Loud noise from air conditioner when accelerating

I get a loud grinding / rattling sound from the right side of the engine compartment when accelerating with the A/C on.. Does not all the time and will stop if I turn the air off.

    I do not know much about my AC unit, all I know that it is a bit smaller then normal, one's I've seen. We moved into a house and moving from an apartment we didn't notice the big difference in noise but our neighbor told us that this is the first year it is "this loud" does this seem like it is a serious problem? the reason I am asking is I purchased a service contract but it does not kick in for 30 days.

    fyi... the unit is cooling just fine, just the loud noise

Unit makes a loud rattling noise when operating


Hello, most likely the fan blade is either loose or cracked at the hub causing the blade to hit the fan shroud. You will either have tighten the fan blade or have to get a replacement.

Is the underside rusty? If so, take it to a qualified welding and autobody repair shop to have new metal welded on.

Your symptoms sound like the engine or transmission mounts may have deteriorated.

Loud ticking/knocking/rattling sound when I start/accelerate


hi is it miss-firing as it sounds like a knocking noise can be anything but if you can feel it on the accelerater pedal then the noise sounds like its on the inlet valve side which would transfere the noise up the throttle body where the accelerater is located it could be something as simple as a tappet come loose to a burned valve you need to have a look do a compression test and take the rocker cover off see if theres anything come loose yates210456
