Does Aircon in Fan Mode Increase Power Consumption?

Many people wonder whether using an air conditioner in fan mode consumes more power than using it in cooling mode. In this blog post, we will explore this question in detail and provide you with all the information you need to understand the power consumption of air conditioners in fan mode.

Understanding Air Conditioner Fan Mode

Air conditioners have different operating modes, including cooling mode and fan mode. In cooling mode, the air conditioner cools the air by removing heat from the room. The compressor and the fan work together to achieve this cooling effect. On the other hand, fan mode operates solely by circulating the existing air in the room without cooling it.

Power Consumption in Cooling Mode

When an air conditioner is running in cooling mode, it consumes a significant amount of power. The compressor works hard to compress and expand refrigerant gases, enabling the cooling process. Additionally, the fan needs to circulate a large volume of air to distribute the cool air throughout the room. Consequently, using an air conditioner in cooling mode typically leads to higher power consumption compared to fan mode.

Power Consumption in Fan Mode

When you switch your air conditioner to fan mode, the compressor shuts off, and only the fan operates. This change in operation significantly reduces power consumption. The fan in fan mode requires less power to operate as it only needs to circulate the air without any cooling functionality. Therefore, air conditioners in fan mode consume significantly less power compared to cooling mode.

Comparison of Power Consumption

It is essential to understand that power consumption varies depending on the specific model and capacity of the air conditioner. However, on average, air conditioners in fan mode consume only a fraction of the power used in cooling mode. Some studies suggest that when an air conditioner is in fan mode, it can consume up to 90% less power than in cooling mode.

Benefits of Using Aircon in Fan Mode

Using an air conditioner in fan mode offers several benefits:

  • Energy savings: As discussed, fan mode consumes significantly less power, leading to lower energy bills.
  • Circulates air: The fan continues to circulate the air in the room, creating a comfortable environment without cooling it.
  • Reduced noise: Fan mode is generally quieter compared to cooling mode, as the compressor is not operating.
  • Ventilation: By running the air conditioner in fan mode, you can improve ventilation by bringing in fresh air from the outside.


Does using aircon in fan mode save money?

Yes, using an air conditioner in fan mode can save money as it consumes significantly less power compared to cooling mode. By opting for fan mode instead of cooling mode, you can reduce energy consumption and lower your electricity bills.

In conclusion, running your air conditioner in fan mode consumes considerably less power compared to cooling mode. This energy-saving option not only reduces power consumption but also provides other benefits such as improved ventilation and reduced noise levels. So the next time you don't need the cooling function but want to circulate the air in the room, using the aircon in fan mode is a wise choice.
