Split AC Types: Choosing the Right System for Your Space

Posted in:
Split AC Types

When it comes to keeping your home or business cool during Australia’s hottest months, air conditioning is essential. But with so many different aircon systems out there, it can be confusing to know which one is right for you. One of the most popular and energy-efficient choices is the split AC system—but did you know there are various split AC types to choose from?

At Ready Electrical, we help Australians stay comfortable all year round by installing and maintaining the best air conditioning systems for their specific needs. Let’s explore the different types of split AC units and how they compare to other systems available in the market.

What Is a Split AC System?

A split system air conditioner includes two main parts: an indoor unit (usually wall-mounted) and an outdoor unit. These components are “split” apart and connected by pipes that carry refrigerant, making them quieter and more efficient than window or portable units.

Split AC systems are a popular choice across Australia due to their:

  • Energy efficiency
  • Quiet operation
  • Minimal installation footprint
  • Sleek design

But not all split ACs are created equal—let’s break down the most common types.

Common Split AC Types

1. Single Split System

Best for: Individual rooms
This is the standard wall-mounted unit most people are familiar with. A Single Split System cools or heats a single room and is ideal for bedrooms, home offices, or small living spaces.

Pros:

  • Affordable
  • Energy-efficient
  • Easy to install

Cons:

  • Only cools one space

2. Multi-Split System

Best for: Multiple rooms with limited outdoor space
A multi-split AC type connects multiple indoor units to one outdoor compressor. It’s perfect for homes or offices where several rooms need temperature control but there’s only space for one external unit.

Pros:

  • Custom temperature control per room
  • No need for multiple outdoor units

Cons:

  • More complex installation
  • Higher upfront cost

3. Ceiling Cassette Split System

Best for: Open-plan spaces
These units are mounted in the ceiling and blow air evenly in four directions. They’re popular in commercial settings or large homes where wall space is limited.

Pros:

  • Discreet look
  • Even air distribution

Cons:

  • Requires ceiling cavity
  • Higher installation cost

4. Floor-Mounted Split System

Best for: Rooms with limited wall space
Mounted low on the wall, these systems are perfect for homes with large windows or unusual layouts.

Pros:

  • Easy access for maintenance
  • Better air distribution for low-ceiling rooms

Cons:

  • Takes up wall space near the floor

How Do Split ACs Compare to Other Aircon Systems?

When deciding between split AC types and different aircon systems, it helps to know how they stack up against each other.

System TypeProsCons
Split SystemEfficient, quiet, flexible installationCools one area per unit
Ducted ACWhole-home cooling, hidden from viewExpensive to install and run
Window UnitsLow cost, simple to installNoisy, inefficient, blocks window
Portable UnitsMobile, no installation requiredNoisy, less efficient, limited cooling

For large homes, ducted systems might make sense, but for everyday comfort and energy savings, split systems are a great all-rounder.

Choosing the Right Split AC System for You

Here are a few tips to help choose the best aircon setup:

  • Room size: Measure your room in m² to ensure the unit’s cooling capacity (in kW) is suitable
  • Usage habits: Do you need AC in just one room or several?
  • Aesthetics: Wall-mounted or ceiling cassette?
  • Budget: Don’t just look at installation costs—factor in running costs too
  • Energy rating: The higher the star rating, the more you’ll save long-term.

Marcel and his team carried out the installation. They were on time, polite, explained what would be done and the time frame, and completed the work within that time. Removed all the rubbish, would recommend them for any AIRCON installation.

Ready Electrical and A/C installed my a/c some years back and have serviced it since. Greg and his team are first rate and Kane who has done the past couple of service calls has been most professional and thorough in servicing the a/c system. I fully recommend them for a/c sales, installation and servicing requirements.
