A Common Habit 9 Out of 10 People Make When Using Air Conditioners: Wastes Energy and Harms Your Health

Below are common mistakes most people make when using air conditioners, along with practical solutions to save electricity and protect your health.

During hot summer days, the air conditioner has become an essential “companion” in every household. However, not everyone knows how to use it effectively. Many seemingly harmless habits can lead to soaring electricity bills and even negatively impact your health. Here are the most frequent air conditioner misuse habits and how to fix them.


1. Setting the Temperature Too Low

One of the most common mistakes is setting the air conditioner to a very low temperature—often below 20°C—hoping to cool the room faster. This not only overloads the system and consumes excessive energy but can also cause thermal shock when moving from the hot outdoors into a cold room. The ideal temperature range is 25–27°C, which saves energy and is comfortable for the body.


2. Turning the AC On and Off Frequently

Some people turn the air conditioner off once the room is cool, then back on when it warms up. This forces the compressor to restart repeatedly, using more electricity than keeping it running steadily. Instead, leave it on continuously in energy-saving mode to maintain a stable temperature efficiently.


3. Not Cleaning the AC Regularly

Dust buildup on the AC filter blocks airflow, making the unit work harder and use more electricity. Worse, accumulated dust and bacteria can lead to respiratory issues like sore throats or allergies. Clean the filter at least once every 1–2 months to maintain performance and air quality.


4. Sealing the Room Without Ventilation

To keep cool air inside, many people seal their rooms tight while running the AC. However, without regular ventilation, the air becomes stale and oxygen-deprived, causing fatigue and discomfort. Open a window or use a ventilation fan for 15–20 minutes daily to refresh the air and keep the environment healthier.

5. Using the AC All Night

Nighttime temperatures are lower, yet many still run the AC continuously at low settings. This not only wastes electricity but also dries out the skin, nasal passages, and may cause colds. Set a timer or raise the temperature to around 27–28°C while sleeping to save power and stay healthy.


6. Improper AC Placement

The placement of your AC unit affects both efficiency and power consumption. Installing it where it’s exposed to direct sunlight or near heat-generating appliances (like TVs or stoves) forces it to work harder. Choose a shaded, well-ventilated area for installation to ensure even cooling and reduced energy use.


7. Not Using Fans to Help Circulate Air

Some think using a fan with the AC is unnecessary, but fans help circulate cool air more evenly and reduce the load on the air conditioner. Use a ceiling or standing fan on low speed alongside the AC to enhance comfort while saving electricity.


8. Ignoring Energy-Saving Modes

Most modern air conditioners come with an Eco Mode or Inverter Technology, but many people forget to activate these features, leading to wasted energy. Make use of energy-saving modes or choose an Inverter model to reduce power consumption while maintaining cooling efficiency.


9. Skipping Regular Maintenance

Besides filter cleaning, many users neglect full system maintenance. Problems like gas leaks, weak motors, or damaged parts make the unit inefficient and power-hungry. Get your AC professionally serviced every 6 months to keep it running smoothly.


10. Using the Wrong AC Size for Your Room

Choosing an AC with the wrong capacity for your room size is another common mistake. A unit that’s too small will run constantly to keep up, wasting energy and reducing its lifespan. Conversely, an oversized unit cools too fast and wastes power. Consult with experts to pick the right AC capacity for your space.


Smart AC Usage Solutions

To save electricity and protect your health, it’s essential to break these bad habits. Some specific tips include:

  • Maintain an optimal temperature (25–27°C)

  • Clean and maintain the unit regularly

  • Use energy-saving modes

  • Use fans to circulate air

  • Choose the right AC capacity for your needs

These small changes can significantly reduce your electricity bills and create a healthier living environment.

Using your air conditioner properly is not just about cutting energy costs—it directly affects your family's well-being. Recognizing and correcting these common mistakes allows you to enjoy a cool, comfortable space without worrying about high bills or health risks. Start today and become a smart AC user!
