GM Car A/C Service is located in Kallikuppam, Ambattur (6.8 km from Kolathur, ~15–18 min drive via Retteri Junction Flyover & 200 Feet Inner Ring Road). We serve car owners from Kolathur (Retteri Lake Flyover, DRJ Hospital, Kolathur Main Road, Teachers Colony and Puzhal link) 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: Vehicles operating around Retteri Junction and Inner Ring Road experience heavy heat radiated from asphalt and dense truck traffic. If your AC cools acceptably in morning hours but fails in direct midday sun, condenser washing and pressure diagnostics are recommended.

Cooling at idle versus at road speed

A system that cools only when the car is moving has a condenser-airflow fault, not a gas fault. This single comparison redirects the whole diagnosis.

Condenser fin condition

Bent fins, blockage, road debris and insect packing all reduce heat rejection. We look at the fin face before touching the refrigerant circuit.

Condenser fan operates on demand

The fan must come on when the A/C is called for. A fan that does not run turns every stop in traffic into a loss of cooling.

The radiator and condenser sandwich

Leaves, plastic and dirt pack between the two and are invisible from above. Fan speed steps are checked where the vehicle has them.

The AC only cools when I am driving, not in traffic.

That is a condenser-airflow symptom, not a gas symptom. We compare cooling at idle against cooling at road speed, then check the condenser fan, the fin face and the debris packed between the radiator and condenser.

Does a dirty condenser really matter?

Yes. Bent fins, insect packing and trapped leaves all cut heat rejection, and the effect is worst exactly when you need cooling most.

The workshop is in Kallikuppam, Ambattur, so customers from neighbouring areas use it too: Villivakkam · Madhavaram · Redhills · Anna Nagar · Surapet.
