Does dry mode save electricity?

Exploring how using the dry mode of an AC can save electricity since the fan operates at a lower speed and the compressor is only running in spurts.


If you have recently bought an air conditioner you will notice that it has a few modes such as dry, cool, sleep, and fan mode. Each of these modes work differently depending on what you need your air conditioner to do to manipulate temperatures.

Looking at the dry mode in particular, this mode can take on a dehumidification function and reduce some of the humid air in the room or environment. Dry mode works in a particular way, but it also helps you save on electricity bills.

Dry mode in air conditioners

The dry mode function is a relatively new mode in air conditioners and can be particularly useful in places where the climate is particularly wet, but still has high humidity levels. The dry mode performs a similar function as a dehumidifier, though not completely the same.

So you may be wondering, since air conditioners are large consumers of energy, can this mode somehow save you money on electricity?

Fortunately, with some of the latest technological advancements in new, modern air conditioners, various modes such as the dry mode can help reduce energy consumption of air conditioners.

Does dry mode save electricity?

The answer is yes, it can be an energy-saving option as the fan and the compressor are both running slower and for shorter durations.

The primary function of the dry mode function is to reduce the humidity in an environment, while also bringing its temperature down.

This setting will come in handy in wet, rainy weather and moist environments close to water such as the sea. Dry mode removes the discomfort caused by humidity.

As mentioned above, with this setting the fan will run at a lower speed and the compressor will run in gushes over large cycles, helping lower the humidity levels in a space.

It is important to note, though, that in dry mode you do not get as much cooling from the unit.

Is the dry mode function and a dehumidifier similar?

The dry modes of an air conditioner and a dehumidifier are similar but only to a certain extent. They share similarities in their benefits as well as in how their drainage systems work.

Both improve the quality of the air in a room, provide proper ventilation in an indoor space, remove some allergens accumulated in the air, and resolve health issues caused by excessive air moisture.

They also both store and release moisture after extracting it from the air in a room or space.

What are the differences between dehumidifiers and the dry mode function?

A dehumidifier and the dry mode of an air conditioner deal with moisture differently. Dry mode extracts moisture from the condensate towards a drainage tube, while dehumidifiers store the moisture in a moisture tank inside it that needs to be emptied regularly.

Dry mode


Transports moisture through drainage pipes Moisture is contained in its tank
Removes moisture via coils and releases it after cooling air Removes moisture via hot or cool coils to be released
Releases cool air into the room Does not control the temperature of a room

How long should dry mode be used?

Dry mode should not be used for prolonged periods of time as this may lead to discomfort or other issues if the air is completely stripped of moisture. You should use dry mode in moderation as it can lead to excessive energy consumption if it is always on.

The recommended run-time for dry mode is around two to three hours, anything beyond this may lead to excessive dryness in the air that can cause other issues such as dry skin and other forms of irritation from an environment that is too dry.

Final thoughts

The advancement of technology when it comes to air conditioners has allowed air conditioners to better cater to a range of different climate requirements.

This helps adjust the air and temperatures accordingly without merely cooling and heating a space. Different modes offer various functions.

When it comes to the dry mode in an air conditioner, your unit will remove some humidity in the air, especially in wetter climates and locations. Excessive humidity can be an issue and dry mode offers a solution for this. Additionally, it saves electricity.
