HVAC Engineer | 2D AutoCAD Drawing & Hydraulic Calculation for Chilled Water & Duct Systems

I am an HVAC mechanical engineer specialising in 2D AutoCAD drafting and hydraulic calculation for chilled water & duct systems.

My services include:

• 2D HVAC drawing, equipment layout, plant room & duct shop drawings

• Duct resistance calculation and chilled water hydraulic balancing calculation, with calculation summary tables delivered

• Equipment substitution check & calculation, especially for Midea and Tica modular chillers and air handlers

This is purely remote technical back-office support.

I only perform drawing work and calculation verification. I do NOT create Revit/BIM models, and I cannot provide German engineering stamp or take local design liability for Germany projects.

I support TGA / HVAC engineering offices with outsourced drafting and calculation work.
