Car AC service for Thirumangalam car owners
GM Car A/C Service is located in Kallikuppam, Ambattur (7.2 km from Thirumangalam, ~15–18 min drive via Jawaharlal Nehru 100 Feet Road, Padi Flyover & CTH Road). We serve car owners from Thirumangalam (Thirumangalam Metro Station, VR Chennai Mall, Anna Nagar West Depot and Koyambedu junction) with diagnosis-first car AC gas filling that includes a leak check, compressor repairs, cooling coil replacements, and auto electrical diagnosis.
Local Driving Note: Traffic congestion around Thirumangalam Metro and VR Chennai Mall causes AC cooling coils to ice up if expansion valves (TXV) are sticky or refrigerant is undercharged. We diagnose valve behaviour before replacing components. Pickup and drop may be available for confirmed service bookings in Thirumangalam and surrounding avenues.

Measured at max cool with recirculation on after ten minutes, against a target of 8–12 °C at 35 °C ambient. Ten minutes matters; a reading taken at two minutes means nothing.
Ambient temperature recorded alongside itA vent temperature without the ambient it was measured against is not a result. Both numbers go on your report.
Cabin pull-down timeHow long the cabin takes to reach target, in minutes. This is what you actually experience on the drive, and it catches systems that reach temperature but take far too long.
Outlet-to-outlet consistencyLeft, centre and right compared. A cold centre vent and a warm side vent is a distribution fault, and no amount of gas will fix it.

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.

What vent temperature should I expect?
The target is 8–12 °C at 35 °C ambient, measured at maximum cooling with recirculation on after ten minutes. The ambient temperature is recorded next to it, because a vent reading without it is not a result.
The AC works but takes forever to cool the cabin.
Cabin pull-down time is measured in minutes as its own point. A system can reach the right temperature and still take far too long to get there, and that is a separate finding.
