Car A/C
What is R134a and R1234yf car AC refrigerant?
Car A/C refrigerant is commonly called AC gas. The technician checks the vehicle’s A/C system and confirms the suitable service before filling begins. Published gas-filling prices are ₹1,500 for a single module and ₹2,200 for a double module, including a leak check.
How do I know if my car AC compressor is failing?
Signs of a failing car A/C compressor can include weak or warm airflow, loud clicking or grinding when the A/C is on, a clutch that does not engage, oil stains near the compressor, or intermittent cooling. GM diagnoses the fault before recommending repair or replacement. Learn about compressor repair →
What causes car AC to smell musty or bad?
A musty or bad smell from car AC is usually caused by mould or bacteria growing on the evaporator coil or in the cabin air filter, stagnant water in the drain pan, or a dirty air filter. At GM Car A/C Service, we perform a complete AC sanitisation and filter replacement — eliminating odour at the source, not masking it.
How long does car AC gas (refrigerant) typically last?
In a healthy, leak-free AC system, refrigerant can last the lifetime of the vehicle. If your car needs frequent gas refills (every 1–2 years), it indicates a leak in the system. At GM Car A/C Service, we always perform a full leak check before any gas filling — fixing the leak first ensures your refrigerant lasts and you don't waste money on repeat refills.
What is included in a full car AC service at GM Car A/C Service?
Car A/C service begins with diagnosis of the cooling concern. Depending on the fault, this can involve gas filling with a leak check, compressor, condenser, cooling-coil, filter or A/C electrical checks. Call +91 8428000085 to discuss your vehicle and issue.
Electrical and general service
Do you also do auto electrical repairs?
Yes. In addition to car AC service, GM Car AC Service in Chennai provides comprehensive auto electrical service including battery testing, alternator diagnosis, wiring fault repair, AC compressor relay, and blower motor repair — all handled in-house at our Ambattur workshop. Call +91 8428000085 for a diagnosis.
How often should I service my car?
Most cars benefit from a periodic service every 6 months or 5,000–10,000 km, depending on your vehicle and driving conditions. Share your model and last service date and GM will advise the right schedule.
Do you service luxury and SUV vehicles?
Yes. GM is a multibrand workshop servicing hatchbacks, sedans, SUVs and luxury cars. Share your make and model and we will confirm the appropriate diagnosis and service.
What kind of spare parts do you use?
GM uses quality parts suited to your vehicle and the repair. The part options and pricing are explained in your estimate so you can decide before work begins.
What are the warning signs my brakes need service?
Squealing or grinding noise, a soft or vibrating pedal, longer stopping distance, or a brake warning light all indicate it is time for a brake inspection. Do not delay — GM diagnoses the cause before recommending work.
How can I keep my car battery healthy?
Drive regularly, keep terminals clean, and get the charging system checked if starting feels slow. GM offers battery testing and replacement to confirm whether it is the battery or the alternator.
Why does the check-engine light come on?
A check-engine light can point to sensor, emission, fuel or ignition issues. GM runs computer scanner diagnostics to read the fault codes and identify the real cause before any repair.
