Regular servicing keeps your AC cooling well and your electricity bill low — but prices differ depending on your unit type and the kind of service. Here's what AC servicing typically costs in Chennai in 2026.
Typical AC Service Costs in Chennai
| Service Type | Typical Cost (₹) |
|---|---|
| Split AC — general (dry) service | ₹400–600 |
| Split AC — wet / jet service | ₹500–800 |
| Window AC — general service | ₹350–500 |
| Window AC — wet / jet service | ₹450–650 |
| Deep chemical wash | ₹800–1,400 |
| Foam / anti-bacterial coil clean | ₹600–1,000 |
Dry Service vs Wet (Jet) Service — What's the Difference?
A dry service covers filter cleaning, a wipe-down, a gas pressure check, and an electrical inspection. It's fine for a unit that's serviced regularly.
A wet or jet service uses a pressurised water jet to deep-clean the evaporator and condenser coils. In Chennai's dusty, coastal climate, coils clog quickly — so a wet service every second or third visit restores cooling and efficiency far better. It's the one we recommend for most homes here.
What a Good Service Should Include
- Filter removal and cleaning
- Indoor and outdoor coil cleaning
- Drain pipe flushing (prevents water leaks)
- Refrigerant pressure check
- Tightening of electrical connections
- Outdoor fan and capacitor inspection
How Servicing Saves You Money
A dirty AC uses 10–25% more electricity than a clean one — that's ₹300–800 extra on a typical monthly bill. Two or three services a year usually cost less than what you'd waste on power from a neglected unit, and they catch small faults before they become expensive breakdowns.
