I am working into a little company since 2015, I design air conditioning installation (ducts and split), radiant floor heating, radiator, etc. I can advise perfectly in this area, make thermal balance, and draw all those systems. Also I am working in construction management for single-family housing. I have experience drawing 2D and 3D, I'm currently using Autodesk Revit only, because it is much more efficient and faster than the rest of the BIM software, but I am flexible to use any other type of software too.
