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 (₹1,500 single / ₹2,200 double module with 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.

Every service below is available to Avadi drivers, on any make.

Type confirmed from the bonnet sticker first

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 specification

The 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 correct

Overcharging 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 is a fixed price, with the leak check included

₹1,500 for a single module and ₹2,200 for a double module, leak check included. If the gas has gone somewhere, refilling it without finding out where is money spent twice.

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.

The workshop is in Kallikuppam, Ambattur, so customers from neighbouring areas use it too: Ambattur · Thirumangalam · Korattur · Mogappair.

Call or WhatsApp before travelling to confirm slot availability and whether pickup and drop can be arranged for your booking.
