I'm taking the Blue Line from O'Hare to Millennium Station -- which stop should I get off at?
Also, how do I get from the L stop to Millennium station? Is it all underground or do I need to go up to street level?

Pretty much what the title says. The sound happens about once a day, usually around 5 or 6 in the morning. Been going on for three months now. Both the furnace and my central AC are working fine. Usually, neither is running when this noise happens. I’ve played the sound for two HVAC pros and neither could diagnose the problem.
Thoughts?
