Car A/C Repair in Chennai — Diagnosed First, Quoted After
Cooling gone weak, noisy or dead? The free 30-point A/C and electrical checkup finds the fault before anyone quotes you a part. Ambattur workshop, Monday to Saturday, 10 AM to 8 PM.
What we repair
GM Car A/C Service is a multibrand workshop in Kallikuppam, Ambattur. A/C is the specialism, and the same bay also handles general service, electrical faults and the parts that a diagnosis turns up.
A/C not cooling
Weak air, cools only while moving, or nothing cold at all. Usually refrigerant charge, airflow or a failing compressor.
A/C not cooling →Refrigerant leaks
Cooling that fades weeks after a refill means the gas is escaping. We find where before we refill again.
Leak detection →Compressor faults
Clutch not engaging, rumble, knock or squeal. Diagnosed before replacement is ever recommended.
Compressor repair →Condenser and cooling coil
Blocked fins, fan not cutting in, or a leaking evaporator behind the dashboard.
Condenser work →Smell and cabin air
Musty air on start-up is usually the evaporator and the cabin filter, not the gas.
Odour treatment →A/C electrical faults
Relays, fuses, blower resistors and wiring. The free checkup covers thirteen electrical points.

What it costs
Two things carry a published price. Everything else is quoted after the car has been looked at, because guessing a compressor price over the phone helps nobody.

How a repair runs
- The free 30-point checkup. Seventeen A/C points and thirteen electrical, about fifteen minutes, with vent temperature and battery voltage written down. Those two numbers are the evidence if the car ever comes back.
- The findings, shown to you. Each point is marked OK, Attention or Urgent. Anything marked is explained, not just listed.
- A written estimate. Parts and labour itemised. Nothing paid starts until you approve it.
- The repair. Vacuum, correct refrigerant type and charge weight for your model, and a re-test afterwards.
- Delivery. Vent temperature re-checked in front of you, with the invoice and the next service date.
Model guides that follow the same order: why a Baleno A/C compressor cuts on and off and where we start when a Kwid or Triber is not cooling.
