Car AC service for Mogappair car owners
GM Car A/C Service is located in Kallikuppam, Ambattur (5.5 km from Mogappair, ~12–15 min drive via Golden Flats, Ambattur Industrial Estate Road & Kallikuppam link). We serve car owners from Mogappair (Golden Flats, Spartan School, Mogappair East & West Bus Terminus, Nolambur link) with diagnosis-first car AC gas filling that includes a leak check, compressor repairs, cooling coil replacements, and auto electrical diagnosis.
Local Driving Note: Dense neighborhood traffic between Mogappair East/West and Ambattur Estate means cars spend significant time at low engine RPMs. We test AC high/low pressure curves at both idle and 2,000 RPM to ensure consistent cooling. Pickup and drop may be available for confirmed service bookings across Mogappair East, West, and Nolambur.

Both figures are taken. An alternator can produce an acceptable voltage at idle and fall short under load, which is when the fault actually bites.
Diode rippleAC leakage from the alternator is measured in millivolts. High ripple cooks batteries and confuses electronics, and it is invisible to a simple voltage check.
Alternator belt and pulleyChecked as part of the charging system rather than as an engine item, because a glazed belt reduces output long before it starts squealing.
Charge warning lamp at key-on and runningThe lamp must behave correctly in both states. A bulb that never lights hides a charging fault until the car stops.

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.

My battery keeps going flat but it is new.
A new battery going flat points at the charging system or a parasitic drain, not at the battery. We take alternator output at idle and at 2,000 rpm, and measure diode ripple.
What is diode ripple and why check it?
It is AC leakage from the alternator, measured in millivolts. High ripple damages batteries and upsets electronics, and a simple voltage check will not reveal it.
