Split system units are a type of heating/cooling system that is comprised of an internal wall-mounted unit, combined with an external unit called the compressor. These systems are connected by two small pipes that carry refrigerant. This system can heat and cool your home, effectively servicing areas up to 60 square meters. Split System units are the most common residential system, likely due to the aesthetically pleasing finish, large servicing capabilities, and generally lower cost to install.

It is important to note the difference between inverter and non-inverter systems. Inverter systems have an inverter in the compressor unit’s motor, which allows it to control the speed of the motor. This essentially allows the system to continuously regulate the temperature of the room. This means a few things. Firstly, it means that the system doesn’t cool/heat a room to the desired temperature and then turn off, then turn back on when it detects a temperature change. This constant ability to maintain temperature means that it uses significantly less energy and can save you around 30% in running costs. It also allows for faster cooling and is generally a quieter system.
