A standard back-to-back split system installation including wiring and
appropriate permits will cost approximately $600 to $800 depending on
season and quality of work. You may find them cheaper but you get what
you pay for. The potential exists for a poor installation to cause
expensive repair costs down the track and that should be considered. A
non-standard split system installation with brackets, ductwork, a long
run, or additional power requirements will obviously cost more. All
split installers in all states are required to be licensed by the
Australian Refrigeration Council and the person doing the wiring needs
to hold a restricted electrical licence at a minimum. You should also
get a certificate of compliance for the electrical work.
