Four Seasons, One Reliable System: Your Guide to Split System Efficiency
Australia’s diverse climate, particularly in Melbourne, means we experience the full spectrum of seasons. From scorching summer heatwaves to biting winter chills, a reliable heating and cooling system is essential for year-round comfort. For many Melbourne homes, the split system air conditioner has become the go-to solution. But are you maximising its efficiency? This guide delves into how to optimise your split system’s performance, ensuring it serves you reliably through all four seasons.

Understanding the Split System’s Versatility
A split system air conditioner comprises two main components: an indoor unit and an outdoor unit. The indoor unit circulates air within your room, while the outdoor unit houses the compressor and condenser. This design offers flexibility in installation and allows for zoned climate control, meaning you can heat or cool specific areas of your home. This versatility is crucial in Melbourne, where temperatures can fluctuate dramatically within a single day.
- Heating and Cooling in One: Unlike single-function heaters or coolers, a split system provides both heating and cooling capabilities, making it a cost-effective and space-saving solution.
- Zoned Comfort: You can control the temperature in individual rooms or zones, allowing for personalised comfort and reducing energy waste.
- Improved Air Quality: Many modern split systems come with advanced filtration systems that remove dust, allergens, and other airborne particles, contributing to a healthier indoor environment.
Maximising Efficiency in Summer
During Melbourne’s sweltering summers, your split system works hard to keep your home cool. To ensure optimal efficiency and minimise energy consumption, consider these tips:
- Set the Thermostat Appropriately: Aim for a temperature between 24°C and 26°C. Each degree cooler can significantly increase energy usage.
- Use the Timer Function: Program your system to turn on shortly before you arrive home and turn off when you leave. This avoids unnecessary operation when you’re not present.
- Keep Windows and Doors Closed: Prevent hot air from entering your home by ensuring all windows and doors are tightly sealed.
- Shade Your Home: Use blinds, curtains, or awnings to block direct sunlight and reduce the heat load on your air conditioner.
- Regular Filter Maintenance: Clean or replace your air filters regularly. Dirty filters restrict airflow, forcing your system to work harder and consume more energy.
- Professional Servicing: Schedule annual servicing with a trusted company like Legacy Trade Services. Our expert technicians can identify and address potential issues, ensuring your system operates at peak efficiency.
Staying Warm in Winter
Melbourne’s winters can be bitterly cold, requiring a reliable heating solution. Your split system can efficiently heat your home, but proper usage is essential to minimise energy costs.
- Set the Thermostat Sensibly: Aim for a temperature between 18°C and 20°C. Overheating your home wastes energy and can lead to discomfort.
- Use the Heating Mode Effectively: Ensure your system is set to heating mode and that the airflow is directed downwards as warm air rises.
- Seal Drafts: Check for and seal any drafts around windows and doors to prevent heat loss.
- Utilise the ‘Heat Pump’ Function: Most modern systems use a heat pump, which is more energy efficient than traditional electric heating.
- Regular Maintenance: Check that your outdoor unit is free from obstructions, such as leaves or snow, which can impede airflow.
- Professional Inspection: Legacy Trade Services recommends a pre-winter check-up to ensure your system is ready for the colder months.
Spring and Autumn: Transitioning Seasons
Spring and autumn in Melbourne are characterised by fluctuating temperatures. Your split system can help maintain a comfortable indoor environment during these transitional seasons.
- Use the ‘Dry’ or ‘Dehumidify’ Mode: During humid days, this mode can remove excess moisture from the air, making your home feel more comfortable.
- Take Advantage of Natural Ventilation: Open windows and doors during mild days to allow fresh air to circulate, reducing reliance on your air conditioner.
- Monitor Temperature Fluctuations: Pay attention to weather forecasts and adjust your thermostat accordingly to avoid unnecessary energy consumption.
- Check for Leaks: Inspect your system for any leaks or damage that may have occurred during the previous seasons.
- Schedule a Maintenance Check: These seasons are ideal for scheduling routine maintenance with Legacy Trade Services, ensuring your system is prepared for the upcoming extreme temperatures.
