Why Chennai ACs Need Extra Care
Chennai runs ACs for 8–10 months a year, and its coastal humidity and salt-laden air corrode copper and aluminium coils, especially in areas near the beach like Besant Nagar, Thiruvanmiyur and ECR. Dust from construction clogs filters fast. The result: ACs lose cooling efficiency and develop gas leaks sooner than in inland cities.

Service Schedule for Chennai
With near-year-round use, service every 3–4 months and clean filters every two weeks in summer. Book a deep service before March, when demand peaks and technicians get booked out. Near the coast, ask for anti-corrosion coating on the outdoor coil and check copper pipes for green corrosion. For cooling problems, see our guide on why ACs stop cooling.
Choosing a Technician
Ask for gas pressure readings before agreeing to a refill — many "low gas" claims are really dirty coils. Confirm refrigerant type, whether leak repair is included, and get a service warranty (30–90 days). Find AC repair and service in Chennai on FindService.in. With high AC loads, have an electrician in Chennai check wiring and stabiliser capacity too.
