If the furnace itself is in the attic, the humming is likely caused by electrical components in the furnace--most likely, the blower motor, or else a transformer or relay coil. If the furnace is located elsewhere, the humming may be caused by a damper motor or possibly the air movement itself vibrating a damper or some sheet metal.The HVAC Veteran
