When the heat starts to ease but the air still feels a little warm in the afternoon, many homeowners ask the same thing: What temperature to set air conditioner in fall? DEEPCHILL, your reliable air conditioning Gold Coast service will answer!
Recommended temperature to set for autumn
Autumn brings milder weather. The intense summer heat fades, humidity drops and nights become noticeably cooler. That change means your air conditioning Gold Coast does not need to work as hard as it did in January.
The recommended temperature range for autumn is 24°C to 26°C during the day.
Here’s why:
- It keeps your home comfortable without overcooling
- It reduces energy consumption
- It prevents the air from becoming too dry
- It protects your system from unnecessary strain
If the outdoor temperature is below 24°C, you may not even need cooling. Always check the outside temperature first before turning the unit on.

Full guide to set for day and night
During autumn days, set your AC between 24°C and 26°C on Cool mode.
Avoid using Dry mode in fall. Autumn air on the Gold Coast is already less humid than summer. Dry mode removes extra moisture, which can make your indoor air feel too dry and uncomfortable. Stick to Cool mode and adjust the fan speed as needed.
At night, temperatures often drop to around 20–22°C or even lower. In many cases, you can:
- Turn off the air conditioner completely
- Open windows for natural airflow
- Use a ceiling fan for gentle circulation
If you still prefer using the AC, raise the temperature to 26°C or higher or use the timer function so the unit switches off automatically after you fall asleep. This saves energy and keeps the room from getting too cold overnight.ture to set for day and night
