  The Workshop That Diagnosed What Others Missed

  The Problem AC not cooling · Multiple workshops visited · No diagnosis found

  My car AC had completely stopped cooling during peak Chennai summer. I visited multiple workshops in the area. Everyone quoted very high amounts without actually identifying what was wrong. Some said compressor. Some said gas leak. No one seemed to actually know. I was frustrated and skeptical when a friend suggested GM Car A/C Service.

  The Solution

  Within 15 minutes of arrival, their technician had done a systematic pressure and temperature check and identified the exact problem: the cooling coil (evaporator) needed replacement. No guesswork — a precise, evidence-based diagnosis.

  "Completed in 8 hours at a fraction of what others had quoted. Feels like a brand new car. I wish I had come here first."

  Honda City Owner ★★★★★ Micro Leak Found

  The Minute Hole That Defeated Every Other Mechanic

  The Problem AC repeatedly failing · Multiple part replacements · Still not fixed

  I had spent a significant amount of money at my previous mechanic. He changed the compressor. He changed the condenser. He changed the expansion valve. Every time, the AC worked for a few weeks then failed again. Two months, three visits, four parts replaced — and still no fix. It seemed like an impossible problem.

  The Solution

  GM Car A/C Service did an advanced leak detection inspection using both UV dye and an electronic refrigerant detector. They found what no one else had: a minute pinhole in the refrigerant hose — invisible to the naked eye, undetectable without proper equipment. One precise hose repair. Problem solved.

  "Writing this after 2 months of perfect, uninterrupted cooling. I cannot believe such a small hole caused all that trouble — and that GM found it where no one else could."

  No Jargon. No Upselling. Just Honest Service.

  The Challenge First car · No knowledge of AC systems · Worried about being overcharged

  I bought my first car and the AC wasn't working properly. As someone with zero knowledge about car systems, I was worried about walking into a workshop and being told I needed expensive repairs I couldn't verify. A friend who had used GM Car A/C Service recommended them highly.

  The Experience

  The technician walked me through every component he was checking and explained what each one does — in plain language, not technical jargon. He showed me the actual state of my AC system. When it came to the repair, he only recommended what was genuinely needed and explained why. The bill matched the estimate exactly.

  "Charged only what was fair. Explained everything clearly. As a first-time car owner, I couldn't have asked for more. This is my workshop now."

  Fleet & Bus Owner ★★★★★ Commercial Fleet

  The Workshop That Handles Commercial Fleets Too

  The Problem Tempo Traveller roof AC not cooling · Most workshops refused the job

  I have a small fleet of Tempo Traveller mini buses used for tourism. When one of them had AC issues, I called several workshops in Ambattur. Most said they don't handle commercial vehicle AC, or they quoted without even looking at the vehicle. Finding someone who actually knows commercial vehicle AC systems was frustrating.

  The Solution

  GM Car A/C Service handled the roof-mounted AC system on our Tempo Traveller with complete confidence. Their technician knew the system, diagnosed the compressor issue within an hour, and had the vehicle back on the road the on a booked slot. I now bring all my fleet vehicles here for annual service.

  "Back on road on a booked slot. The only workshop in Ambattur that genuinely handles commercial vehicle AC. Now my regular service partner for all fleet vehicles."
