Installing an air conditioning system is a great way to improve comfort at home, especially during extreme weather. But along with the comfort of climate control, there’s a question on many homeowners’ minds: how will this installation impact my electricity usage? Understanding how different types of systems and usage patterns affect energy consumption can help you make informed choices and keep your bills manageable.
Types of Air Conditioning Systems and Their Energy Impact
Air conditioning systems come in various types, each with unique characteristics that impact electricity usage. Here’s a breakdown of the main types and their energy considerations.
Split System
Split systems are popular for cooling individual rooms. These units are generally energy-efficient because they are designed to cool smaller areas, reducing unnecessary electricity consumption. Choosing an energy-rated split system with inverter technology further enhances efficiency by adjusting power output to meet the desired room temperature.
Ducted System
Ducted air conditioning cools or heats the entire home through a system of ducts. While it’s convenient for whole-house climate control, it can consume more electricity if not managed carefully. Installing zone controls can help you minimise usage by cooling only specific areas when needed, reducing overall energy consumption.
Window Units and Portable Air Conditioners
Window units and portable air conditioners are suitable for single rooms but tend to be less energy-efficient than split or ducted systems. They often consume more electricity relative to the cooling they provide, making them best for short-term or occasional use.
Factors Influencing Electricity Consumption
Several factors determine how much electricity your air conditioning system will use. Consider these aspects to understand and manage the impact on your power bills:
System Size and Power Output
Choosing the correct size for your air conditioning unit is crucial. An undersized unit will struggle to cool the space, running constantly and consuming more power, while an oversized unit will cycle on and off frequently, using excess electricity. It’s essential to match your unit’s power output to the size of the room or area for optimal efficiency.
Energy Efficiency Rating
Most air conditioners are rated with a star system indicating their energy efficiency. Higher-rated units consume less electricity, thanks to inverter technology and other energy-saving features. Opting for a unit with a high energy rating can significantly reduce your electricity bills.
Thermostat Settings and Usage Patterns
Adjusting your thermostat and using the right settings can dramatically impact energy consumption. Setting the temperature around 24°C in summer and 18°C in winter will keep your space comfortable without overloading the system. Running the air conditioner only when needed and shutting it off in unoccupied areas also helps.
Installation Quality
Proper installation by qualified professionals ensures your system operates efficiently. Professional installation reduces energy leaks, ensuring all parts function optimally. Poor installation can lead to air leaks or inefficient operation, which can unnecessarily increase electricity usage.
Seasonal Electricity Usage
Your air conditioning’s electricity consumption can vary significantly with the season. Here’s how:
Peak Summer Demand
During summer, air conditioners often run for extended periods, increasing electricity usage. Using energy-saving features and maintaining moderate thermostat settings can help manage higher bills during peak demand.
Winter Heating with Reverse-Cycle Units
Reverse-cycle air conditioners can be used for heating in winter. While heating may use more electricity, a reverse-cycle unit is still more efficient than portable electric heaters. Moderate thermostat settings and limited usage in unoccupied rooms can help manage winter energy bills.
Tips to Minimise Electricity Usage After Installation
Following the installation, here are practical ways to keep your air conditioning energy-efficient:
- Routine Maintenance: Regular cleaning and maintenance are essential for optimal performance. Dirty filters and coils force the system to work harder, using more electricity. Clean the filters monthly and schedule annual servicing to keep your system in top condition.
- Smart Thermostats and Timers: Smart thermostats allow you to set timers and automate your air conditioner, ensuring it only runs when necessary. Many smart thermostats also provide energy-saving suggestions, helping to reduce consumption.
- Zone Control Options: In ducted systems, zoning allows you to cool or heat only specific rooms rather than the entire home, which saves energy. Limiting cooling to frequently used areas reduces unnecessary electricity use and keeps your bills manageable.

Financial Incentives and Rebates
In some areas, installing energy-efficient air conditioning systems can qualify you for rebates or incentives, helping offset installation costs and lower your energy expenses. Check with local authorities or energy providers to see if you qualify for rebates on energy-efficient aircon models.
In Summary
Air conditioning can significantly impact your electricity usage, but by selecting the right system, using energy-saving features, and following best practices, you can keep costs manageable. With careful planning and professional installation, air conditioning can add comfort to your home without drastically increasing your power bills.
