What Is a Split System Air Conditioner?

A split system air conditioner consists of two main components:

• An indoor unit mounted on an internal wall that delivers conditioned air.
• An outdoor unit that contains the compressor and heat exchange components.

These two units are connected by insulated refrigerant pipework and electrical cabling, allowing the system to efficiently transfer heat between the inside and outside of your property.

Most modern split systems are reverse-cycle, meaning they provide both cooling in summer and heating in winter from a single unit.

 

Benefits of Split System Air Conditioning

Split systems remain one of Australia's most popular air conditioning options because they combine performance, affordability and flexibility.

Energy Efficient

Modern inverter technology adjusts compressor output to maintain a consistent temperature while helping reduce energy consumption.

Heating & Cooling in One System

Reverse-cycle technology provides year-round comfort without the need for separate heating appliances.

Quiet Operation

Indoor units operate quietly, making split systems ideal for bedrooms, nurseries, studies and living areas.

Individual Room Control

Each unit operates independently, allowing occupants to control temperatures in specific rooms.

Lower Installation Costs

Compared with ducted systems, split systems generally involve lower upfront installation costs and less structural work.

Modern Design

Today's indoor units feature sleek, compact designs that blend with modern homes and interiors.

 

Is a Split System Right for Your Home?

Split system air conditioners are particularly well suited for:

• Bedrooms
• Living rooms
• Home offices
• Apartments
• Townhouses
• Smaller homes
• Individual rooms requiring climate control
• Home extensions
• Multi-room homes using multiple independent units

If you're looking to heat or cool your entire home from one central system, a ducted air conditioning solution may be a better option. Our team can help you compare both systems during your consultation.

Choosing the Right Split System

Selecting the right system involves more than simply choosing a brand or model.

We consider:

• Room size
• Ceiling height
• Insulation

• Sun exposure
• Number of occupants

Running Costs & Energy Efficiency

One of the biggest advantages of modern split systems is their excellent energy efficiency.

Factors that influence running costs include:

• Correct system sizing
• Inverter technology
• Home insulation
• Thermostat settings
• Filter cleanliness
• Regular servicing
• Outdoor temperatures

For many Australian homes, comfortable and efficient thermostat settings are generally around:

• Summer: 24–26°C
• Winter: 18–20°C

Pairing your split system with rooftop solar can also help reduce electricity costs by using solar energy to power daytime cooling.
