AC Service in Chennai: How Often, What It Should Include, and What It Costs

An AC in Chennai works harder than almost anywhere in India: nine months of heat, coastal humidity, and fine dust from construction on every street. A unit that is not serviced loses 10–20% cooling capacity a year and uses more electricity doing it.

How often

Twice a year: before summer (February–March) and after the North-East monsoon (December). Homes near main roads or construction sites may need a third service.

What a proper wet service includes

• Indoor unit: filters washed, evaporator coil foam-cleaned and rinsed, blower cleaned, drain line flushed.
• Outdoor unit: condenser coil water-jet cleaned, fan checked, capacitor and contactor checked.
• Gas pressure checked with gauges — not guessed.
• Outlet temperature measured after service (should be 8–12°C below room temperature).

A "service" that is just a wipe and a filter rinse is not a service.

What it should cost in 2026

A standard split AC wet service in Chennai is ₹500–800 per unit. Gas top-up, if needed, is extra and depends on the refrigerant (R32 and R410A cost more than the older R22). Be wary of anyone who says you need gas every time — a properly installed AC should not lose gas unless there is a leak, and a leak should be found and fixed, not topped up.

Annual maintenance for offices and clinics

For offices in Anna Nagar and Kilpauk we run AMC contracts: scheduled services, priority repair visits and a log per unit. It is cheaper than emergency calls in May.
