🌡️ Best Temperature Settings for Comfort and Savings (Singapore Context)

In Singapore’s hot and humid weather, the aircon is a daily essential for comfort. But finding the ideal temperature can be tricky — set it too low and your bills climb fast, set it too high and you’ll be left sweating.

The key is to balance comfort and efficiency. Here’s what you need to know about the best temperature settings for Singapore homes.

The Sweet Spot: 24°C to 26°C

According to the National Environment Agency (NEA), the most energy-efficient temperature for air-conditioning in Singapore is 25°C.

This range provides:

• Comfortable cooling for most households

• Lower energy use (each degree lower adds about 5–10% to your bill)

• Better humidity control without overworking your compressor

Tip: Set your aircon at 25°C, use the fan mode to circulate air, and keep doors and windows closed for faster cooling.

Why Going Too Low Wastes Energy

Many people think setting their aircon to 18°C cools the room faster — but that’s a myth. Your aircon cools at the same rate no matter the setting; it just keeps running longer.

When you set the temperature too low:

• The compressor runs continuously, consuming more electricity

• Indoor humidity drops excessively, leading to dry skin and sore throat

• Components wear out faster, shortening your aircon’s lifespan

Adjusting for Different Times of Day

Daytime: If the sun heats your room, use 24°C–25°C and close the curtains to block heat.

Nighttime: Try 26°C or Sleep Mode. Your body’s temperature drops while you sleep, so you won’t need the same level of cooling.

Tip: Use a timer to turn off your aircon before dawn — this can reduce your electricity cost by up to 15%.

Bonus: Use Your Remote Smartly

Most modern aircons in Singapore come with these helpful settings:

• Eco Mode: Saves power by adjusting fan speed and compressor usage

• Fan Mode: Keeps air moving without additional cooling

• Sleep Mode: Gradually raises temperature through the night for comfort

These simple features help you stay cool while cutting down on energy costs.
