Certified HVAC Draftsman Training Program
Introduction
The HVAC Draftsman Training Program is designed to prepare individuals for a technical drafting role in the heating, ventilation, and air conditioning (HVAC) industry. This course focuses on creating 2D and 3D mechanical drawings, layout preparation, duct routing, and equipment detailing using industry tools like AutoCAD and Revit MEP. Participants will learn to interpret HVAC design specifications and convert them into construction-ready drawings and shop drawings as per industry standards and project requirements.
Modules and Content
Module 1: Introduction to HVAC Drafting
- Role and responsibilities of an HVAC draftsman
- Overview of HVAC systems (heating, cooling, ventilation)
- Understanding project drawings and design intent
Module 2: HVAC Symbols and Standards
- HVAC drafting standards (ASHRAE, SMACNA)
- Common symbols, abbreviations, and legends
- Working with architectural and structural backgrounds
Module 3: Ducting Layout and Detailing
- Types of ducts and materials used
- Duct routing, sizing indications, and elevation levels
- Preparation of single-line and double-line duct drawings
Module 4: HVAC Equipment Drafting
- Layout of AHUs, FCUs, chillers, and diffusers
- Equipment scheduling and annotations
- Space allocation and access requirements
Module 5: AutoCAD for HVAC Drafting
- Layer management and scaling techniques
- Drafting best practices for clean and readable drawings
- Title block, viewport setup, and plotting
Module 6: Coordination Drawings
- Coordination with electrical and plumbing systems
- Reflected ceiling plan (RCP) with HVAC components
- Clash detection concepts and avoidance
Module 7: Revit MEP (Introductory – Optional)
- Basics of 3D HVAC modeling
- Parametric components and system creation
- Creating sections and views
Module 8: Shop Drawings and As-Built Drawings
- Understanding contractor requirements
- Modifying design drawings for fabrication
- Final documentation and submission standards
Module 9: Practical Projects and Case Studies
- Drawing of HVAC systems for a sample building
- Annotating duct levels, diffuser placements, and grille sizing
- Printing final drawing sets for submission
Scope & Advantages
HVAC Draftsmen play a crucial role in turning engineering concepts into buildable systems. With a strong demand across construction, facility management, and MEP design firms, trained draftsmen are valued for their precision and technical ability to communicate mechanical designs
effectively. This course enables professionals to work confidently on architectural coordination, layout preparation, and construction documentation, making them job-ready for roles in consultancy firms, HVAC contractors, and BIM modeling teams.
