If you are remodeling your home, strongly suggest using Bonsai (previously Blender BIM) add-on to model and plan.
In addition to getting my layout just right down to the ft, and using current materials (ie, hardwood, cabinet placement). I modeled out HVAC ducts and overall system.
I had planned on doing major renovations (including plumbing, electric, networking) and would have modeled those as well since the walls would be exposed. But ultimately, due to changing political atmosphere, decided to put these on hold.
It does have a learning curve but would have been made collaboration with at architects much easier (exchanging ifc files).
