When and How Should You Use Your Air Conditioner’s Dry Mode?

by | Jul 22, 2022 | Air Conditioning, Air Conditioning Service


Did you know that your air-conditioning system can also help maintain a comfortable indoor humidity level? With your air conditioning unit’s dry mode, you are in control of the moisture and humidity of your living space.

Not only can air conditioners cool and heat your home, but they can also regulate the temperature and humidity in your living space. In addition to cooling and heating, modern air conditioners can dehumidify, ventilate and even purify the air. There are multiple modes and features on your air conditioner’s remote control that you may have never used. One such underrated feature is the dry mode in your air conditioner.

What is Dry Mode?

The dry mode or “dehumidification” is a feature that can be found on several ducted and split-type air conditioning units that can reduce humidity levels in a room. It is intended for days when the weather is humid but not too hot or too cold. It’s for those days when the weather has a tropical feel, but it’s just a little too cool to use cooling mode.

Do all Types of Air Conditioning Units Have Dry Mode?

Although the dry mode is a common feature on many ducted and split system air conditioning systems, not all models have the function. You can check whether your unit comes with a dry mode through the remote control. Look for the button with the word “dry” on it or a water droplet symbol. The cool mode is usually signified with a snowflake symbol.

How Does Dry Mode Work?

When the air conditioner is in dry mode, it sucks out moisture from the air. This process is similar to that of a dehumidifier, lowering humidity and capturing moisture in the air, thus releasing fresh and breezy air. 

The humid or moist air from the room is sucked into the air conditioning unit, the air is then condensed in the evaporator, removing excess moisture, and the dry air is released back into the room to help lower the overall moisture level.

Air conditioning modes – what do they mean?

Dry Mode vs Cool Mode vs Fan Mode

As you probably know, the cool mode cools the air. It is widely considered the default mode of most air conditioners and is the mode that you’re probably most familiar with. This mode is heavily reliant on the air conditioning unit’s compressor, the energy output is dependent upon the temperature of your air conditioner as well as fan settings.

Conversely, the dry mode of an air conditioner is not intended to introduce cold air into the room. It removes excess moisture. An additional benefit of the dry mode is it is more energy-efficient than the cool mode.

When the air quality is ideal and you need air circulation in your room, turn on the fan mode. Unlike dry mode, the fan does not suck moisture from the air. It still maintains a pleasant indoor environment.

Other Useful modes of your Air Conditioning Unit

Heat Mode / Reverse Cycle

It is best used during the winter or those cold days to maintain a comfortable temperature. 

The range of heating options can be bewildering. In Australia, gas ducted heating and reverse cycle heating are two of the most popular choices. The choice is actually much clearer than you might think. In fact, according to the Department of Climate Change, energy, the Environment, and Water, Reverse-cycle air conditioning is 300–600% efficient.  If you want to save money and reduce your utility bills, refrigerated air conditioning systems with reverse cycle mode are the best choice.

Auto Mode

Auto mode sets the temperature and fan speed according to what temperature is detected by the sensor. The set point is the temperature the thermostat is set at. However, the auto mode can be a little less energy efficient than other modes.


Dry Mode Air Conditioning Benefits

  • The dehumidification that the dry mode offers can improve and optimise the humidity level of your home, which helps your family breathe easier. It can reduce common allergy triggers that thrive in an excessively humid environment including dust mites, moulds, and mildew
  • Dehumidification eliminates odours associated with mould, dampness, or mildew in your home.
  • Living in a high humidity climate can also cause problems for your clothing, furniture, bed linen, towels, and curtains. Over time, excessive moisture can develop mould. This can also cause minor or serious damage to your electronic devices and home appliances. The dehumidification benefit of your air conditioner’s dry mode is proven to protect your belongings.
  • When your air conditioner is on dry mode, the unit’s compressor runs at a slower pace, meaning it will use less energy and eventually save you money on your monthly bill.
