Chennai's extreme heat and high humidity put extra stress on air conditioning systems. Unlike cooler climates where AC usage is seasonal, Chennai residents depend on their AC units almost year-round. This makes regular maintenance not just recommended - it's essential.
After servicing thousands of AC units across Chennai, we've developed specific maintenance schedules that work best for our local climate conditions. Here's everything you need to know about AC service frequency in Chennai.
The Chennai Climate Challenge
Chennai's climate creates unique challenges for AC systems:
- High humidity: 70-80% humidity year-round increases condensation and moisture-related problems
- Extreme heat: Temperatures often exceed 40°C, forcing ACs to work harder
- Dust and pollution: Coastal dust and urban pollution clog filters faster
- Salt air: Coastal location causes faster corrosion of metal components
- Nearly year-round usage: Most ACs run 8-12 hours daily
