The issue is so complex for several reasons: Vibration can be caused by a single component of the system or the interaction of multiple components.

If your natural gas furnace starts making a loud booming, knocking, or banging noise, turn it off and get out of there. It usually means there's a delay in ignition due to dirty burners. Natural gas heating is the largest in-home contributor to the 7.5 tons of CO2 equivalents produced by US s annually.
Loose parts are to blame for vibrating sounds from a furnace. The circulation fan often is to blame, especially if it is attached directly to the metal cabinet. Loose access panels and framing also can vibrate while the furnace is operating. The solution is to secure the fan or the panels.
Noise #1: Clicking. If your furnace is making a clicking noise, it usually means there's an issue with the ignition system.
