When beating the heat during scorching summers, a split system air conditioner becomes an indispensable appliance in every Australian household. These cooling wonders provide respite from the sweltering temperatures and contribute significantly to energy bills.

This guide will walk you through expert tips on how to get the most out of your split system aircon in keeping your living space and expenses cool.

Understanding Split System Air Conditioners

Split system air conditioners are a modern marvel in cooling solutions. They consist of two main components: an indoor unit (evaporator) and an outdoor unit (condenser). This configuration not only saves space but also enhances energy efficiency by allowing you to cool specific zones of your home.

13 Ways to Efficiently Maximise Your Split System Air Conditioning

1. Proper Sizing Matters

Choosing the right-sized unit for your space is essential. An oversized system may cool the area too quickly, leading to frequent on-off cycles and increased energy consumption. Consult with professionals to determine the ideal capacity for your needs.

2. Investing in Energy-Efficient Models

When purchasing a new split system air conditioner, look for models with high energy-efficiency ratings. While the initial cost may be slightly higher, the long-term energy savings will more than compensate for the investment.

3. Ideal Placement for Maximum Efficiency

To ensure your split system aircon operates optimally,  specialist heating and cooling technicians know how to choose a strategic location for installation. Placing the indoor unit on an interior wall away from direct sunlight and electronic devices that emit heat is necessary. This placement prevents undue strain on the system and facilitates even cooling distribution.


4. Smart Temperature Control

Setting the thermostat to an ideal temperature can make a noticeable difference in energy consumption. Aim for a comfortable yet efficient temperature, around 24-26°C during summer. Investing in a programmable thermostat enables you to adjust settings based on your schedule, further reducing energy usage.

5. Capitalising on Natural Ventilation

Before reaching for the remote, consider strategically cross-ventilating your space by opening windows and doors. This practice allows fresh air to circulate and can significantly reduce your air conditioner's workload, ultimately saving energy.

6. Insulation: A Shield Against Energy Loss

Proper insulation acts as a barrier against external heat, preventing cool air from escaping and hot air from seeping in. Seal gaps around windows, doors, and other potential leaks to create an energy-efficient cocoon within your home.

7. Night time Cooling Strategies

Leverage the cooler night time temperatures to your advantage. Open windows in the evening and early morning to let the cooler air in, then close them during the day to trap the coolness. This approach reduces the need for constant air conditioning during daylight hours.

8. Keeping the Filters Clean

Clogged filters restrict airflow and force your split system aircon to work harder. Clean or replace filters regularly to maintain optimal performance. A cleaner filter not only improves efficiency but also enhances indoor air quality. You can consider split system air conditioners that provide both cooling comfort and cost savings.

9. Regular Maintenance for Optimal Performance

Servicing a split system is crucial for prolonged efficiency. Regularly clean or replace filters, clear debris from the outdoor unit, and schedule professional maintenance at least once a year. This routine upkeep ensures unhindered airflow and prevents energy wastage.

10. Zone Cooling: Tailored Comfort

Split system air conditioners allow for zoned cooling, so you can cool specific areas as needed. Close doors to unused rooms and direct airflow to occupied spaces. This personalised approach saves energy by focusing on cooling efforts where required.

11. Curtains and Blinds: Partners in Cooling

Strategically using curtains and blinds can prevent heat gain from sunlight, reducing the strain on your air conditioner. Keep them closed during the hottest parts of the day to maintain a comfortable indoor temperature.

Ceiling fans

12. The Role of Ceiling Fans

Ceiling fans complement your split system aircon by promoting air circulation. Running fans with your air conditioner allows you to set the thermostat a few degrees higher without sacrificing comfort.

13. Monitoring Energy Consumption

Stay vigilant about your energy usage. Monitor your energy bills and analyse patterns to identify opportunities for further efficiency improvements. Small changes in habits can lead to significant savings over time.

Start Cooling Smarter Today!

With the knowledge gained about your split system air conditioner and implementing innovative cooling strategies to maximise its efficiency, you can create a comfortable living space while minimising energy consumption.

Incorporating these simple yet effective strategies into your daily routine can make a difference in how you use your split system air conditioning. By being mindful of your settings, maintaining your unit, and optimising your usage, you're not only ensuring a comfortable environment but also contributing to energy savings and a more sustainable future.
