Complete Guide to Car AC Service in India — When to Service, What's Included, Costs
Why Car AC Service is Critical in India
Indian summers are brutal. Delhi NCR regularly sees temperatures above 45°C between April and June. A faulty car AC doesn't just cause discomfort — it affects driving concentration and safety. Regular AC maintenance also prevents minor issues from becoming expensive compressor failures.
How Car AC Works (in Simple Terms)
Your car's AC system uses a refrigerant gas (R134a or R1234yf in newer cars) that cycles between liquid and gas states to absorb heat from inside the cabin and release it outside. Key components include the compressor, condenser, evaporator, expansion valve, and receiver-drier.
When Should You Service Your Car AC?
- Annually — before summer starts (March–April is ideal in Delhi)
- When cooling is noticeably weaker than before
- When you hear unusual noises when AC is ON (compressor clutch issues)
- When there's a musty or foul smell from the vents
- When the AC takes very long to cool the cabin
- Every 2 years minimum for refrigerant gas top-up (regas)
