SHEET 01 · WHAT THE COURSE INCLUDES

One subject, taught properly

We do not teach four services in three months. We teach HVAC from first principles to master level, and the drafting that goes with it — which is why the syllabus below runs deeper than most full MEP programs.

75+ HRS

Live classes

Weekend sessions over three months, taught on live project files rather than slides.

1000 DAYS

Recordings

Every session recorded and posted the same evening. Rewatch any calculation before an interview.

9 TOOLS

HVAC software

HAP, Duct Sizer, Pipe Sizer, psychrometric tools and AutoCAD — installed and used in class.

1000 DAYS

Class notes

Written notes per session, so you watch the screen instead of copying it.

500+

Interview questions

HVAC-specific, with model answers used by our learners in India and Gulf interviews.

100+ FILES

Design library

ASHRAE and ISHRAE references, vendor catalogues, charts, monographs and finished project files.

5 SHEETS

Excel calculators

Heat load, duct sizing, pump head, ESP and ventilation air change sheets you will reuse at work.

ON COMPLETION

Internship & job help

Portfolio review, CV formatting for HVAC design roles and interview referrals.

ACCREDITED

Certificate

Certificate of completion with a verifiable code, issued under ISO 9001:2015.

SHEET 02 · ADMISSION

Who this course is for

Part 1 starts at what dry bulb temperature means and Part 2 starts at AutoCAD installation. A fresher and a site engineer with eight years of experience can sit in the same batch and both take something home.

  • Final-year students and fresh graduates who want an HVAC design seat, not a site role.
  • Working engineers moving from execution, service or maintenance into design.
  • Draftsmen who can already draw ducts but not size them.
  • Engineers preparing for HVAC consultancy and contracting interviews in the Gulf.
Before you enrol: a laptop with 8 GB RAM and a stable connection is enough. No AutoCAD or HVAC background is assumed — both start from zero.

Mechanical engineers

The natural route into load estimation, duct design and equipment selection.

Electrical engineers

HVAC is where most building services jobs are. The physics is taught from scratch.

Civil engineers

Understand the services that drive slab levels, shafts and false ceiling heights.

Site & QA/QC staff

Read, check and mark up HVAC shop drawings with authority.

SHEET 03 · COURSE STRUCTURE

Two parts, twelve weeks

Design comes first and takes the bulk of the time. Only once you can size a system do you pick up the tool and draw what you designed.

SHEET 07 · CERTIFICATION & CAREER

What you leave with

Certificate of achievement issued by TMD CAD Studio
Sample certificate · issued on completion

The certificate carries a unique verification code, so an employer can confirm it in seconds. It is issued under our ISO 9001:2015 registration, which matters when you apply for roles in the UAE, Saudi Arabia and Qatar.

More useful than the certificate is what sits behind it: two complete drawing sets, a folder of heat load and pump head calculations with your name on them, and the ability to defend both in an interview.

Internship assistance

On completion, we connect you to HVAC consultancies and contracting firms for live project exposure.

Job assistance

CV formatting for HVAC design roles, mock interviews and referrals across India and the Gulf. Attendance in live sessions and assessments is required.
