I guess this spring I'll removed the drywall roof in the basement and look up there. The basement was finished years ago, I guess. Bought it 2 years ago. A support in this area would be quite, "in the way", but I'll need to evaluate. Again though, I have a furnace duct (hanging) that runs perpendicular to the joists, like the beam would. Maybe that beam is still up there. Spring project here I come.
