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, 15 to 35 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.
Serving north and west Chennai from Ambattur
The workshop is at 12A, Gangai Amman Kovil Street, Kallikuppam, Ambattur. These pages cover what we see most often in each area.
Before you book
Is the checkup really free, or is there a diagnosis charge?
The A/C, electrical and general checkup is free, with nothing to pay and no obligation to have the work done. We inspect first, explain what we found, and share the estimate before any paid work starts. It takes 15 to 35 minutes on a booked slot and you leave with a written report. Call +91 88893 60888 to book a slot.
What is the A/C Gas + Airflow Refresh?
Gas filling with a leak check, plus the cabin filter and vent airflow service. What it costs depends on the car: one with front and rear A/C takes more gas, and a cabin filter we have to order for the model costs more than one we stock. The counter confirms the total before the work starts.
How much does car AC gas filling cost in Chennai?
Gas filling starts from ₹1,199. The final figure depends on how much gas has gone, whether there is a leak to repair first, and whether your car has one A/C module or two. We run the free 30-point checkup, then give you the figure in writing before any paid work. Call +91 88893 60888 and we can tell you what your car is likely to need.
Why is my car AC not cooling properly?
Poor car AC cooling can result from low refrigerant, a gas leak, a cabin-filter restriction, compressor, condenser, cooling-coil or electrical faults. GM Car A/C Service diagnoses the fault before recommending repair work. See what causes weak A/C cooling
