Split system installation in Traralgon

A split system is one indoor wall unit connected by refrigerant pipe to one outdoor unit, and it heats and cools a single room or open living area. Published Melbourne guide prices put a 2.5 kW bedroom unit, supplied and installed, at $1,250 to $2,625 and a 5 kW living room unit at $1,900 to $3,675. A Traralgon quote can land outside those bands because of travel, the wall the unit mounts on and the length of the pipe run, and the independent installer you are put in touch with sets its own price after looking at the room.

Why do Traralgon households put in a split system?

Bureau of Meteorology averages for Latrobe Valley Airport give a July mean minimum of 3.7 C, so heating is the main job a split does here. The same records show a January mean maximum of 26.8 C, which is why most people choose a reverse cycle unit that does both. The usual triggers for a single new split are:

• A lounge room heated by a portable electric heater that costs a lot to run and never quite warms the space.
• A bedroom or study at the cold end of the house that the main heater does not reach.
• An extension, granny flat or converted garage with no heating or cooling at all.
• A household that wants to try reverse cycle heating in one room before deciding what to do with the rest of the house.

If you need more than one room covered, a multi-split system for several rooms or ducted heating may suit better. The ducted versus split comparison sets those options side by side.

How big should a split system be for my room?

Energy Victoria’s Victorian Energy Upgrades factsheet on space heating and cooling gives a starting point based on floor area and heating output:

Room size	Example rooms	Heating output suggested
Small, up to 20 m2	Bedroom, study	2.5 to 3 kW
Medium, 21 to 40 m2	Larger bedroom, family room	3 to 5 kW
Large, 41 to 60 m2	Open lounge and dining	5 to 8 kW
Very large, over 60 m2	Open plan living, kitchen and dining	8 kW plus

Treat that table as a first guess. A room with a raked or high ceiling, little or no ceiling insulation, single glazed windows or gaps around doors loses heat faster and may need the next size up. The same factsheet suggests looking for a higher heating star rating on the energy label, because Victorians typically use more energy heating their homes than cooling them. An installer should measure the room and look at those factors on site rather than size the unit from a phone call.

An oversized unit tends to switch on and off often and can leave a room clammy in summer. An undersized unit runs flat out on the coldest mornings and still struggles. Getting the size right is the single biggest decision in the job.

Where should the outdoor unit go?

The outdoor unit needs good air circulation around it, according to the VEU factsheet, so a cramped side passage boxed in by a fence is a poor spot. Noise matters too. Think about where your own bedrooms sit and where the neighbour’s windows face before agreeing on a location. Energy Victoria’s reverse cycle air conditioner buyers guide suggests asking for the outdoor noise level and the heating and cooling capacity to be shown in the quote, so you can compare units on the same terms.

Other things that affect the outdoor position:

• Distance from the indoor unit. A short pipe run through one wall is the simplest install; a long run around the house or through the roof adds labour and materials.
• What the unit sits on. Common choices are a ground slab, a pad, or wall brackets where ground space is tight.
• Drainage. The outdoor unit produces water when heating, so it should not drip onto a path or doorway.
• Access for future servicing.

What does a careful installer check before quoting?

Check	Why it matters
Room measurements, ceiling height and insulation	Sets the heating output needed
Wall construction where the indoor unit mounts	Brick, weatherboard and plasterboard need different fixings and core holes
Pipe and cable route between the two units	Drives labour and the amount of copper pipe
Switchboard capacity and a spare circuit	A new dedicated circuit may be required
Condensate drain path	Indoor units produce water when cooling
Outdoor position and neighbours	Airflow and noise

A careful installer will also tell you if a split is the wrong answer for the space, for example a long open-plan area where one head cannot push warm air to the far end. If the quote is for a reverse cycle unit with a Victorian Energy Upgrades discount, it should come through an accredited provider and show the discount on the quote.

What happens on installation day?

1. The installer confirms the indoor and outdoor positions with you.
2. The indoor mounting plate is fixed and a hole is cored through the wall for the pipes, cable and drain.
3. The outdoor unit is set on its slab, pad or brackets.
4. Refrigerant pipes, the interconnecting cable and the condensate drain are run and fixed, usually inside a cover duct on the outside wall.
5. A licensed electrician connects the system to the switchboard on its own circuit.
6. The refrigerant side is pressure tested and evacuated before the system is commissioned and run in both heating and cooling.
7. You are shown how to use the remote, clean the filters and set timers.

A long pipe run, an upstairs wall or roof work adds time, so ask the installer to say in the quote how long the job should take.

What does a split system cost in Traralgon?

The only published price bands this site uses are Melbourne metro figures, GST included, from a guide checked in October 2026. Use them as a rough guide and expect a local quote to differ.

Unit	Typical room	Melbourne guide price
2.5 kW split, supplied and installed	Bedroom or study	$1,250 to $2,625
5 kW split, supplied and installed	Lounge or family room	$1,900 to $3,675

Costs rise for a long pipe run, a second storey, a switchboard upgrade, wall brackets, or a brand and model with a higher star rating. The heating and cooling cost guide for Traralgon lists every published band on one page. If you already have an old split on the wall and want it swapped, see split system replacement instead, because removing the old unit and its refrigerant is a different job.

You can send a split system enquiry at any point while you work through the sizing above; it is better to include rough measurements than to wait for exact ones.

Which licences apply to a split system install?

Two licensed trades are involved in almost every split install:

• Refrigerant work. The Australian Refrigeration Council says a refrigerant handling licence covers putting in and commissioning a split, even before any gas goes into the pipes. Federal law, the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989, sits behind that licensing scheme. You can check a technician on Look for the Tick.
• Electrical connection. Connecting the unit to your switchboard is work for a licensed electrician.

Sometimes one person holds both licences; often two tradespeople share the job. Our about page explains how enquiries are passed on and lists the public registers for checking each licence before you agree to anything.

Next step: describe the room

To get a useful split system quote, send your room details for a split system and include:

• The room’s length, width and ceiling height, or a rough floor area.
• Whether the ceiling is insulated and whether the windows are single glazed.
• A photo of the inside wall where you would like the indoor unit.
• A photo of the outside spot you have in mind for the outdoor unit.
• What you heat the room with now, for example a portable heater or a gas wall furnace.
• Your suburb, such as Traralgon, Tyers or Glengarry.

An independent installer that covers your area reads those details, contacts you and quotes the job if it suits them.
