GM Car A/C Service

Why GM Car A/C Service

Car A/C is what we are known for, and every job follows the same five steps: we measure before we quote and we quote in writing before any paid work starts.

What we do not do

We do not offer breakdown or roadside help, towing, body work or tyres.

What we provide

Every visit can start with a free 30-point A/C and electrical checkup that takes 15 to 35 minutes and ends with a written report. You then get a written estimate, and nothing paid starts until you approve it.

Free 30-point checkup with a written report. No obligation to have any work done.
Written estimate, approved first. Parts and labour are listed, and you say yes before paid work begins.
Parts at distributor cost. We show you the parts invoice. Old parts are returned on request, otherwise scrapped.
Bajaj Finserv EMI on bills of ₹10,000 or more, subject to lender approval.
Free pick-up and drop, free within 25 km of our Ambattur and Surapet workshops, on confirmed bookings, subject to slot availability. Outside 25 km, call us first; pick-up there may be chargeable.
Warranty on replaced parts: 10,000 km or 6 months. The exact term depends on the car brand and on whether the part fitted is OE or OEM, and it is written on your bill. There is no warranty on gas filling. Read the warranty.

Starting prices are published for two jobs only: gas filling from ₹1,199 and general service from ₹3,599. The final price is set after the free checkup. How we quote.

Our equipment includes a refrigerant recovery machine, line testers, and wrenches and mechanical tools that are mostly from INGCO.

EMI subject to lender approval, applicable terms and eligible services. Bajaj Finserv is the lender, not GM Car A/C Service.

How we service

We follow five steps on every job: listen, measure, quote in writing, repair and show, then check and follow up. The order never changes, so you always know what happens next.

Listen. You tell us the symptom, the car and when it started. We write it down before we touch the car.
Measure. The free 30-point A/C and electrical checkup records pressures, temperatures and voltages. You get the readings in a written report.
Quote in writing. The estimate lists parts and labour. Nothing paid starts until you approve it, and if the work changes we come back to you first.
Repair and show. We do the approved work, charge parts at distributor cost and show you the parts invoice. Old parts come back on request.
Check and follow up. We check the work again before handover and follow up afterwards. If a replaced part fails within its warranty term, bring the bill.

Choose an authorised service centre if you want work done under the car maker's own programme. Choose GM when the A/C is the problem and you want to see what was measured before you pay.
