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

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

On a booked slot View All Services

Vent temperature at maximum cooling

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 it

A vent temperature without the ambient it was measured against is not a result. Both numbers go on your report.

Cabin pull-down time

How 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 consistency

Left, 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.

Which is the best car AC service centre near Thirumangalam?

GM Car A/C Service in Ambattur (7.2 km from Thirumangalam) is an established car AC workshop in the area. Free pick-up and drop anywhere in Chennai, on confirmed bookings, subject to slot availability. Call +91 8428000085.

Do you pick up cars from Thirumangalam for AC repair?

Yes. Free vehicle pick-up and drop is available from Thirumangalam and nearby areas. Call or WhatsApp +91 8428000085 to schedule at your convenience.

My car AC stopped working near Thirumangalam — what should I do?

Call GM Car A/C Service at +91 8428000085. We offer free vehicle collection from Thirumangalam. Our technicians will diagnose the exact cause — low refrigerant, compressor fault, or electrical issue — and fix it once you approve the quote.

What is the 1-Year AC Care Plan?

GM Cool Care Essential is ₹2,999 a year and covers 2 workshop visits over 12 months: one A/C gas refill, one Essential Service, and the free 30-point A/C and electrical checkup at every visit, plus priority booking and 5% off parts. Free pick-up and drop anywhere in Chennai, on confirmed bookings, subject to slot availability, for plan customers and walk-ins alike. Call +91 8428000085 to activate.

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.

The workshop is in Kallikuppam, Ambattur, so customers from neighbouring areas use it too: Anna Nagar · Mogappair · Avadi · Padi.

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