Solving this problem may be as simple as tightening a screw. Go to your indoor equipment and visually check the outer parts of the system. If you notice that any hardware is loose, or system panels or doors are loose, simply tighten the screws and see if that helps reduce the noise or rattling.
If taking this measure doesn't help, it may be a sign of a failing blower motor or an electrical issue. You'll need to call a professional at this point.
