Split System Air Conditioner Adelaide

The Split System air conditioner is one of the most popular air conditioners for Adelaide homes. Traditionally, when someone thought of air conditioners, they would automatically picture a split system.

However, in recent decades, other types of air conditioners have also become very popular. These include the Ducted Air Conditioner (also known as Central Air Conditioning) and Evaporative air conditioner. So which type of air conditioner is best for homes in Adelaide?

This post shares some insights into this topic. We will compare the characteristics and benefits of the different types of air conditioners to Split Systems. And see if Split System remains the most suitable for home owners living in Adelaide.

What Is A Split System Air Conditioner?

Before we go further, let’s level set and ensure we know what the different types of air conditioners are. A Split System air conditioner comprises of a compressor (usually located on the outside back or side of a house), and multiple wall units. The compressor performs all the heating and cooling and the wall units expels the conditioned air into the room or space in a home. You will need to install a wall unit into each room that you want to air condition.

The Ducted Reverse Cycle(DRC) and the Evaporative Air Conditioner are both ducted air conditioners. They use ducts to distribute the conditioned air throughout a home.

The DRC comes with an internal and external compressor which produces the cold/warm air, which is then distributed throughout the home using the network of ducts and air vents.

The Evaporative Air Conditioner only has a main compressor which is usually mounted on the roof of the house. This compressor sucks warm air into it’s system, passes the air through dampened cooling pads, and produces cool air which it then distributes throughout the home.

The evaporative air conditioner uses a similar system of ducts to distribute the air. A key difference between evaporative cooling and DRC/Split System, is that it uses an evaporative process instead of a refrigerative process (which is used by DRC and Split System air conditioners).

Are Split System Air Conditioners Suitable For Adelaide Homes?

So just how suitable is the Split System Air Conditioner for homes here in Adelaide? It depends on a few important factors. Let’s take a look at some of these considerations below.

House Type and Layout

This is an important factor. The size and layout of a house has a big impact on how suitable a Split System would be for you. Since a split system requires wall units to be installed into each room you want to air condition, it is more suitable for standard size homes with the usual 2-3 bedroom layout.

These home layouts are very common in Adelaide, and that is the reason why Split System remains one of the most popular air conditioner choices. However, if you have a larger sized home, especially if it’s multi-storeyed, installing a split system may get cumbersome.

For example, if you have many rooms in your home, say 6-7 rooms, you would need to install that many wall units. Which also means you may need to install more than one compressor to support them.

This may become cost prohibitive in some cases as the total upfront cost may quickly escalate. So for larger homes with more complex layouts, and harder to reach spaces, a ducted air conditioner like the DRC or Evaporative may be more suited.

Efficiency Efficient

If you have a standard sized home, the Split System is really quite ideal. Both in terms of efficiency and practicality. Split System air conditioners nowadays all come with inverter technology which greatly improves energy efficiency. The inverter allows the air conditioner to scale up or down it’s power mode according to how much heating or cooling is require. This reduces wastage and significantly improves efficiency.

Generally, for the same usage intensity, it can be said that split systems take the middle ground in terms of efficiency and long term running costs. The DRC, given it’s capacity and ability to effectively take on larger homes, generally costs slightly more in terms of running costs.

And the evaporative, with it’s use of an evaporative process instead of refrigerants, costs the least in running costs. In fact, some manufacturers have provided that Evaps can operate at one-tenth the cost to run when compared to a DRC. So in terms of efficiency, the Split System is a good middle ground.


When it comes to usability and features, the Split System air conditioner comes up tops. Here’s why. Majority of the special end-user features are built into the wall units. Which DRC and Evaporative air conditioners do not have.

From multi-stage air filters with ionisers, to airflow controls to 3D sensors, the split system offers much more control and customisations than both the DRC and Evaporative air conditioners. Each wall unit is separately contolled via a remote controller which allows for much flexibility in usage.

The remote controls also host a wide spectrum of special features which allow you to customise every aspect of your home climate. From power modes, to louvre positions and air flow preferences, to timer settings. The split system truly offers much more control and usability.

Are Split System Air Conditioners Suitable For Adelaide Homes?

Again, if you have a standard sized, 2-3 bedroom home, split system would seem to be a great choice for your home in Adelaide. It comes with an impressive array of features and is fairly economical in terms of long term running costs. Split System air conditioners are also very easy to install and requires minimal service and maintenance. Just be sure to keep up with the periodic servicing in order to ensure your split system operates optimally – and maintains it’s life span.
