Split System Cooling - Air Conditioning Units

Split system air conditioning makes for a very comfortable cooling option. Thanks to their filtration capabilities, split systems offer an allergy and asthma-friendly home cooling method that won’t dry out the air.

Well-suited to both homes and businesses alike, split systems are ideal for buildings and spaces where ductwork is inefficient or non-existent. They come in a range of sizes to suit spaces as small as a bedroom or as large as an open plan office space.

Optima supplies and installs split system Air Conditioners from some of the industry’s most recognised names, including:

How Does Split System Cooling Work?

Split system air conditioning refers to an air conditioning system in which the compressor unit and the fan coil unit – the core components of a heating, ventilation and air conditioning (HVAC) system – are separated.

Typically, a unit housing the air conditioner’s compressor and condenser is placed outside of the room you wish to cool, and one or multiple indoor units are normally mounted on your walls inside. The user thus has the ability control the temperature of each room individually.


The split system’s indoor unit blows cool air around the room, while the outdoor unit dispels the hot air from inside. The unit uses refrigerants to cool the air being distributed inside.

With a reverse cycle setting, split system air conditioners can keep you warm during the colder months too, so you can maintain a comfortable temperature all year round.

As a result, split system air conditioning has become a popular choice amongst home owners looking for cooling and heating solutions, especially once you take into account the system’s relatively low cost and noise emission.

What Are the Benefits of a Split System Air Conditioner?


Aside from the significant savings to be made with split system cooling, many people are drawn to this system for its versatility.
With the ability to both heat and cool, you can enjoy using your split system all year round.

Modern Design

As they’re wall-mounted, split systems are well suited to apartments, rooms with limited window space, and buildings lacking central HCAV systems. Current models are also available in a range of modern designs to complement your home.

Multi-zone Control  

Available in multi-zone models, split systems allow you to program separate settings for up to four rooms using only one outdoor condenser unit. This can help you save significantly on running costs, as you’re only heating occupied rooms.


Convenience is also key to the appeal of split system air conditioning units. With a single condenser and compressor unit located outside of the home or building, you can have multiple wall-mounted air conditioning units heating and cooling your space.

Allergy Friendly

Split systems are also well-suited to allergy-prone households, as the system’s filters remove allergens, dust, humidity and impurities from the air, ensuring you breathe only clean air.

Quick & Easy Installation

A split system AC is quick and easy to install for an accredited air conditioning specialist like Optima. They provide a cost-effective cooling method, and each individual air conditioning unit has its own easy-to-use remote control, putting your ideal temperature at your fingertips.

Tips for Using Your New Split System

  • To control your energy use, set a timer. That way, you don’t have to worry about forgetting to turn off the cooling when you leave home
  • Select a system with an economy setting. This will maintain moderate temperatures and reduce your energy consumption
  • Close windows and doors while the cooling is on so the air doesn’t escape and you don’t waste energy
  • Keep the temperature between 24-25 degrees Celsius. Every degree below this could increase your power bills by as much as 10% 
  • Clean your system’s filters and arrange for regular maintenance checks to ensure its operating to its full capacity
