Summer heat can feel unbearable, and while the air conditioner offers relief, running it nonstop can take a toll on your electricity bill. So, the big question is: What’s the right temperature for your AC in the summer?
Experts recommend setting your air conditioner between 24°C and 26°C for the perfect balance of comfort and energy savings. Within this range, you can enjoy a cool escape from the heat without overspending. Of course, the “ideal” setting can still vary depending on your age, health, and personal comfort level.
In this blog, we’ll break down how to find the sweet spot for your AC - keeping both your body and your wallet happy.
Why Setting the Right AC Temperature Really Matters?
The temperature you set on your AC does more than decide how cool your room feels - it directly affects your health, energy bills, and the environment.
When you set the AC too low, like 18°C, the system runs at full force. This drives up electricity costs, wastes energy, and increases your carbon footprint. At the same time, such extreme cold can leave you with dry skin, muscle stiffness, and disturbed sleep.
On the other side, setting your AC too high, around 30°C, defeats the purpose of cooling altogether. You’ll still feel hot, uncomfortable, and may even face heat-related health risks.
That’s why finding the right balance matters. A moderate setting not only keeps you comfortable but also helps you save money and use energy more responsibly. It’s a small change that creates a big impact on both your lifestyle and the planet.
What’s the Right Temperature for Your AC in Summer?
During the hot summer months, finding the right air conditioner temperature is all about balancing comfort with energy efficiency. Here’s an overview of different AC temperatures:
| Temperature (°C) | Comfort Level | Impact on Bills | Health Notes |
|---|---|---|---|
| 18–20°C | Too cold | Very high | Can cause stiffness, dryness |
| 22–23°C | Cool | High | May disrupt sleep |
| 24–26°C | Balanced | Moderate | Ideal for most people |
| 27–28°C | Warm | Low | Comfortable with fan |
| 30°C+ | Too hot | Very low | Risk of heat stress |
Note: The temperature can be subjective on the basis of situation, person and environment.
Ideal AC Temperature in Bangladesh
Energy experts in Bangladesh recommend setting your AC at 25°C (78°F). This temperature aligns with the country’s average climate of around 26°C and gives a cool contrast to the body’s 37°C. It ensures comfort without overloading your AC or increasing electricity bills.
Since weather and humidity levels vary, you may need small adjustments. On humid days, lowering the temperature slightly helps maintain comfort, while on normal days 25°C is the perfect balance for comfort and savings.

Factors to Consider When Setting Your Summer AC Temperature
Before you set your AC, it’s important to understand what actually affects the “right” temperature. Things like humidity, room size, and the comfort needs of your household all play a role. By balancing these factors with a few smart habits, you can create a cooler, healthier home environment while keeping energy costs under control.
Here’s a table explaining the key factors and practical tips to help you set the best summer AC temperature:
| Factor | Best Practice | Quick Tip |
|---|---|---|
| Comfort | Kids/elderly: ~26°C, adults: ~24°C | Start at 24–26°C, adjust 1°C as needed |
| Heat & Humidity | Hot/humid days need cooler (24–25°C) | Use ceiling fan for wind-chill effect |
| Energy | Efficient range: 25–28°C | Use timers/automation when away |
| Health | Avoid extremes (too cold/too hot) | Moderate cooling = better sleep & breathing |
| Costs & Maintenance | Very low temps overwork AC | Service unit, clean filters, block sunlight |
The required AC temperature may vary depending on the brand, type, and room environment. For example, an LG AC may provide comfortable cooling at 25°C, while some local AC models may need to be set at a lower temperature, such as 18°C, to achieve similar results.
Smart Tips for Using Your AC in Summer
Staying cool doesn’t always mean running your AC at full blast. A few smart habits can make your AC work better, lower your bills, and keep your home comfortable.
Block sunlight: Close curtains or blinds during the hottest hours so your AC doesn’t work harder than it should.
Set 24–26°C and adjust slowly: Start in this range and change by 1°C if needed. It saves energy and keeps you comfy.
Use ceiling fans: Fans spread cool air around and make the room feel cooler, even at higher AC settings.
Try timers or smart controls: Let your AC switch off when you’re away and cool the room before you return.
Clean and service regularly: A clean filter and well-maintained AC cool faster, use less energy, and last longer.
