Autumn can be confusing. One minute it feels warm and sticky, the next it turns cool and breezy. So how to use air conditioning in autumn to stay comfortable and save energy without overdoing it? With the right settings and support from DEEPCHILL, your trusted air conditioning Gold Coast service, it’s easier than you think. Here are practical ways to adjust your air conditioning habits during autumn.
- Set the right temperature during the day
In autumn, you don’t need super low temperatures to use air conditioning.
- Set your AC between 26–28°C during warm daytime hours
- Keep the indoor and outdoor temperature difference within 5–7°C
- Avoid overcooling just out of habit
This prevents thermal shock, reduces energy use and keeps your home naturally comfortable.
- Adjust settings at night
Autumn nights on the Gold Coast are usually cooler.
- Increase the temperature before bedtime
- Use Sleep mode if available
- Set a timer to turn off the unit after a few hours
- On cooler nights, switch to Fan mode or turn the AC off completely
Sometimes, opening windows for fresh air is all you need.
- Use Dry mode only when necessary
Autumn can still bring humid days, but not every day needs full cooling.
- Use Dry mode on damp, humid days to reduce moisture
- Switch back to Cool mode when temperatures are high
- Avoid running Cool mode all day if humidity is the main issue
Dry mode uses less energy and helps prevent that sticky indoor feeling.

- Avoid frequent on-off switching
Turning your air conditioner on and off repeatedly actually wastes more electricity.
- Let the system run steadily when cooling is needed
- Use a moderate setting instead of blasting cold air
- Plan usage based on actual weather, not routine
Stable operation keeps your system efficient and extends its lifespan.
- Keep your unit clean and maintained
Seasonal changes are the perfect time to check your system.
- Clean filters every 2–4 weeks
- Check for dust, mold or unusual smells
- Ensure outdoor units are clear and ventilated
- Schedule professional servicing if needed
A clean system cools better, uses less energy and improves indoor air quality.
- Improve natural ventilation
You don’t always need mechanical cooling.
- Open windows during cool mornings or evenings
- Use ceiling fans for airflow
- Let fresh air circulate daily
Simple habits like these reduce dependence on use air conditioning and lower your energy bill.
