Did you know that setting the right temperature on your air conditioner is not only essential for your comfort and health, but can greatly reduce your electricity costs? Whether you’re cooling in summer or heating in winter, a few simple steps help you achieve optimal efficiency — perfect climate control for your home or business, without excessive energy bills.
The best way to ensure maximum energy efficiency is to set your air conditioner temperature correctly and follow the recommended tips below for the best performance all year round.
Tips to keep your house cool in summer
- Run your aircon economically at 22–24°C for comfort, and 25–27°C for maximum energy savings.
- Keep windows closed and block out UV rays by closing curtains or blinds.
- Use a fan alongside your aircon to help recirculate the cool air. Ceiling fans have a winter (up airflow) and summer (down airflow) mode switch.
- Ceiling and wall insulation helps keep the cool air contained in your home.
Tips to keep your house warm in winter
- Run your aircon at 15.6–19.4°C for adults, and 20–22.2°C for babies, for heating in the cooler months.
- Make sure your home is sealed properly — poorly sealed areas let cool draughts in and warm air out.
- Close drapes or blinds to prevent warm air escaping through window glass.
- Set your ceiling fan to its winter setting to circulate the warm air.
The benefits of running your air conditioner at the right temperature in winter
- Health — the wrong temperature can cause humidity and affect air quality by encouraging the growth of fungus and mould, which can cause breathing difficulties, especially for asthma sufferers.
- Cost — it’s tempting to set your aircon to 28°C when it’s cold outside, but this makes the unit work overtime and increases your energy use. Run it at the recommended temperature instead.
- Comfort — being too hot or too cold can leave you feeling exhausted or unwell. The right temperature protects your comfort and wellbeing.
