Has anyone installed ductless multi-zone minisplits into post-frame construction residences? If so, what was your method for routing the copper refrigerant lines? This would be during the building process. Assume a slab home without any attic space. Do you run it inside the wall? Or is it possible to install just above the ceilings in the truss space (but even though the lines are insulated, i'm wondering about inefficiencies due to heat buildup of that space). I'm weary about running it through the wall in the event of a modification down the road.
