An air conditioner is a true lifesaver, particularly in Australia where we encounter scorching summer days and hot, humid nights. It provides a sanctuary of coolness and comfort that’s essential in homes and businesses alike. It’s no surprise that the majority of Queensland households have at least one air conditioning unit for indoor comfort and climate control. Air conditioners don’t just control temperature — they also help filter out dust, allergens and pollutants for cleaner, healthier indoor air.
Have you ever wondered what dry mode on your air conditioner is, and when it’s best to use it? This feature can be an efficient way to reduce indoor humidity and make your living space more comfortable, particularly in the middle of summer. It’s especially beneficial in areas prone to high humidity and excess moisture, where dry mode lets your AC function as a dehumidifier.
How dehumidifying works
A dehumidifier is a device designed to reduce and maintain the humidity level in the air. They’re commonly used to prevent the growth of mould, mildew and dust mites, improve comfort, and protect property from moisture-related damage. If your AC has a dry mode, you can use it for the same purpose.
The process is quite simple. When you set the AC to dry mode, it draws in humid air from the space. That air passes over a cold coil, where moisture condenses into water droplets that are drained away through a hose. The air expelled back into the room is drier as a result.
Do all air conditioners come with dry mode?
Not all air conditioning systems have a dry mode or dehumidification function, but you’ll find that newer, more modern systems do. Modern split-system and ducted air conditioners are designed to offer multiple modes — including cooling, heating and dehumidifying — as do some portable and window units. If you’re unsure whether your air conditioner has a dry mode, refer to the user manual or check the control panel for an option labelled ‘dry’ or ‘dehumidify’.
How to effectively use dry mode on your air conditioner
If you’ve established that your AC has a dry mode, using it is straightforward. Refer to your owner’s manual for detailed instructions; the basic steps are as follows:
- Turn on the air conditioner and set it to dry (or dehumidify) mode — this reduces humidity rather than cooling the air.
- In dry mode the air conditioner may not lower the temperature significantly, so set the temperature to your preference. Remember, the goal is to reduce humidity, not cool the space.
- A slower fan speed is often recommended in dry mode to let the unit remove moisture effectively, so adjust the fan speed as required.
- Close doors and windows to prevent outside humidity from entering and maximise the effectiveness of dry mode.
- Dry mode collects moisture as condensation, so proper drainage is necessary to avoid water buildup and potential damage — check that your AC’s drainage system is working properly.
- Use a hygrometer to ensure indoor humidity stays around 30–50%, and make adjustments if necessary based on the readings.
Benefits of using dry mode as a dehumidifier
Using the dry mode feature can offer a more comfortable and healthier indoor environment when humid conditions are at their peak — with the added benefit of savings on your energy costs.
- Dehumidification helps eliminate odours that can be present in damp, mouldy spaces.
- Your property and belongings are protected from excess moisture, which can otherwise lead to mould on furniture, curtains and clothing, and rust or corrosion on appliances.
- Indoor air stays at optimum humidity levels, helping everyone breathe easier — a real benefit for allergy sufferers.
- Comfort improves noticeably: high humidity leaves us feeling lethargic, sweaty and clammy, which affects overall wellbeing.
