Air conditioning has become essential for comfort in India's hot climate, but it's also one of the biggest contributors to high electricity bills. Many households spend 40-60% of their monthly electricity budget on AC usage alone. The good news? Setting the right temperature can significantly reduce your costs without sacrificing comfort.
The temperature you set on your AC thermostat directly impacts power consumption. A difference of just 2-3 degrees can result in substantial savings over time. Understanding the optimal temperature range recommended by energy experts can help you maintain a comfortable indoor environment while keeping electricity bills under control. Use our AC Bill Calculator to estimate your potential savings.
Electricity Bill Impact at Different Temperature Settings
| Temperature Setting | Power Consumption (kW/hr) | Daily Cost (8 hrs) | Monthly Cost | Savings vs 22°C |
|---|---|---|---|---|
| 22°C (Very Cold) | 1.8-2.0 kW | ₹72-80 | ₹2,160-2,400 | Base (0% savings) |
| 24°C (BEE Recommended) | 1.4-1.6 kW | ₹56-64 | ₹1,680-1,920 | ₹480-480 (20% savings) |
| 26°C (Maximum Efficiency) | 1.2-1.4 kW | ₹48-56 | ₹1,440-1,680 | ₹720-720 (30% savings) |
| 28°C (With Ceiling Fan) | 1.0-1.2 kW | ₹40-48 | ₹1,200-1,440 | ₹960-960 (40% savings) |

Government & BEE Recommendations
Bureau of Energy Efficiency (BEE) Guidelines
The Bureau of Energy Efficiency, under the Ministry of Power, Government of India, officially recommends 24°C as the default temperature setting for air conditioners. This recommendation is based on extensive research on energy efficiency and human comfort levels. Learn more about How AC Star Ratings Impact Cost to maximize your savings.
- Default AC temperature should be set to 24°C
- Optimal range for most Indian climates: 24-26°C
- Can provide 20-30% energy savings compared to 18-20°C settings
- Maintains comfortable indoor environment for majority of users
The BEE's recommendation is not arbitrary – it's based on the principle that 24-26°C provides the best balance between human comfort and energy efficiency. This temperature range aligns with the natural comfort zone for most people in tropical and subtropical climates like India. Use our AC Tonnage Calculator to determine the right capacity for your room.
How Temperature Affects Power Consumption
The Science Behind AC Energy Usage
For every degree you lower the AC temperature below 24°C, power consumption increases by approximately 6-8%. This exponential increase happens because the AC compressor has to work harder to maintain lower temperatures. Calculate your exact consumption using our AC Bill Calculator.
❌ High Consumption (18°C)
- • Power usage: 1.8-2.2 kW per hour
- • Daily cost (8 hours): ₹72-88
- • Monthly cost: ₹2,160-2,640
- • 40-50% higher than optimal setting
✅ Optimal Consumption (24°C)
- • Power usage: 1.2-1.5 kW per hour
- • Daily cost (8 hours): ₹48-60
- • Monthly cost: ₹1,440-1,800
- • BEE recommended setting
Real Example: A 1.5-ton inverter AC running 8 hours daily at 20°C consumes approximately 12-15 units more per month compared to the same AC at 24°C. At ₹5 per unit, this means an additional cost of ₹600-750 monthly! Learn How to Calculate AC Electricity Bill for detailed calculations.
Best AC Temperature Range for India
Optimal Setting
BEE recommended temperature for best balance of comfort and efficiency
Comfortable
Slightly higher savings, suitable for most people with ceiling fan
Maximum Savings
Highest efficiency, ideal with dehumidifier mode in humid areas
Climate-Specific Recommendations:
🌡️ Hot & Dry Regions (Delhi, Rajasthan)
24-25°C works best. Low humidity makes slightly higher temperatures comfortable.
🌊 Hot & Humid Regions (Mumbai, Chennai)
25-26°C with dry/dehumidifier mode for optimal comfort and efficiency.
Tips for Saving More Electricity
Use Ceiling Fan
Running a ceiling fan with AC at 26°C feels like 23°C and saves significant energy. This combination is perfect for Indian homes.
Regular AC Maintenance
Clean filters monthly and service AC annually to maintain optimal airflow and cooling efficiency. Dirty filters can increase consumption by 15%.
Seal Air Leaks
Prevent cool air escape by sealing gaps around doors and windows. Use weather strips and door seals.
Block Sunlight
Use blackout curtains or blinds to reduce heat load during peak sun hours (12 PM - 4 PM).
Inverter AC Benefits
Inverter ACs with 5-star rating provide maximum efficiency at any temperature. They adjust compressor speed automatically for better savings.
Use Timer Function
Set AC to turn off 1-2 hours before waking up to save energy. Use sleep mode for gradual temperature increase.
Advanced Energy Saving Strategies
Smart AC Modes
- Auto Mode: Adjusts temperature automatically
- Dry Mode: Removes humidity efficiently
- Sleep Mode: Gradually increases temperature
Timing Strategies
- Pre-cool rooms before peak hours
- Avoid 12PM-4PM peak electricity hours
- Use night setback temperatures
