5 Expert Tips For Using Your Air Conditioner In Extreme Heat

October 27, 2025

As temperatures in the Gold Coast hit 36°C today, your air conditioner becomes more than a comfort – it’s a necessity. But using it the wrong way during extreme heat can shorten its lifespan, increase your energy bill, and even affect your health. At DEEPCHILL, your trusted air conditioning Gold Coast specialists, we’ve put together 5 expert-backed tips to help you use your air conditioner in extreme heat efficiently and safely.

1. Set a safe temperature difference

When it’s scorching outside, it’s tempting to set the AC to 18°C for instant relief. But doing so can lead to thermal shock when moving between cool and hot environments, and it forces your unit to overwork.

Experts recommend keeping your indoor temperature no more than 6-8°C lower than the outdoor temperature.

For example, if it’s 36°C outside, set your air conditioner to around 28°C. You’ll stay cool without straining your system, or your body.

2. Use fans to improve air circulation

During extreme heat, your AC may struggle to push cool air evenly across the room. Using a ceiling or standing fan helps circulate the air better, allowing your air conditioner to work more efficiently.

This small trick can reduce energy consumption by up to 15%, extend your system’s lifespan, and make the space feel cooler without lowering the thermostat further.

At DEEPCHILL, we often recommend this setup to Gold Coast homeowners dealing with high humidity and large open spaces.

3. Take breaks from air-conditioned rooms

While it feels amazing to stay cool indoors all day, prolonged exposure to cold, dry air can cause dehydration, dry skin, or respiratory irritation. Step outside occasionally or let natural airflow in to balance humidity levels.

If you’re working from home, try switching off your AC for short intervals or use the “Eco” mode during cooler parts of the day. This keeps your body comfortable and your air conditioner in better condition.’

4. Cool down before entering an air-conditioned room

After being out in the 36°C Gold Coast sun, walking straight into a cold room can shock your body. Sudden temperature changes cause blood vessels to constrict, increasing the risk of dizziness or heat-related illness.

Before entering, rest in a shaded area for a few minutes and wipe away sweat. Once inside, avoid standing directly under cold airflow. Let your body gradually adapt to the indoor temperature for better comfort and safety.

5. Schedule regular cleaning and maintenance

A dusty or neglected unit can struggle to cool your home during extreme heat. Dirty filters and coils restrict airflow, making your system work harder and costing you more in electricity.

Book a professional air conditioner service in the Gold Coast every 3–6 months, especially before and during summer. Regular HydroClean and maintenance checks help prevent breakdowns and ensure your system operates at peak efficiency.

Final thoughts

With the Gold Coast now reaching 36°C, these simple adjustments can make a big difference in both comfort and energy savings.

By using your air conditioner in extreme heat the right way – alongside proper maintenance – you’ll protect your health, your equipment, and your electricity bill.
