Why a weekend is not enough
A weekend makes you curious. 27 days makes you a technician.
Most people learn car AC the slow way — years of watching over someone's shoulder, guessing, never trusted with the real job. This course compresses that into 27 structured days: classroom logic, live demos, and rotational hands-on on real vehicles.
The slow, informal way
- ✕ Years of unpaid helper work before anyone trusts you with a system
- ✕ YouTube theory with no live vehicle under your hands
- ✕ The electrical side and brand-by-brand differences never learned properly
- ✕ Cannot confidently quote a customer or stand behind a repair
The 27-day GM way
- ✓ Live demos on real customer cars — faults the way they actually show up
- ✓ Full system: gas, compressor, condenser, evaporator, auto-electrical, EV thermal
- ✓ Rotational hands-on in small groups — repeated tool-in-hand time, not once
- ✓ Finish with a certificate, 10+ manuals and a business & pricing playbook
What you will master
The 27-day curriculum
Four progressive phases across 27 working days. Every topic is taught on live vehicles in the workshop — the exact jobs paying customers bring in — reinforced by classroom theory and daily fault-finding drills.
AC fundamentals & gas
- How a car AC system works — components & refrigerant flow
- R134a & R1234yf: safe handling, recovery, evacuation
- Manifold gauge reading — pressures and what they mean
- Gas filling (single & double module) + leak-check discipline
Faults, leaks & cooling loss
- Not-cooling / weak-cooling / hot-air — structured diagnosis
- Leak detection: UV dye, electronic sniffer, soap test
- Cabin filter, blower & airflow faults; AC smell fixes
- When to refill vs. when to repair — quoting honestly
Compressor, condenser, evaporator + electrical
- Compressor: clutch, relay, diagnosis, replacement
- Condenser & cooling-coil replacement
- Evaporator pull-down, dashboard-level work
- Auto-electrical: battery, alternator, wiring, blower, relays, sensors
All brands + running the work
- Brand-by-brand quirks: Maruti, Hyundai, Toyota, Tata, VW & more
- Commercial & bus AC basics; EV thermal systems

Who trains you
A working specialist — not a lecturer
Manigandan G, founder of GM Car A/C Service, has been working on car air conditioning since 2018 and runs a multi-brand AC workshop in Ambattur. The shortcuts and warning signs he teaches took years to learn the hard way — you learn on the real jobs the workshop does every day. Read our reviews on Google.
The GM 2-Day Fit Check
Attend Day 1 and Day 2 in full. If by the end of Day 2 you feel this is not for you, tell us before Day 3 begins — full refund, no questions asked.
Plus — miss-a-module repeat: miss a session for a genuine reason? Sit that same module free in the next batch. You do not lose what you paid for.
What is guaranteed is the training, manuals, mentorship and your seat to repeat a module — not a job or income. Anyone promising those is selling you a story.
