Car AC service for Avadi car owners
GM Car A/C Service is located in Kallikuppam, Ambattur (8.5 km from Avadi, ~18–22 min drive via Chennai–Tiruvallur High Road (CTH Road) straight to Kallikuppam). We serve car owners from Avadi (Avadi Checkpost, HVF Estate, Avadi Railway Station, Karunakarachery and Nehru Nagar) with diagnosis-first car AC gas filling that includes a leak check, compressor repairs, cooling coil replacements, and auto electrical diagnosis.
Local Driving Note: Daily transit across CTH Road exposes vehicle cooling systems to heavy road dust, which quickly blocks cabin pollen filters and reduces evaporator airflow. If your AC blower seems loud but air delivery is weak, filter inspection is the first essential step. Free pick-up and drop anywhere in Chennai, on confirmed bookings, subject to slot availability.

R134a and R1234yf are never mixed. The type is read off the manufacturer's sticker before a hose is connected, not assumed from the model year.
Charge weight against specificationThe system is labelled with a charge weight in grams. We compare what comes out against what should be there, which tells you whether you have a leak or a previous overcharge.
Under, over or correctOvercharging cools worse than a correct charge, and it raises head pressure. The charge state is recorded as an observation, not inferred from how cold the vent feels.
Gas filling includes the leak checkThe price is quoted in writing after the free 30-point checkup and confirmed at the counter before work starts. If the gas has gone somewhere, refilling it without finding out where is money spent twice.

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.

Is my car R134a or R1234yf?
It is printed on a sticker under the bonnet, and we read it there before connecting anything. The two are never mixed.
My gas did not last the season. Why?
Refrigerant does not get consumed, so if it has gone it has leaked. The leak check is included with gas filling for exactly this reason, refilling without finding the leak spends the money twice.
