Air conditioning is a lifesaver in humid and hot weather, but it can also be one of the biggest contributors to your electricity bill.
Many homeowners find themselves wondering how to save electricity of aircon without sacrificing comfort.
The good news is, there are practical, proven ways to enjoy a cool room and still keep your energy bill under control.
In this article, we’ll share aircon saving tips, explain which mode is best for AC to save electricity, and show you how small changes can help reduce your AC bill significantly.
Air conditioning accounts for a large percentage of household electricity usage, especially in warm and humid climates like Singapore.
Understanding why aircons use so much power helps homeowners take the right steps to improve efficiency and reduce costs, setting the stage for the energy-saving tips below.
Before diving into complex solutions, the simplest way to save electricity of aircon is by setting the right temperature.
In Singapore’s tropical climate, the optimal aircon temperature is typically between 25°C to 27°C.
When you lower the temperature too much (for example, setting it to 20°C), your aircon has to work extra hard to cool the room, which increases electricity usage.
By keeping the temperature moderate, you allow your unit to run more efficiently and lower your aircon electricity bill.
Pro Tip: Every 1°C increase in temperature can save up to 10% in energy consumption , that’s a big difference over time!
Many people don’t realize that which mode is best for AC to save electricity depends on how and when you use it. Most modern air conditioners come with several modes, cool, dry, fan, and auto.
Here’s a quick guide to help you choose wisely:
If your goal is to save electricity of aircon, the Dry Mode or Auto Mode are generally the best options for regular home use.
They prevent overcooling and minimize compressor activity, the part of the aircon that consumes the most power.
No matter how energy-efficient your aircon is, if it’s dirty, it will consume more power. Dust and debris clog the filters and block airflow, making the system work harder.
To save aircon electricity at home, make it a habit to clean the filters every two to four weeks.
You can do it yourself easily, just remove the filter, wash it with mild soap and water, and let it dry completely before reinstalling.
For a deeper clean, schedule professional aircon servicing every 3–6 months. Technicians can check for gas leaks, clean the evaporator coil, and ensure your unit is running smoothly.
This simple step not only improves cooling efficiency but also extends your aircon’s lifespan.
This might sound obvious, but it’s one of the most common mistakes homeowners make.
When cool air escapes through open doors or windows, your aircon has to work continuously to maintain the temperature.
By keeping your space sealed, you’ll significantly reduce AC bill and avoid unnecessary strain on the system.
You can also install weatherstripping or door draft stoppers to prevent leaks, a small investment that leads to big energy savings.
Another underrated energy-saving tip for aircon is managing the sunlight that enters your room.
Sunlight streaming through windows increases room temperature, forcing your aircon to cool harder.
Close your curtains or blinds during the hottest parts of the day, especially if your windows face west or south.
For even better results, use thermal curtains that reflect heat and keep your room cooler naturally.
Appliances like ovens, hair dryers, and computers release heat that can make your aircon work overtime.
If possible, use these devices less often during the hottest hours of the day or switch to energy-efficient versions.
Even small habits, like turning off lights when not needed, can help save electricity of aircon because every bit of reduced indoor heat means your cooling system can rest.
If your unit is over 8–10 years old, it might be time for an upgrade. Modern inverter air conditioners are far more efficient and can help reduce AC bill by up to 40%.
Inverter systems automatically adjust compressor speed to maintain consistent cooling without frequent start-stop cycles, which is where traditional aircons waste the most energy.
Look for models with a high NEA energy rating (4 or 5 ticks in Singapore) for the best long-term savings.
Want to save aircon electricity at home effortlessly? Use the timer function or invest in a smart thermostat.
Timers allow you to turn off your aircon automatically after you’ve fallen asleep or once the room reaches the desired temperature.
Smart thermostats take it a step further, they can learn your cooling habits, detect when you’re away, and optimize energy use automatically.
This ensures comfort when you need it, and savings when you don’t.
Here’s one of the simplest aircon saving tips: use a ceiling or standing fan to circulate cool air. This lets you increase your aircon temperature setting without feeling warmer.
Fans use far less power than compressors, so combining both helps maintain comfort while lowering your aircon electricity bill.
Instead of setting your aircon to 22°C, set it to 26°C and use a fan. You’ll stay just as comfortable and save a significant amount of energy.
Energy saving works best when everyone in your household is involved. Teach your family or housemates simple habits like turning off the aircon when leaving a room or closing windows during operation.
With everyone on board, your efforts to save electricity of aircon will have an even greater impact.
