What has split air conditioning?

A split system air conditioner is one that is split into two systems: an indoor unit and outdoor unit. The indoor unit pumps cooled or heated air inside a home, while the outdoor unit helps to channel outdoor air into the system and directs it through refrigerant fluid that cools or heats it.


Types of split system air conditioning

Do you require both heating and cooling in your home? How big is your home, and how many spaces do you want to air condition? Choose the right type of split system for your needs. 

Multi-split systems

This type of split system works by having a single outdoor unit which channels air into two or more indoor units. These are a much cheaper alternative to ducted systems for homes where cooling multiple areas is necessary.

Reverse cycle split system

Reverse cycle split systems are perfect for climates where seasonal changes are felt, i.e. cold winters and hot summers. They can both heat and cool a home depending on what mode the system is set to. 

Cooling only split systems

Cooling only split systems are ideal for hotter or more tropical climates where escaping the heat is your number one priority! They are generally cheaper than reverse cycle systems.


What Size Split System Do You Need?

When it comes to choosing the best split system air conditioner: size matters! Size, or capacity, refers to the power output of a system. Excessively large split systems can increase your home’s energy consumption, while inadequately small split systems can overwork to maintain temperatures, which also increases energy consumption.

Is your home insulated? Insulation maintains your home’s temperature and prevents hot or cool air from escaping. This means insulated homes may require smaller split systems when compared to uninsulated homes. 

Room Size

Larger rooms, spaces and homes will generally need larger split systems and vice-versa. 

Windows & Doors

Windows and doors are a means of internal air escaping and external air entering your home. The more windows & doors, the more your air conditioner will have to work to maintain a set temperature. 

Orientation & Climate

Your home’s positioning will influence how much external heating it receives from sunlight. In addition, your local Australian climate will impact your needs, e.g. hotter climates need more powerful air conditioning units. 


Split System Air Conditioning Running Costs

One of the most important factors affecting your decision on the best split system air conditioner for your needs is running costs. There are a number of factors you should consider when selecting a split air conditioning unit that is right for your budget.

Inverter vs Non-inverter

Non-inverter split systems have much cheaper upfront purchase costs than inverter systems. However inverter systems optimise operational efficiency, saving you on energy bills in the long run.

Star Rating

An easy to understand concept when comparing similar split system air conditioning models: a higher star rating means the unit will be more efficient, require less energy and save you more money on your bills. 


The size of your split system air conditioner unit will affect your energy consumption,

Split System Features

Different and newer split systems have a variety of energy saving features such as timers, Eco mode and human presence sensors. Make sure the system you choose has the right set of features for your needs.

Operating Temperatures

The further you adjust temperatures away from the ambient outdoor temperature, the more energy required to power your air conditioning system. Choose a system that operates efficiently at the temperatures that suit your comfort.
