Load bearing interior wall under truss roof.
Truss roof load bearing walls.
If one of the truss webs doesn t come down on the wall then it s not load bearing.
Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located.
It most likely is a load bearing wall even without the hvac unit taken in consideration.
You will need an engineer involved in this since many contractors will tell you anything to get the job.
The roof trusses are too long to span the whole house so the load bearing wall runs down the center of the house to support the trusses at the perpendicular intersection in the middle.
If there is a truss over the wall the wall is probably not load bearing since the truss bears the load.
Truss roofs are typically designed to use some interior walls as mid span support to save on costs associated with making the truss larger stronger.
If there is a column that supports the truss found in the wall the wall still would not be load bearing because the column is taking the load.
Interior walls might be load bearing or may not be.
I ve never seen a 30 truss that needed intermediate bearing but i can t say that it has never happened.
