I have a 14 foot span that is load bearing on 1st floor, 2x8 joists. What is needed to support the weight on this cape in connecticut.
While Ecnerwal is probably right, a little expansion is appropriate here.
You'll probably need a steel beam to hold it up. You can take a stab at a laminated beam, but steel is the gold standard because a steel I-beam holds far more than a laminated beam.
If it were my house, I'd make sure I get it right because if you don't the cost of repairs could be far more than a steel beam. Or a structural engineer.
