Ambattur Workshop: Services & Typical Duration
Durations are general guidance, confirmed for your vehicle at booking or after inspection.
| Service | What it covers | Typical duration |
|---|---|---|
| AC Gas Filling | Refrigerant top-up (single or double module) with a full leak check | Around 30–60 minutes, confirmed at booking |
| AC Leak Detection | UV dye and electronic leak testing across the AC circuit | Around 30–45 minutes |
| Compressor Diagnosis & Repair | Compressor testing with a repair or replacement recommendation | Confirmed after inspection; varies by fault |
| Auto Electrical Diagnosis | Battery, alternator, wiring and fuse/relay fault-finding | Around 30–60 minutes for initial diagnosis |
| Cabin Filter Replacement | Cabin and condenser filter inspection and replacement | Around 20–30 minutes |
| Car General Service | Oil, filters, brake, suspension and coolant checks | Varies by service package and vehicle condition |
AC gas filling depends on the module count, refrigerant type and system condition; other Ambattur workshop estimates depend on the vehicle model, the oil grade and quantity used, the brand and availability of parts, labour complexity for that model, and any existing damage found once the vehicle is inspected. That's why compressor, electrical and general-service work are quoted after inspection rather than published as a fixed price.

On a booked slot View All ServicesWhat Happens to Your Car at the Ambattur Workshop
Every car gets a 30-point sheet at intake. Each point is marked OK, Attention or Urgent. No point is left blank, because a blank is not a pass.
Measured values, not ticksPoints that carry a reading get the number written down: vent temperature in °C, low and high side pressure in bar, battery voltage. A tick without the figure is worthless if you come back.
Findings are reported, never quietly repairedEvery Attention and Urgent item is quoted before it is touched. You approve the written quote first; that is the whole point of a diagnosis-first workshop.
Signed at QC before it leavesThe technician signs the sheet, it is countersigned at quality control, and you keep a copy with the two figures that matter: vent temperature and battery voltage.

Four steps, in this order, every time
Diagnosis-first is the whole method: measure, write it down, then price it. It is also why every job, gas filling included, is quoted in writing after the checkup.
We test before we quote
The free 30-point A/C and electrical checkup runs first, about 15 minutes, with a written report of what was measured.
You get the estimate in writing
The report says what was found. Gas filling, like everything else, is quoted in writing after the checkup, and nothing starts until you approve it.
No work starts until you approve
Nothing is opened up or replaced before you say yes to the estimate. If the diagnosis changes the scope, you hear about it first.
Repaired, then checked again
The approved work is done and the car is checked again before handover.
