What is Eco Mode on a Mini Split?

Eco mode on a mini split is an energy-saving feature designed to reduce energy consumption while maintaining a comfortable temperature. When eco mode is activated, the mini split operates at a lower capacity and makes intelligent adjustments to save energy. This mode is particularly useful for night-time cooling or when you are away from home, helping to preserve comfort while saving money on electricity bills.

Enabling Eco Mode on a Mini Split

To enable eco mode on a mini split, locate the green leaf icon on your remote controller, point it at the AC, and press the button. The specific temperature settings for eco mode can vary, but in general, the eco temperature is the setting on your thermostat when nobody is home. In winter, it is best between 18-21°C, and in summer, 24-32°C.

Adjusting Eco Mode Temperature Settings

The eco mode temperature settings can be adjusted to suit your specific needs and preferences. Most mini split units will have a dedicated button or menu option to access the eco mode settings. Here’s a step-by-step guide on how to adjust the eco mode temperature:

  1. Locate the eco mode button or menu on your mini split remote control or control panel.
  2. Press the eco mode button or navigate to the eco mode menu.
  3. Use the up and down arrows to adjust the eco mode temperature setting.
  4. Once you’ve set the desired eco mode temperature, press the “OK” or “Enter” button to save the setting.

It’s important to note that the eco mode temperature range may vary depending on the manufacturer and model of your mini split unit. Refer to your owner’s manual for the specific temperature range and adjustment instructions.

Limitations of Eco Mode

It is important to note that if you live in an extremely hot, cold, or humid area, the ECO mode might struggle to lower the temperature or humidity on short notice. In such situations, it is best to disable the mode temporarily and activate it when the room temperature nears your desired level.

Factors Affecting Eco Mode Performance

Several factors can affect the performance of the eco mode on a mini split, including:

  1. Outdoor Temperature and Humidity: Extreme outdoor temperatures and high humidity levels can challenge the eco mode’s ability to maintain the desired indoor temperature and comfort level.
  2. Room Size and Insulation: Larger rooms or poorly insulated spaces may require more cooling capacity, which the eco mode may struggle to provide.
  3. Number of Occupants: The more people in the room, the more heat and humidity will be generated, potentially overwhelming the eco mode’s energy-saving adjustments.
  4. Appliance Usage: Running high-heat-producing appliances, such as ovens or stoves, can also impact the eco mode’s ability to maintain the desired temperature.

In these situations, it may be necessary to temporarily disable the eco mode and switch to a higher cooling capacity mode to ensure optimal comfort and temperature control.

Benefits of Eco Mode

In addition to energy savings, eco mode can also help reduce wear and tear on the unit’s compressor, potentially prolonging its lifespan and reducing the need for repairs.

Energy Savings

The primary benefit of eco mode is the potential for significant energy savings. By operating the mini split at a lower capacity and making intelligent adjustments, the unit can consume less electricity while still maintaining a comfortable temperature. This can lead to lower monthly energy bills and a more environmentally friendly cooling solution.

Compressor Lifespan

The reduced workload on the compressor during eco mode operation can also help extend the lifespan of the unit. By not running the compressor at full capacity all the time, the wear and tear on the component is reduced, potentially leading to fewer repairs and a longer overall lifespan for the mini split system.

Noise Reduction

Another benefit of eco mode is the reduced noise level. With the compressor running at a lower capacity, the overall sound output of the mini split unit is typically lower, creating a more peaceful and comfortable indoor environment.

Balancing Energy Savings and Comfort

However, it is important to balance energy savings with user comfort, as reducing the compressor speed can limit the unit’s cooling capacity and may cause the room to feel hotter than when running on auto mode.

Adjusting Eco Mode Settings

To find the right balance between energy savings and comfort, you may need to experiment with the eco mode settings on your mini split. Try adjusting the eco mode temperature setting in small increments to find the sweet spot where you can still achieve significant energy savings without sacrificing too much comfort.

Monitoring Eco Mode Performance

It’s also important to monitor the performance of the eco mode and how it affects the indoor temperature and humidity levels. If you find that the eco mode is not maintaining the desired comfort level, you may need to temporarily disable the mode or adjust the settings further.


In summary, eco mode on a mini split is a valuable feature for those looking to save energy and reduce electricity bills. By operating at a lower capacity and making intelligent adjustments, this mode can help maintain a comfortable temperature while reducing energy consumption. However, it is important to balance energy savings with user comfort and to consider the specific needs of your home and climate when using eco mode.
