How Much Is the Electricity Cost for an Aircon in Singapore
A fully running air conditioner rated at 12,000 BTU, which has enough cooling power to service an HDB flat with floor area ranging between 350 and 650 square feet, will consume around seven kilowatts of electricity per hour. Presently, homeowners in Singapore are eligible for electricity at a regulated tariff rate. According to the SP Group, the tariff rate for electricity without GST is $29.88 cents/kWh from July to September 2024. With GST, electricity costs 32.57 cents/kWh. You can easily extract your aircon’s estimated monthly cost of energy consumption from these values.

Tips for Lowering Your Aircon’s Electricity Cost in Singapore
Thankfully, there are things you can do to effectively minimize your air conditioner’s critical impact on your electricity bill every month. Here are some of them:
Energy Efficiency
1. Invest in an inverter aircon. By investing in a reliably energy-efficient and modern air conditioning system, you won’t really have to give up your personal comfort since you can cool your home for less. The downside is that you will be spending a lot of money upfront. Inverter-type air conditioners have superior energy-efficiency capabilities; unlike traditional air conditioning units that use electricity-guzzling on-and-off cycles, inverter aircons have the ability to regulate compressor motor speed to maintain the desired room temperature.
2. Pay attention to the National Environment Agency’s tick rating system when choosing an air conditioning unit. The NEA assigns energy labels on residential air conditioners to assist buyers in identifying energy-efficient models. 4-tick and 5-tick labels are given to air conditioners that the NEA deems to be most energy efficient.
Aircon Settings
3. Take advantage of the AC timer settings. Typical aircon timers have built-in settings that correspond to Sleep Mode and Energy-Saving Mode. You should fully make use of them. They make your life infinitely easier and help you cut energy costs. For example, you can always set your AC to automatically turn off an hour before you are set to leave your flat in the morning; the room temperature stays low during the early morning hours, which means you don’t need to fully run the air conditioner at all.
4. As much as possible, stick to a room temperature setting of 25 degrees Celsius, which is absolutely already comfortable. A windowless room in a shaded lower floor of an HDB building can even get by with 26 or 27 degrees Celsius. In fact, raising the thermostat setting by two degrees is barely noticeable in terms of individual comfort level, but it has a considerable impact on lowering your air conditioner’s energy consumption.
Monitoring
5. Use the SP Group app to monitor your electricity usage. You can download the app from Google Play if you have an Android device and the Apple store if you use an iPhone. The more aware you are of your real-time usage patterns, the more conscious you will be in conserving electricity.
6. Regularly maintain your air conditioning unit. A dirty and clog-ridden air conditioner has a significantly reduced power capacity, which means you are wasting electricity to run an ill-maintained unit that needs to be overworked in order to cool your home. Try to clean the air filters, fan coil, and fins at least once a month. Empty the drain tray and unclog the drain pipe, too. Regular servicing of your AC is key to maximizing its cooling performance–and saving electricity.

Notes on the Cost of Electricity from Aircon Usage in Singapore
A typical household air conditioner in Singapore costs an average of $0.25 to 0.35 to run every hour. Depending on the size of the flat, the type of air conditioning unit, and the cooling needs of the household, electrical spending towards air conditioning varies. And of course, there are always minor changes you can do to cut your aircon’s consumption of electricity.

Conclusion: How to Reduce Aircon Electricity Costs in Singapore
Running an air conditioner in Singapore can significantly impact your monthly utility bill, especially with a standard 12,000 BTU unit consuming up to 7 kWh per hour. At the current SP Group tariff rate of 32.57 cents per kWh (inclusive of GST) for July to September 2024, continuous use could cost homeowners $20 to $35 or more per month per unit, depending on usage patterns and efficiency.
However, by making smarter choices, you can maintain comfort while keeping costs under control. Energy-efficient inverter aircons, especially those with 4-tick or 5-tick NEA energy labels, offer long-term savings despite higher upfront costs. Simple habits—like setting your thermostat to 25°C, using sleep or timer modes, and avoiding overcooling—can dramatically reduce energy consumption.
Regular aircon maintenance, such as cleaning filters and clearing drain pipes, ensures optimal performance and prevents wasteful energy use. Additionally, monitoring your usage through the SP Group app helps you stay aware and proactive about your electricity consumption.
For readers looking to cut aircon electricity costs in Singapore, these practical steps—from choosing efficient models to optimizing settings and maintaining units—are key to achieving both comfort and savings. With rising energy demands and living costs, adopting these energy-saving tips is not just economical, but essential for sustainable living.
