In Singapore’s hot and humid weather, many homeowners wonder — should you leave your aircon on when stepping out for a short while, or turn it off completely? It may seem like a small choice, but it actually affects your electricity bill, aircon lifespan, and indoor comfort. Let’s find out what’s best for your aircon and your wallet.
The Common Misconception
Many people believe that turning the aircon off wastes energy because it takes more power to cool the room again. However, that’s not always true. If you’re away for more than 15 to 30 minutes, keeping the aircon running continuously can use more electricity than restarting it later.
In Singapore’s climate, where energy costs are rising, knowing when to switch off your unit can help you save money and reduce wear on your aircon system.
When You Should Turn It Off
If you’re leaving home for more than half an hour, it’s best to turn off your aircon. Even if the room gets warm, restarting it uses less power than keeping it on the entire time.
Also, switching it off gives your unit a break — protecting parts like the compressor and condenser coils from overworking. Over time, this can extend your aircon’s lifespan and lower the need for aircon repair services.
When You Can Leave It On
However, if you’re stepping out only for a few minutes — maybe to buy coffee or grab a parcel — it’s fine to leave the aircon on. Turning it off for such a short time won’t save much energy and might even cause temperature fluctuations when you return.
Still, make sure your aircon runs on energy-saving mode or set the temperature slightly higher (around 26°C). This helps reduce power use while keeping your room comfortable.
Use Smart Timers or Inverter Aircons
For even better control, consider upgrading to a smart aircon system or inverter aircon Singapore models. These units adjust cooling automatically and use less power.
With smart timers or Wi-Fi control, you can switch the aircon off remotely or schedule it to turn on before you return — saving energy while ensuring your home stays cool.
In short, if you’re stepping out briefly, leaving your aircon on at a higher temperature is fine. But if you’re gone for longer than 30 minutes, it’s smarter to turn it off.
This simple habit helps you save on electricity bills, reduce strain on your system, and keep your aircon running efficiently for years.
