As the scorching summer heat waves roll in, air conditioners have become an indispensable appliance in every household. However, not everyone knows how to use this equipment efficiently. Many seemingly harmless habits can cause a spike in electricity bills and have serious implications for your health. Here are some common mistakes that most people make when using air conditioning, along with solutions to save energy and protect your well-being.
1. Setting the temperature too low
One of the most common habits is to set the air conditioner temperature too low, often below 20 degrees Celsius, in the hope of quick cooling. However, this not only overworks the machine, consuming more electricity, but it can also cause heat shock when transitioning from the outdoors. The ideal temperature range is between 25-27 degrees Celsius, which is energy-efficient and provides a comfortable environment for your body.

2. Constantly turning the AC on and off
Some people have a habit of turning on the air conditioner, then turning it off once the room is cool, only to turn it back on when they feel hot again. This practice causes the compressor to restart multiple times, consuming more electricity than if it were left running continuously. Instead, opt for using the energy-saving mode, which helps maintain a stable temperature without excessive energy consumption.
3. Neglecting regular cleaning and maintenance
Air conditioner filters can get clogged with dust and dirt over time, obstructing airflow. This forces the machine to work harder to cool the room, resulting in higher electricity usage. Additionally, the buildup of dust and bacteria can lead to respiratory issues such as sore throat and allergies. It is essential to clean the filters at least once every one to two months to ensure optimal machine performance and air quality.
4. Keeping windows and doors closed without proper ventilation
To retain the cool air, people often close windows and doors when using the air conditioner. However, without proper ventilation, the indoor air can become stuffy and lacking in oxygen, causing fatigue and discomfort. Open windows or turn on exhaust fans for about 15-20 minutes daily to refresh the air and create a more pleasant living space.

5. Running the AC throughout the night
During the night, outdoor temperatures drop, but many people still keep their air conditioners running at low temperatures. This practice is not only wasteful but can also lead to dry skin, nose, and even a cold. Utilizing the timer function or increasing the temperature to 27-28 degrees Celsius while sleeping will help conserve energy and maintain your health.
6. Improper installation location
The location of your air conditioner greatly impacts its cooling efficiency and energy consumption. Some households install their AC in areas exposed to direct sunlight or near heat-generating appliances like TVs or ovens. This setup forces the machine to work harder to achieve the desired temperature. Opt for a well-ventilated area, shielded from direct sunlight, ensuring even distribution of cool air throughout the room.
7. Underutilizing fans
Contrary to popular belief, using fans in conjunction with air conditioning is beneficial. Fans help circulate air, dispersing the cool air more evenly and reducing the burden on the AC. Combining ceiling or standing fans at low speeds not only saves energy but also provides a more pleasant cooling experience.
8. Ignoring energy-saving modes
Most modern air conditioners are equipped with energy-saving modes (Eco Mode) or Inverter technology. However, many people overlook these features, resulting in unnecessary energy waste. By activating the energy-saving mode or choosing an Inverter model, you can reduce power consumption while maintaining effective cooling.
9. Neglecting regular maintenance
In addition to cleaning the filters, comprehensive maintenance of the entire air conditioning system is often overlooked. Issues like gas leaks, weak motors, or faulty components can hinder the machine’s efficiency and lead to higher electricity bills. Regular maintenance checks every six months are recommended to ensure optimal performance and longevity.
10. Choosing the wrong AC capacity for your space
Selecting an air conditioner with an inappropriate capacity for your room size is a common mistake. An undersized AC will struggle to cool the space, running continuously and increasing electricity costs and reducing its lifespan. Conversely, an oversized unit will quickly lower the temperature but may result in wasted energy. Consult experts to choose an air conditioner that matches your space requirements.
