Car A/C
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.
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 →
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.
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.
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.

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.
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.
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.
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.
