If you’ve ever wondered what temperature to set air conditioner in summer at night, you’re not alone. We’ve all had those sticky nights where we toss and turn the AC on and off, wondering whether it should be cool enough to sleep but not so cold that it spikes the electricity bill.
After trying different settings ourselves and checking Bureau of Energy Efficiency (BEE) recommendations,, here’s a simple solution that balances comfort and energy savings.

The range for ideal sleeping temperature for AC during Indian summer nights is 24°C to 26°C (75°F to 78°F) for energy savings.
If you want cooler comfort, you can go down to 20°C to 22°C (68°F to 72°F), but this will increase your electricity usage
Keeping the AC on 24°C and using a ceiling fan to circulate air is the most energy-efficient choice for most Indian homes.
| Time of Day | Ideal Temp (°C) | Fahrenheit Equivalent |
|---|---|---|
| Night (sleeping) | 20–22°C | 68–72°F |
| Day (home) | 24–26°C | 75–78°F |
| Away from home | 28°C | 82°F |

Why Setting Your Thermostat Right Matters
Setting your air conditioner too low at night may feel good, but it increases your power bill and puts extra strain on your AC.
According to the BEE (Bureau of Energy Efficiency), keeping your AC at 24°C can help you save up to 6% on electricity for every 1°C increase from a lower setting.
Pro tip: In most Indian cities, setting your thermostat at 24°C during the day and around 22°C at night is a good balance between comfort and energy savings.
Why 67°F at Night Feels Just Right
The human body naturally cools down during sleep. For many people in humid Indian cities like Mumbai, Chennai, or Kolkata, 22°C at night feels just right for quick sleep without feeling too cold.
In hot and dry areas like Delhi, Jaipur, or Hyderabad, you might prefer 24°C with a fan to avoid overcooling.

Smart Tips for Better AC Efficiency at Night
Here’s what I’ve learned over time (and from some hot mistakes):
#1. Use a programmable thermostat
Set it to drop at night and automatically adjust the temperature based on your schedule.
#2. Keep windows and blinds closed during the day
This retains cool air more effectively and keeps your indoor temperature stable.
#3. Replace air filters monthly in summer
In Indian conditions, dust builds up faster, blocking airflow.Dirty filters hamper air circulation, thereby making your air conditioning system less effective.
#4. Try humidity control
If you live in coastal cities, use the AC’s “dry mode” to reduce humidity, making the air feel cooler.
