Local Climate
Many Australians reside in a region with a moderately humid climate. Unfortunately, this implies that in order to keep us cool, our air conditioners will need to work harder, which will increase energy usage. Additionally, it means that some models of air conditioners are virtually useless in areas of the nation where humidity levels are especially high. Evaporative coolers, for instance, are not ideal in high humidity because extra moisture forms inside the air conditioner. A refrigerated system would be the greatest cooling choice for locations with high humidity levels.
How many rooms you would like to cool
Choosing a unit to cool a single room is relatively simple; however, cooling multiple rooms necessitates more careful consideration. For cooling a single room, window units or split systems are ideal. However, if you need to cool additional rooms on your property, you might want to consider a multi-split system or a ducted air conditioning system.

Reliability
When selecting an air conditioner, reliability is a crucial factor. As with the majority of pricey appliances, it pays to stick with a reputable brand, look for extensive warranty terms, and choose retailers with a solid track record of after-sale support.

Think about the space your chosen air conditioner will require and whether it will be appropriate for the location.
