What is Dry Mode in Your AC System?

Author: Lance Wiggers

Most Australians rely on air conditioning systems to stay cool during scorching summers and warm during chilly winters. But did you know that air conditioners can also regulate humidity? One useful feature is dry mode, which removes excess moisture from the air to create a more comfortable and healthier indoor environment.

In this guide, we’ll explain what dry mode in AC is, explore the difference between cool and dry mode in AC, and share tips for using it effectively, including the best temperature for dry mode.

What is Dry Mode in AC

Dry Mode: Your AC’s Solution to Humidity

Dry mode is specifically designed to lower indoor humidity levels. This feature is particularly helpful in humid weather, where the air feels sticky, but temperatures aren’t high enough to warrant full cooling.

Unlike cool mode, which lowers the temperature, dry mode focuses on moisture removal. This eliminates the damp, clammy feeling common in Australia’s humid coastal and tropical regions. Many Australians with dry mode aircon rely on this feature to stay comfortable during the wet season.

Identifying Dry Mode on Air Conditioner

 

Recognising Dry Mode on Your Air Conditioner

Not all air conditioners are equipped with dry mode, but it is a common feature in many modern split systems and ducted air conditioners used in Australian homes. To identify whether your unit has this function, check your remote control:

  • A water droplet symbol or the word “Dry” typically indicates dry mode.
  • A snowflake symbol represents cool mode.
  • A fan symbol usually refers to fan mode.

If you’re upgrading your air conditioning system, choosing one with dry mode can make a significant difference in managing humidity and enhancing comfort.

How Dry Mode Works to Improve Your Comfort?

Dry mode functions much like a dehumidifier, focusing on removing moisture from the air. Here’s how it operates:

  • Humid Air Intake: The AC pulls in moist air from the room.
  • Moisture Condensation: The evaporator coil condenses water vapour and drains it away through the system’s pipes.
  • Releasing Drier Air: The AC releases drier air back into the room, reducing humidity levels.

This process doesn’t drastically cool the air but leaves the room feeling fresher and more comfortable.

Difference Between Cool and Dry Mode in AC

 

Understanding the Difference Between Cool and Dry Mode in AC

The difference between cool and dry modes in AC lies in their core functions:

  • Cool Mode: Actively lowers the temperature by removing heat from the air, making it ideal for Australia’s sweltering summers.
  • Dry Mode: Focuses on removing moisture from the air without significantly altering the temperature, making it perfect for humid but mild days.

When comparing dry vs cool mode, consider the conditions:

  • Choose cool mode for days that are both hot and humid, as it addresses heat and moisture together.
  • Opt for dry mode on damp or rainy days when humidity is high but the temperature is comfortable.

 

The Best Temperature for Dry Mode

For the best temperature for dry mode, set your air conditioner to 24°C. This temperature effectively reduces indoor moisture without making the room feel too cold. Dry mode controls humidity effectively, but it doesn’t handle extreme cooling. Switch to cool mode on particularly hot days.

Why Dry Mode is Ideal for Humid Conditions?

Dry mode offers multiple benefits, making it a practical choice for many Australian households:

  • Energy Efficiency: Dry mode uses less energy than cool mode, as it doesn’t require the compressor to work as intensively. This can lead to noticeable savings on electricity bills.
  • Healthier Indoor Air: By maintaining humidity levels between 35% and 60%, dry mode helps prevent the growth of mould, dust mites, and bacteria, which can trigger allergies or respiratory issues.

  • Balanced Comfort: It provides relief from humidity without overcooling, ensuring a comfortable indoor environment.

To avoid excessively dry air, limit your use of dry mode to 1–2 hours at a time.

When to Use Dry Mode in Your AC?

Dry mode works best in specific situations, such as:

  • Humid, Sticky Days: Especially during the wet season.
  • Rainy Weather: To combat the increased indoor moisture caused by damp outdoor conditions.
  • Energy-Conscious Cooling: When you want to manage humidity without overcooling or running the AC on full power.

On the other hand, cool mode is better suited for:

  • Hot, Dry Days: When significant cooling is needed.
  • High Heat and Humidity: To simultaneously address temperature and moisture.

Understanding the difference between cool and dry modes in AC helps you choose the right setting for different weather conditions while maximising efficiency.

Using Dry Mode Beyond Summer

 

Using Dry Mode Beyond Summer

Dry mode can also be useful in cooler seasons, especially during rainy winter days when indoor humidity levels rise. However, if the room becomes too cold, switch to heat mode for a more comfortable temperature. For improved air circulation without altering temperature or humidity, consider using fan mode.

Additional Modes for Custom Comfort

Modern air conditioners offer several modes to meet varying needs:

  • Cool Mode: Actively cools the room, perfect for Australia’s hot summers.
  • Heat Mode: Provides warmth during winter.
  • Fan Mode: Enhances air circulation without changing temperature or humidity.
  • Auto Mode: Adjusts temperature and fan speed automatically based on room conditions, though it may use more energy.
