Best Split System Air Conditioners Australia 2025

Q: How do I choose the right split system air conditioner for my home?

Choosing the right split system air conditioner involves several steps. First, determine the size of the area you want to cool or heat, as this will affect the kW capacity needed. Next, consider the star rating of the unit; higher ratings typically indicate better energy efficiency. Additionally, look into the cooling and heating efficiency of the models you are considering. Lastly, read air conditioner reviews to gauge customer satisfaction and performance over time.

Q: What is the importance of the star rating in split system air conditioners?

The star rating is crucial when evaluating the efficiency of split-system air conditioners. It provides an indication of the energy consumption versus the cooling or heating output. A higher star rating means the unit is more energy-efficient, which can lead to lower running costs and decreased environmental impact. Models from brands like Mitsubishi, Fujitsu and Daikin often excel in this area.

Q: Are inverter split system air conditioners better than non-inverter models?

Inverter split-system air conditioners are generally considered better than their non-inverter counterparts because they can adjust their cooling and heating output based on the current temperature. This results in more consistent temperatures, less energy consumption, and lower running costs. Most brands offer a variety of inverter models that are popular in the Australian market. Non-inverter models are not widely available anymore as they don’t meet the current energy efficiency ratings required.
