Before you compare prices: car AC ≠ home AC
Search "AC gas filling cost Chennai" and you'll see ₹2,500–2,800 — those are home split-AC prices from platforms like NoBroker and Urban Company. A car AC uses a far smaller refrigerant charge. At GM Car A/C Service, car AC gas filling is ₹1,500 fixed, including a full leak check. If a workshop quotes you home-AC money for a car, walk away.

Common AC Symptoms — What They May Indicate
These are possible causes only, not a diagnosis of your specific car. A technician should confirm the actual fault before any repair.
| Symptom | Possible cause | Recommended check |
|---|---|---|
| AC blows warm or lukewarm air | Low refrigerant charge, compressor clutch not engaging, or a blocked condenser | Refrigerant pressure check and compressor clutch test |
| Weak airflow from the vents | Clogged cabin filter, blower motor fault, or a restricted evaporator | Cabin filter inspection and blower motor test |
| AC cools, then stops cooling | An electrical relay fault, an overheating compressor, or intermittent wiring | Electrical circuit and relay diagnosis |
| Musty smell from the AC vents | Microbial buildup on the evaporator or a blocked condensate drain | Evaporator and drain-line inspection |
| Hissing or gurgling sound near the AC lines | A possible refrigerant leak or low charge | Leak detection test |
| Loud noise from the compressor area | A worn compressor clutch bearing or low lubricant | Compressor inspection |
| Ice forming on AC lines or the evaporator | An overcharged system or restricted airflow | Full system pressure check |
What Moves the Repair Estimate
Beyond the fixed gas-filling price, every other AC repair estimate depends on several factors: the vehicle model and how accessible its AC components are, the part brand and availability for that model, labour complexity for the specific fault, and any existing damage found once the system is opened up. Two cars with the same symptom can have different costs because the underlying part, labour time or damage extent is different. That is why compressor, coil, condenser and electrical work are quoted only after inspection — never guessed in advance.
