With energy prices on the rise across Australia, many households are looking for simple ways to cut down on their electricity bills without sacrificing comfort. If your air conditioner is one of the biggest contributors to your energy usage, you are not alone. In fact, cooling and heating are among the highest energy-consuming appliances in Australian homes.
The good news is that by adjusting your air conditioner settings, performing regular air conditioning maintenance, and understanding how your system works, you can enjoy cool or warm air without the cost blowout. This guide will show you how to maximise energy efficiency and lower your bills by making a few smart changes.
Why Air Conditioner Settings Matter
Your air conditioning system does not need to work harder than it should. One of the most common mistakes people make is setting their thermostat too low in summer or too high in winter. This forces the system to run longer and consume more power than necessary. The right settings help the system work within its optimal performance range, reducing wear and tear and improving energy efficiency. Choosing the right temperature setting, understanding zoning, and making use of built-in features like timers or eco-modes can significantly reduce your energy consumption without sacrificing comfort.
Ideal Air Conditioner Settings for Australian Homes
During summer, the recommended temperature for cooling mode is between 24 to 26 degrees Celsius. For every degree lower, your system uses around 5 to 10 percent more energy. So setting your air conditioner to 20 degrees instead of 25 could increase your electricity bill by up to 50 percent over time. In winter, the ideal heating mode setting is 18 to 20 degrees Celsius. Again, every extra degree costs you. A small tweak to your air conditioning settings can make a noticeable difference across the season.
Best Practices for Air Conditioner Efficiency
Getting the most out of your air conditioning services means combining the right settings with some smart habits. Below are essential steps to help reduce your electricity usage without losing comfort:
- Use the Timer Function
Most split system air conditioners and ducted air conditioning systems come with a built-in timer. Setting the timer ensures your unit only runs when needed. For example, you can set it to turn off 30 minutes after you fall asleep or come on just before you arrive home. This avoids unnecessary energy use while still keeping your space comfortable. - Switch to Fan-Only Mode When Cooling Is Not Needed
On milder days, running the unit in fan mode instead of full cooling can help circulate air without the full energy draw. It is a good way to stay comfortable while reducing your electricity usage. - Keep Doors and Windows Closed
This sounds simple, but it is crucial. Open doors or windows allow cool air to escape and hot air to enter, which makes your air conditioning system work harder. Make sure the space you are cooling or heating is sealed and well-insulated. - Clean or Replace Air Filters
Dirty filters restrict airflow, forcing the unit to run longer and use more energy. Replacing or cleaning your air conditioner filter every one to three months will help your system run more efficiently. This also improves indoor air quality, reducing allergens and dust. - Use Curtains or Blinds
Direct sunlight heats up your indoor space, forcing the air conditioner to work harder to cool it down. Closing blinds or curtains during the hottest parts of the day helps regulate indoor temperatures more easily. - Regular Professional Maintenance
A neglected air conditioner becomes less efficient over time. Booking a regular air conditioner service in Sydney ensures your system is working at its best. Technicians can clean the internal components, check refrigerant levels, and make sure your unit is running efficiently. - Upgrade to an Energy-Efficient System
If your unit is more than 10 years old, it could be using more energy than necessary. Modern energy-efficient air conditioners come with high star ratings and smart inverter technology. This means they automatically adjust their output to match the temperature needs of your space, using less electricity overall.
How Zoning Helps You Save
Zoning is a feature available in many ducted air conditioning systems, allowing you to control the temperature in individual areas of your home. Rather than cooling or heating the whole house, you can choose to activate specific zones, such as only the living room during the day and bedrooms at night. This targeted approach reduces energy use and saves money. If your current system does not offer zoning, ask your technician about upgrade options that include zoned air conditioning installation in Sydney.
Other Features That Help Reduce Power Usage
Many newer systems come with built-in energy-saving features. These include:
- Eco Mode: Reduces power consumption by running at a slightly lower output without affecting comfort
- Sleep Mode: Gradually increases the temperature overnight to reduce energy use while maintaining comfort
- Wi-Fi Control: Allows you to control your air conditioning unit remotely, so you can turn it off if you forget or schedule it to turn on before you arrive home
These features can often be customised to your lifestyle, ensuring comfort while saving money.
Signs Your System Is Wasting Energy
If you are noticing any of the following, it could mean your air conditioner is not energy efficient:
- Weak airflow from the vents
- Unit takes a long time to cool or heat
- Unusual noises coming from the indoor or outdoor unit
- Higher-than-normal electricity bills
- Air conditioner leaking water
- Controller blinking or system shutting off unexpectedly
In these cases, it is important to book an air conditioner repair with a qualified technician to assess whether cleaning, servicing, or replacement is required.
Choosing the Right Size Air Conditioner
One of the biggest mistakes that affects energy usage is installing the wrong-sized air conditioner. A unit that is too small will run constantly to try and reach the set temperature. One that is too large will cycle on and off frequently, wasting energy and increasing wear. To get it right, a technician should assess the size of the space, insulation, window exposure, and other factors before recommending the best system. At Vital Air Conditioning Services, we offer professional assessments to ensure your system is perfectly matched to your home or business needs.
Is It Time to Replace Your Air Conditioner?
Sometimes, saving on energy bills means investing in a more efficient unit. Older systems may still work but can cost you more in the long run. If your aircon is over 10 years old, frequently breaks down, or lacks inverter technology, it may be worth considering a new air conditioner installation in Sydney. Newer models are designed to meet modern energy efficiency standards, and the savings on your bills can offset the upfront cost over time.
Rebates and Incentives for Energy-Efficient Systems
Depending on your location in New South Wales, there may be government rebates or energy-saving incentives available for upgrading to a more efficient air conditioning system. These programs are designed to encourage households and businesses to reduce power usage. Our team at Vital can help you navigate these programs and determine your eligibility when installing a new unit.

For business owners, the cost of cooling or heating larger spaces can be significant. Here are a few additional tips tailored to commercial spaces:
- Install programmable thermostats to control usage during non-business hours
