This sound may originate from something as minor as loose outside panels that need to be screwed down.

This is probably a problem with the motor bearings. If they\u2019ve become worn down, they will make this noise and will need replacement. Be sure to get this done ASAP to avoid full motor replacement.<\/p>\n
If you hear a rumbling sound deep inside your furnace, it could be the sign of a dirty burner. Ensure that you schedule regular maintenance in order to avoid this.<\/p>\n
