Energy Efficiency -Aircon

Living in Brisbane, you’re no stranger to the sweltering heat! Let’s dive into how adjusting your air conditioner’s temperature by just one degree can impact your electricity bill:

1. Ideal Temperature Settings:

• During summer cooling, set your air conditioner somewhere between 22 to 24 degrees Celsius.
• For winter heating, aim for around 18 to 20 degrees Celsius.
• These ranges ensure maximum energy efficiency from your unit.

2. Energy Consumption and Costs:

• The harder your air conditioner works, the more electricity it consumes.
• Lowering the cooling temperature and raising the heating temperature both contribute to higher energy usage.
• Ergon Energy estimates that every one degree cooler in summer adds approximately 10% to your air conditioner’s electricity consumption.
• Let’s break it down further:
