How to Reduce Air Conditioner Power Consumption? 8 Guaranteed and Effective Ways to Avoid High Electricity Bills

According to Saed News, as summer and hot days approach, everyone turns to air conditioners. However, concerns about air conditioner electricity consumption (even in fan mode) and the shock of high electricity bills can take away the pleasure of cool air.

For this reason, we all look for ways to reduce the power consumption of split air conditioners and other models, asking ourselves: How can we reduce air conditioner electricity usage? In this article, we will cover several key tips to lower air conditioner electricity usage. Stay with us until the end.

8 Effective Ways to Reduce Air Conditioner Electricity Consumption

Below are important tips to help you cut down on electricity usage without needing special power-saving devices (some of these tips are sourced from EnerCare).

1. Install the Air Conditioner in the Right Location

Choosing the right installation location is crucial. If the AC is not installed properly, it may not only face operational issues but also increase electricity consumption.

  • The indoor unit should ideally be positioned where cool air reaches family members directly.

  • Since hot air accumulates near the ceiling, the indoor unit should be installed lower to improve cooling efficiency.

  • The outdoor unit should be placed where air can flow freely behind it.

Additionally, the air-throw range of split air conditioners typically ranges from 5 to 10 meters, depending on capacity. Make sure to consider this for optimal cooling.

2. Check the Energy Label

One of the first steps to reducing AC power consumption is choosing an energy-efficient model.

  • Opt for inverter models or those with an energy rating of A or B.

  • Inverter technology adjusts the compressor speed based on cooling needs, reducing power usage.

  • Check the EER (Energy Efficiency Ratio) before buying. A unit with low amperage but poor cooling performance will consume more power as it struggles to cool the room.

For example, if you buy a 32,000 BTU AC with low cooling efficiency, it will work harder, increasing electricity usage.

3. Set the Right Temperature

Adjusting the temperature to an optimal level prevents excess power consumption.

  • The ideal AC temperature is between 24°C and 26°C.

  • Setting it too low forces the compressor to work continuously, increasing power usage.

  • At the correct temperature, the AC consumes less power, even if it is running constantly.

4. Choose the Right AC Capacity

Selecting an AC unit with the correct cooling capacity can reduce electricity consumption by up to 20%.

  • For top-floor apartments (exposed to direct sunlight), you need:

700-800 BTU per square meter for residential use.

900-1200 BTU per square meter for offices/commercial spaces.

  • For mid-floor apartments (better insulated):

400-500 BTU per square meter for homes.

700-1000 BTU per square meter for offices/commercial use.

If your room is small, a portable AC may be a better choice.

5. Do Energy-Efficient Light Bulbs Help?

Yes! Using LED or energy-saving bulbs reduces heat in the room, which helps lower AC power consumption.

  • Traditional bulbs generate extra heat, forcing the AC to work harder.

  • Switching to energy-efficient bulbs reduces AC workload and power consumption.

6. Ensure the AC is in Good Condition

If your AC is faulty, it will consume more power to maintain the set temperature.

  • Annual servicing is essential to maintain efficiency.

  • If you notice issues, seek professional repair and maintenance services promptly.

7. Regular AC Servicing Reduces Power Usage

One of the best ways to save energy is to service your AC once a year.

  • Regular maintenance prevents problems.

  • A well-maintained AC runs efficiently, reducing electricity bills.

8. Use a Smart Thermostat

A programmable thermostat helps control power consumption by automatically adjusting AC settings.

  • You can set specific times for turning the AC on/off.

  • It ensures the AC does not run when not needed, saving electricity.

What Is an Air Conditioner Power Saver Device?

A power saver device stores electricity while the compressor is off, helping to reduce power consumption. It works by:

  • Storing power when the AC compressor stops due to temperature saturation.

  • Releasing stored power efficiently when needed, cutting down on overall consumption.

How Much Electricity Does an AC Use in Fan Mode?

When the AC is set to fan mode, power consumption drops significantly.

  • If the thermostat is functioning well, the AC automatically switches to fan mode once the desired temperature is reached.

  • Using fan mode when the weather is not extremely hot is a great way to save electricity while keeping the air circulating.

Conclusion

By following these eight key strategies, you can significantly reduce your air conditioner’s power consumption, lower your electricity bills, and still enjoy cool air without stress.
