Split System Air Conditioner

A split system air conditioner is one of the most popular and practical cooling and heating solutions for Australian homes. Climat supplies and installs high-quality split system air conditioners from leading brands including Daikin, Mitsubishi Electric, Hisense and Rinnai. These systems offer excellent performance, energy efficiency and quiet operation, making them ideal for individual rooms or smaller homes.

Whether you need a single split system air conditioner for a bedroom or a multi-split setup to cool several rooms, our team provides expert advice and professional installation tailored to your needs.

What is a Split System Air Conditioner?

A split system air conditioner consists of two main components: an indoor unit and an outdoor compressor. The indoor unit is mounted on a wall and delivers cooled or heated air into the room, while the outdoor unit houses the compressor and condenser.

The two units are connected by refrigerant piping and electrical wiring. This design allows for efficient operation and quieter performance inside the home compared to older-style window or portable units.

Single Split vs Multi-Split Systems

Single split systems feature one indoor unit connected to one outdoor unit. They are perfect for cooling or heating a single room and are generally more affordable to purchase and install.

Multi-split systems allow multiple indoor units to connect to a single outdoor unit. This option is ideal when you want to condition several rooms without needing multiple outdoor compressors. Multi-split systems offer greater flexibility and can be more cost-effective for homes requiring comfort in two or more areas.

Best Rooms and Sizes for Split System Air Conditioners

Split system air conditioners work best in individual rooms such as bedrooms, home offices, living areas and studies. They are particularly suitable for homes where only certain rooms need heating or cooling at different times.

Smaller rooms typically require systems between 2.0kW and 3.5kW, while medium-sized living areas often need 5.0kW to 7.0kW units. Larger open-plan spaces may require 8.0kW or higher. Correct sizing is essential for efficient operation and comfort.

Cooling-Only vs Reverse Cycle Split Systems

Cooling-only split system air conditioners provide effective cooling during warmer months. They are a good choice for areas that rarely need heating.

Reverse cycle split systems offer both cooling and heating from the same unit. This makes them highly versatile for Australian homes that experience both hot summers and cooler winters. Reverse cycle models are generally recommended for most households as they provide year-round comfort.

Frequently Asked Questions

How much does a split system air conditioner cost to run?

Running costs depend on the unit’s star rating, how often it is used and local electricity rates. High-efficiency inverter models can keep costs low, especially when used with timers or smart controls.

Can I install a split system air conditioner myself?

No. Installation must be carried out by licensed professionals. Incorrect installation can void the warranty and create safety risks.

How long does a split system air conditioner last?

With regular servicing, a quality split system air conditioner typically lasts between 10 and 15 years.

Do split systems require much maintenance?

Basic maintenance includes cleaning filters every few months. Professional servicing once a year is recommended to maintain efficiency and performance.

Is a split system suitable for a large open-plan area?

Yes, provided the correct capacity is chosen. For very large spaces, a multi-split system or ducted solution may be more appropriate.
