Quick Answer
The ideal AC temperature for saving electricity is 24–26°C. Setting the AC lower than this increases power consumption significantly without providing meaningful additional comfort. For every 1°C you raise the temperature above 22°C, you can save approximately 3–5% on your electricity bill.

AC Temperature vs Electricity Consumption
This table shows how each degree of temperature setting affects your power usage and monthly electricity bill. Bookmark this page for quick reference.
| AC Temperature | Electricity Usage | Comfort Level | Bill Impact | Visual |
|---|---|---|---|---|
| 18°C | Very High | Very Cold | ~40% higher than 24°C | |
| 20°C | High | Cold | ~25% higher than 24°C | |
| 22°C | Medium | Comfortable | ~12% higher than 24°C | |
| 24°C | Low | Ideal | Baseline (optimal) | |
| 26°C | Very Low | Slightly Warm | ~8% lower than 24°C | |
| 28°C | Minimal | Warm | ~15% lower than 24°C |
Key insight: The jump from 24°C to 18°C increases power consumption by approximately 40%. That is the difference between a ₹2,500 monthly bill and a ₹3,500 monthly bill for the same usage hours.
Why 24–26°C Is the Best Range
Three key reasons make 24–26°C the sweet spot for Indian homes. This range is recommended by the Bureau of Energy Efficiency (BEE) and verified by field technicians across the country.
Balanced Cooling
At 24–26°C, the AC removes humidity effectively while maintaining a comfortable indoor temperature. Most people feel comfortable in this range without needing blankets or feeling too warm.
Lower Electricity Consumption
Inverter ACs run at optimal compressor speed at 24–26°C, consuming 30–40% less power than at 18–20°C. The compressor does not need to overwork to reach an unrealistically low target.
Comfortable for Most Users
Studies in Indian households show 85% of users report comfort at 24°C. Below 22°C, many people experience dry skin, headaches, and cold-related discomfort, especially children and seniors.

How Temperature Affects Your Bill
Understanding the physics behind AC power consumption helps you make smarter temperature choices every day.
Lower Temperature = More Power
When you set the AC to 18°C, the compressor must work harder and longer to bridge the gap between indoor and outdoor temperatures. In Indian summers where outdoor temperatures reach 40–45°C, that gap is 22–27°C.
At 24°C, the gap is only 16–21°C. The compressor cycles more efficiently, draws less current, and reduces wear on internal components.
Each Degree Matters
Research by the Bureau of Energy Efficiency (BEE) shows that for every 1°C increase in thermostat setting above 22°C, power consumption drops by 3–5%.

Inverter AC vs Non-Inverter AC
Inverter ACs adjust compressor speed based on the temperature gap. At 24°C, they run at 40–60% capacity, saving significant power. Non-inverter ACs run at full power and cycle on/off, consuming more electricity regardless of the temperature setting.

Setting your AC at 24–26°C helps maintain comfort while reducing electricity consumption. This temperature range is optimal for Indian climates where outdoor temperatures regularly exceed 35°C.
Lower temperatures increase power usage without significant additional comfort. The body cannot perceive a meaningful difference between 22°C and 18°C, but the electricity meter certainly can.
“The best AC temperature to save electricity is around 24 degrees Celsius. Setting it between 24 and 26 degrees gives you the best balance of comfort and power savings. Every degree below 24 increases your electricity bill by 3 to 5 percent.”
