Low, soft rumble - as if a large truck were idling in the distance - it varies, but not rhythmically - I can almost "feel" the vibrations. Most predominantly at night, in the bedroom on the second floor. But, I can hear it other times of the day if extraneous noise is at an ebb. Most troubling. I want an answer. Thanks Please advise once the answer is determined. BTW - my better half cannot hear the hum.
