A low hum in Inside, Hutchinson

Very low frequency rumble I first noticed this last winter, 2018. I thought it was our furnace fan, possibly a bearing. It was a very low rumbling sound. I even called our furnace company and asked them about it. They said it was probably the gas coming through a valve in the furnace. It is now summer, 2019. It is not the furnace! I still suspected the blower fan on the a/c. (same unit used for furnace) I turned the unit completely off and the rumbling was still there. Thus, that was eliminated.
