You may be looking to cool and heat your home in a simple and energy-efficient way. In that case, a split system air conditioner might be just what you need. Many Aussie homes are choosing this option because it is quiet and easy to install.

What is a Split System Air Conditioner?

A split system air conditioner has two main parts: one inside your home and one outside. The indoor unit blows cool or warm air into the room, while the outdoor unit removes heat and pushes it outside. A pipe connects both units through the wall. The reason it’s called “split” is that the system is split between these two parts. It’s great for cooling or heating a single room or a specific area in your home.

Hence, they can be done for bedrooms, living rooms, and home offices. Some models come with reverse-cycle features, meaning they can heat and cool your space.

How Much Does Split System Installation Cost?

The cost can change depending on the size of the unit, the brand, and where you live in Australia. On average, you can expect to pay:

Small room (2.5kW unit): $600 – $1,200 (unit) + $600 – $900 (installation)
Medium room (5.0kW unit): $1,200 – $1,800 (unit) + $700 – $1,000 (installation)
Large room (7.0kW+ unit): $1,800+ (unit) + $900 – $1,400 (installation)

Split vs Ducted Air Conditioning

If you are deciding between a split and a ducted system, here’s a quick comparison:

Feature	Split System	Ducted System
Cost	Lower upfront and install	Much higher upfront cost
Coverage	One room per unit	Whole house cooling or heating
Installation Time	Quick (half-day to one day)	Can take a few days
Maintenance	Easy	Needs professional servicing
Energy Efficiency	High (if used per room)	Can be high if zoned properly

If you only need to cool and heat one room, go for a split. But if you are after whole-house comfort, ducted may be better. That’s the key difference in the split vs ducted air conditioning debate.
