It’s no surprise that your air conditioner usage makes up more than half of your monthly electricity bill as you’re likely working from home in doing your part to curb the spread of the pandemic, which probably gets you worried about your next electricity bill.

Maybe you’ve already engaged a technician to service or repair your air conditioner but it’s back to living in a furnace after some time. What can you do?

Here are five ways to improve your air conditioner’s efficiency at no cost.

1. Keep curtains and blinds closed during the day, close off excess spaces.

 When you were young, your parents probably told you to close all the windows, curtains, and blinds so that you “don’t waste air-con”. There’s some truth to this. Keeping your curtains or blinds closed can keep some of the unwanted Malaysian heat from warming the inside of your home, as trapped heat means the air conditioning needs more power to keep your home cool. Choose white or light-coloured curtains and blinds as they are best at reflecting light and heat away from your home.

2. Clean your air conditioner’s indoor filter.

Dirt and dust will get trapped within your air-con’s filter as it keeps you cool. Another easy way to maintain its efficiency is to clean the filter on your own every two weeks. Just open the front grill and gently remove and vacuum the filter if it’s not too filthy.

If the filter is extremely soiled, wash it using a mix of mild soap and lukewarm water and let it dry completely on its own in a shady place away from sunlight – avoid using a hairdryer to speed up the process as well as any cleaning agents either.

It can be troublesome (and slightly dangerous if you’re not careful) to do this on your own. For Daikin air conditioner owners, you can now book an air conditioner cleaning service via the Go Daikin App’s new feature, Go Clean. to enjoy 10% off (capped at RM100) your first cleaning service with the launch promo code: GOCLEAN10IP.

3. Avoid using heat-generating equipment in the day.

You may want to use heat-generating appliances such as the oven, dryer, or dishwasher less often during the day. Any heat produced by these appliances makes it more difficult for your air conditioning to keep your home cool. Where possible, use these appliances when the sun is down, so your air conditioner won’t have to work as hard.

4. Keep the fans circulating (no, you did not read this wrongly!).

You may balk at this – after all, why is there a need to switch on the fan while you’re using the air-con? Think of it this way – the fan complements the air-con. If the air in your home circulates freely, you’ll feel cooler, even when the temperature inside is the same. Adding ceiling fans to your home is a simple and effective way to circulate air and keep things cooler.

5. Make use of your air conditioner’s energy-saving settings.

What is the most efficient way to run an air conditioner? The best way to lower your electricity bill is to switch on the energy or power saver mode on your air conditioning unit. This mode will provide ample cooling for your home without extra pressure on the air conditioner.

When you’ve tried everything, and it’s still heat central at home…


Then it’s probably maintenance time for your air conditioner. Or if you just completed your air conditioning unit’s maintenance, it’s time to switch to professional technicians.

Some frequently asked questions about AC efficiency

What is the difference between inverter and non-inverter air conditioners when it comes to cost savings?

It’s extremely important to buy an air conditioner that’s an inverter type. Inverter air conditioning units are able to regulate its compressor motor. Once your room reaches the set temperature, the inverter air conditioner is able to lower its motor speed to save power, and in turn, a cheaper electricity bill. Non-inverter air conditioners can only go full speed or stop, so when it hits the desired temperature it will turn off. As such, it needs to constantly switch on and off to maintain your set temperature.

What is a good energy efficiency ratio for air conditioners? How is AC efficiency calculated?

You’ve probably seen a red sticker affixed to electrical appliances when shopping. The Malaysia Energy Commission gives a star rating for electrical appliances, with more stars meaning more energy savings.

For an air conditioner to get a 5-star rating, it depends on its Cooling Seasonal Performance Factor. This is the ratio of how much heat the air conditioner can remove from indoor air when used for cooling in active mode, to the unit’s annual power consumption in the same period.
