Wall Split Air Conditioning


Wall split air conditioning units are ductless systems, and are generally used to cool or heat a single room. In some cases, you may require more than one system in a room (larger areas or joined living spaces). It is possible to have a wall split system for each room of the house, but generally this is less efficient (and more expensive) than installing a ducted reverse cycle system.

Wall splits come as two separate units, which are generally closely adjoined. One unit is installed outside of the house, while the other is mounted on the interior wall of the room that is being air conditioned.

Who should use a wall split system?


Wall split air conditioning systems are great for anyone wanting to heat or cool a single room.

In some cases, reverse cycle systems can be paired with wall split systems, especially if there are rooms that are semi-detached or have limited ceiling space.

What are the upfront and ongoing costs associated with running a wall split system?


Buying and installing a wall split system can cost anywhere from $1,500 to $5,000, depending on the unit and the configuration of your house. Ongoing costs can range from $150-$2,000 a year, depending on usage and size of the system.

Reducing the cost of running a wall split system


No one likes getting hit with a big power bill at the end of a quarter. Reduce the running costs of a wall split system by closing the doors of the room you are heating/cooling, and remembering to turn the unit off when the room is no longer occupied. Some units even have smart technology that can automatically adjust the temperature whether people are present or not.

Also, ask for an inverter system when making your purchase. Inverter systems ramp the fan’s power up and down as required, in response to temperature fluctuations in the room. This type of system will reduce energy usage, as opposed to a system that is constantly operating at full capacity.

Consider offsetting the cost of a wall split further by installing solar panels - drawing from energy generated by the sun, instead of drawing from the grid.
