Can You Use A Dehumidifier And An Aircon At The Same Time?

March 31, 2026

Gold Coast autumn is famous for high humidity. When the air feels thick and “sticky”, many homeowners wonder: Can I use a dehumidifier and an aircon at the same time? The short answer is yes. In fact, combining these two devices is one of the most effective ways to manage the local climate. At DEEPCHILL, with over 40 years of experience in air conditioning Gold Coast, we have seen how this duo can transform indoor comfort.

Why you should use a dehumidifier with your aircon

While your air conditioner does remove some moisture, its primary job is to lower the temperature. Consequently, when the humidity is extremely high, your aircon might struggle to keep up. Here is why you should use a dehumidifier alongside your cooling system:

  • Increased comfort: Dry air feels cooler than damp air. By removing moisture, you feel refreshed even at higher thermostat settings.
  • Energy efficiency: When you use a dehumidifier, your AC doesn’t have to work as hard to “wring out” the air. This reduces the strain on your residential air conditioning Gold Coast systems.
  • Better health: Reducing humidity prevents the growth of mould and dust mites. This is vital for families with allergies or asthma.
  • Commercial protection: For businesses, using both helps protect sensitive electronics and stock in commercial air conditioning Gold Coast environments.

Can you use aircon as a dehumidifier?

Many modern units feature a “Dry Mode”. So, can you simply use your aircon as a dehumidifier?

Technically, yes. However, an air conditioner is not a dedicated moisture-removal machine. In “Dry Mode”, the fan runs slower to allow more condensation to form on the coils. While effective for light humidity, it may not be enough for a rainy Queensland week.
