How much does a split system cost to install?
The installed price depends mostly on the size of the unit and on how far the pipework has to run between the indoor and outdoor units. A back-to-back install, with both units on either side of the same wall, is the simplest job. A longer pipe run, a second-storey or hard-to-reach outdoor position, a new electrical circuit and owners corporation approval for an apartment all add to it.
We don’t publish prices. A quote depends on the room and where the units can go. Ask for a written quote that names the unit model and capacity, the length of pipe included and any extras, so you can compare quotes like for like.
If the new split system replaces an old gas or electric heater, a Victorian Energy Upgrades discount may apply. The split system replacement page explains how that works.

What does a standard install include?
Package deals usually cover a back-to-back installation up to a set length of pipe. Before you compare a package with a local quote, check four things: how many metres of pipe are included and what each extra metre costs, whether the outdoor unit goes on the ground or on a wall bracket, whether the electrical connection is included, and whether taking away an old unit costs extra.
Who can install a split system in Victoria?
Two licences cover the job. Connecting the refrigerant side needs a refrigerant handling licence from the Australian Refrigeration Council (ARC). Its split system installation licence covers single-head split systems under 18 kW. The electrical work must be done by a licensed electrician, who has to give you a copy of a Certificate of Electrical Safety for that work.
Ask for the ARC licence number and the electrician’s licence number before work starts, and keep the Certificate of Electrical Safety with your home records. You can check an ARC licence on the ARC website.
