With Singapore’s heat, most households run their aircon for hours every day. The challenge? Staying comfortable without watching electricity bills climb every month. One of the easiest ways to manage this is choosing the right room temperature. But what’s the ideal setting for both comfort and savings?
Here’s a simple breakdown that helps Singapore homeowners understand how temperature settings influence cooling costs and aircon performance.
What Temperature Does Singapore Recommend?
The National Environment Agency (NEA) recommends setting your aircon at 25°C or higher. This isn’t just a random suggestion; there’s real reasoning behind it:
- Your aircon consumes significantly more energy for every degree below 24°C.
- Singapore’s humidity makes lower temperatures unnecessary once moisture is removed.
- Aircons work more efficiently when they don’t have to hit extremely cold settings.
For many households, 25°C – 27°C strikes a balance between comfort and energy savings.
Why Lower Temperatures Lead to Higher Bills
Cooling from 26°C to 22°C may feel nice, but it forces the compressor to work much harder. That means:
- Higher energy consumption
- Faster component wear
- More frequent aircon repair in Singapore needs
- Greater risk of the outdoor unit overheating

Best Temperature Ranges for Different Rooms
Different spaces in your home may need slightly different settings depending on usage.
Living Rooms
25°C–26°C works well since it balances comfort with power savings.
Bedrooms
Most people prefer slightly cooler temperatures when sleeping. Try 24°C–25°C plus a fan for consistent airflow.
Home Offices
Electronics generate heat, so 25°C generally feels comfortable without overcooling.
How Humidity Affects Comfort at 25°C
Singapore’s humidity often makes people set their aircon lower than necessary. But once moisture is removed from the room, 25°C can feel surprisingly cool.
If your unit isn’t reducing humidity properly, there could be a servicing issue. This article explains common warning signs: How Do I Know if My AC Needs Servicing in Singapore?
Tips to Stay Cool Without Lowering the Temperature
Here are simple habits that help maintain comfort while keeping energy use low:
1. Use a Fan Together with the Aircon
Fans improve circulation and make 25°C feel cooler.
2. Keep Doors and Windows Closed
Prevent warm outdoor air from entering and forcing the aircon to work harder.
3. Clean Filters Regularly
Dirty filters restrict airflow and make cooling inefficient.
4. Avoid Heat-Producing Appliances
Cooking, ironing, or using the oven while the aircon runs increases room temperature.
5. Ensure Proper Installation

What if 25°C Still Feels Too Warm?
If you’re setting the temperature correctly and the room still feels warm, the issue might not be the thermostat. Some possibilities include:
- Refrigerant running low
- Blocked drainage
- Clogged coil
- Outdoor unit overheating
- Faulty installation

Saving Electricity Isn’t Only About Temperature
While setting the aircon at 25°C saves energy, it works best when combined with:
- Properly maintained units
- Regular cleaning
- Timely aircon services in Singapore
- Correct room insulation
- Smart use of fans
- Avoiding extreme temperature changes
Homes that follow these practices not only reduce bills but also face fewer breakdowns, especially during peak humidity months, when 24-hour aircon services become a lifesaver for emergency situations.
