the engine will tend to shake more when the AC is on.

If it is shaking bad it could be a bad ac bearing

I guess it's normal. Hell you can even hear my ac clutch engage. The loud ass click had me thinking something was wrong for the longest time until found out it was normal for our trucks.
