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.
Quick answer: car A/C repair in Chennai
Bring the car to our Ambattur workshop and the free 30-point A/C and electrical checkup tells you what is actually wrong before anyone quotes you. Gas filling is ₹1,500 for a single module and ₹2,200 for a double, leak check included. Compressor, condenser and evaporator work is diagnosed first and quoted after, because the price depends on what the inspection finds. You approve the written estimate before any paid work begins.
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.
Electrical diagnosis →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.
