Over the years I've occasionally been told by (HVAC) contractors that mechanical humidification is required on forced air systems in Chicago.
Sometimes this has been represented as a Building Code requirement, sometimes as a requirement by the Health Department, but no one has ever been able to provide a cite.
Is this a actual requirement, or a Urban Construction Legend?
