Thank you for all the replies and suggestions.
I need to check out what the boards are under that insulation. The stairs unfortunately would not run with the joist. The house was build in 1930 and the best part of the foundation is under the old coal room (it had a footer added in), outside of that the weaker area of the foundation has 3 supports added in for the floor. The foundation has had several "repair" jobs and at 1 point new base boards got put in under half the house. The point of getting an engineer is 100% understood and agreed with, I wanted to learn a little bit before paying people to come in and tell me "this isn't going to work out". Thanks again!
Positively speaking, I have plenty of open breakers in the box and the heating/ac unit can easily take the extra work load!
