Electricity is an essential part of daily life, but excessive use can take a toll on your finances and the environment.

One of the biggest energy-consuming appliances is air conditioning (AC). However, with the right approach, you can stay cool without worrying about high electricity bills or unnecessary energy waste.

In this article, we’ll share practical tips on energy efficient air conditioning, so you can stay comfortable while saving money and reducing your environmental impact. Keep reading for the full details!

How to Save AC Electricity

Did you know that air conditioning (AC) is the biggest driver of rising electricity demand worldwide? Between 2018 and 2050, AC usage is expected to account for 37% of the world’s total electricity consumption.

The amount of electricity an AC unit requires depends on its type and size. On average, central air conditioners use 3,000–3,500 watts per hour, portable air conditioners consume around 2,900–4,100 watts, and window air conditioners require approximately 900–1,440 watts.

With such high energy consumption, choosing an energy-efficient air conditioner is a smart way to save. Wasting electricity not only raises your utility bills but also harms the environment.

According to Our World in Data, air conditioning is responsible for about 3% of global greenhouse gas emissions. That’s why knowing how to use your AC efficiently is crucial. Below, we’ll explore the best ways to reduce energy consumption without sacrificing comfort.

1. Using an AC with Low Horsepower (PK)

One way to save electricity when using air conditioning is to choose a unit with lower horsepower (PK).

The higher the PK, the more powerful the AC is at cooling a room—but it also consumes more electricity.

In Indonesia, AC units come in various PK options, ranging from ½, ¾, 1, up to 2.5. To choose one, you must consider the room needs. For smaller spaces, such as a 10 m² bedroom, an AC with ½ PK is usually sufficient.

2. Set the Temperature Efficiently

Another way to save electricity is by adjusting the AC temperature wisely. To do this, consider the weather and the surrounding environment. The ideal AC temperature typically ranges between 24–28°C.

If the room already feels cool, try raising the temperature slightly instead of keeping it too low. Lower temperatures increase electricity consumption and can put extra strain on the compressor, potentially shortening its lifespan.

3. Using an Inverter AC 

Nowadays, you can find many energy-saving electronic devices, including inverter ACs. This type of air conditioner is considered more efficient than conventional models.

Inverter ACs provide effective cooling without consuming excessive electricity. They can adjust power usage based on the desired temperature, preventing the unit from constantly running at full capacity. This helps reduce energy consumption and improve efficiency.

4. Keep the Room Closed

Another way to save AC electricity is to avoid frequently opening and closing the room. When the AC is on, it’s important to keep doors and windows closed.

If they are left open, hot air from outside can enter while cool air escapes, making it harder for the AC to maintain the desired temperature.

As a result, the AC has to work harder, consuming more electricity and leading to unnecessary energy waste.

5. Activate Energy-Saving Mode

Many modern AC units now come with an energy-saving mode that helps reduce electricity consumption. This feature allows you to automatically adjust the temperature, fan speed, and other settings for optimal efficiency.

By using energy-saving mode, your AC can operate effectively without unnecessary energy waste. When purchasing an AC, be sure to understand its features, including energy-saving mode, to maximize efficiency and get the most out of your unit.

6. Wait Before Turning the AC Back On

Frequently turning the AC on and off can lead to unnecessary electricity waste. Keep in mind that the AC takes some time to fully stop operating after being turned off.

To avoid overworking the system, wait about three minutes before turning it back on. This allows the AC to reset properly and restart efficiently, preventing excessive energy consumption.

7. Activate the Timer

Running the AC all day, especially at low temperatures, can significantly increase your electricity bill. To prevent this, use the timer feature to automatically turn the AC on and off at specific times. This helps you manage energy consumption more efficiently.

8. Keep the Room Clean

Air conditioners don’t just cool the room—they also filter the air. That’s why maintaining a clean room is essential. If the room is dusty, the AC has to work harder to filter the air, leading to higher electricity consumption.

9. Clean the AC Regularly

In addition to keeping the room clean, it’s important to maintain the AC itself to ensure optimal cooling performance. A clean AC maintains a smooth airflow, allowing the system to cool the room efficiently without excessive electricity consumption.

10. Turn Off the AC When Not in Use

When leaving a room or house for an extended period, be sure to turn off the AC. Keeping the AC on in an empty room wastes electricity and increases energy costs unnecessarily.

11. Turning on Blower

For more effective cooling, try using a blower instead of lowering the AC temperature. A blower helps circulate air, similar to a fan, allowing cool air to spread evenly without making the AC work harder. This simple step can reduce energy consumption while keeping your space comfortable.

These are some practical tips to help save AC electricity. As mentioned earlier, excessive AC use can strain both your budget and the environment. By following these strategies, you can stay cool and comfortable while using energy more efficiently.

That’s why using an energy efficient air conditioning is a wise option—not only to keep electricity bills in check but also to reduce carbon emissions and protect the environment. Besides using AC more efficiently, you can also contribute to environmental preservation through various actions, such as joining Indonesia Asri.

This environmental campaign by Chandra Asri Group encourages real actions to care for the planet while promoting a sustainable lifestyle. Through initiatives like #SiPalingSustainable, you can take small but impactful steps—such as sorting waste and using public transportation—to help create a cleaner, greener environment.
