How much does split system installation cost in Berwick?
The installed price depends on your room and your home, so it is agreed once the job is assessed. The biggest factors are the unit’s capacity in kilowatts, how far the pipework runs between the indoor and outdoor units, whether the indoor unit goes on an upstairs wall, and whether the switchboard needs a new circuit.
A back-to-back installation, with the outdoor unit on the other side of the same wall, usually needs less pipework than a long run to the side or back of the house. Removing an old unit and any discount you are eligible for also change the final figure.
Ask for a written quote that lists the unit model, the installation work and anything excluded. That way two split system quotes can be compared line by line.
Victorian Energy Upgrades discounts on reverse cycle splits
The Victorian Energy Upgrades program offers discounts on approved high-efficiency reverse cycle air conditioners. Only accredited providers can apply the discount, and the program says retrospective discounts are typically not possible, so speak to an accredited provider before you buy or install anything.
The discount depends on the size of the new system and what it replaces, with larger amounts listed when a reverse cycle split system replaces a non-ducted gas room heater. The new unit must be approved under the program and carry a warranty of at least five years for homes, and any system being replaced must be more than two years old.
Eligibility and the final discount are confirmed by the accredited provider, not by this website.

What size split system does my room need?
Split systems are sized in kilowatts of heating and cooling capacity, and the right size comes from assessing the room. Floor area is the starting point. Ceiling height, insulation, window size and the direction the room faces all shift it, so a west-facing living room with large windows can need more capacity than a bigger room on the shady side of the house.
Give the installer the room’s approximate dimensions, the size of its windows, which floor it is on and when you use it. Let them recommend the capacity rather than choosing one from the old unit’s label.
Single split or multi-head?
A single wall split pairs one indoor unit with one outdoor unit. It suits a bedroom, a study or an open-plan living area.
A multi-head system runs several indoor units from one outdoor unit, which can help when there is only room outside for one unit. If that outdoor unit stops working, every room it serves loses heating and cooling. Ask the installer to compare a multi-head design with separate split systems for your floor plan.
