Postwar wiring, modern load, one dedicated circuit at a time
Split System Installation in Belmont
Belmont is postwar housing that has had three generations of appliances added to wiring designed for one. The rooms are straightforward to condition and the blocks are easy to work on. The board is where the job usually starts.

- Powercor network
- REC 37223
The short answer
Belmont 3216 is mostly 1950s to 1970s weatherboard and brick veneer, and the common obstacle is the switchboard rather than the room. A fair number still have ceramic fuses rather than breakers, and almost none have a spare way for the dedicated circuit a split system needs. On the low streets near Belmont Common, which flooded in 1952 and again in 1995, outdoor unit height matters. Powercor is the distributor here.

From one of our jobs
Multi-head systems share one outdoor unit

The other local factor is the river. Belmont Common sits on the Barwon floodplain and has flooded before, so on the low lying streets the height of an outdoor unit is a design decision rather than a matter of convenience.
The board comes before the air conditioner
Postwar stock at this scale means original boards are common, and a fair number still have ceramic fuses behind the door rather than circuit breakers. Every indoor head needs its own dedicated circuit and an isolator, and that circuit has to land on protection that meets current standards.
We test the board and the main earth as part of the assessment, then quote the circuit and any board work as separate lines. It is not an upsell, it is the order the work has to happen in, and seeing the two numbers separately is what lets you compare quotes properly.
Ceramic fuses
A board still on rewireable fuses needs replacing before new circuits are added, indicatively $800 to $3,500 or more.
Spare ways
Even a serviceable Belmont board frequently has no room left for another protective device.
The circuit itself
One dedicated circuit and isolator per head, an indicative $350 to $800 depending on the run back to the board.
Sizing 1950s and 60s rooms
These houses have 2.4 metre ceilings, which keeps room volumes modest, but weatherboard and early brick veneer walls with little or no bulk insulation lose heat quickly. The ceiling batts, where they exist, have usually compressed to a fraction of their rated thickness.
The practical result is that a 4 by 4 metre Belmont bedroom often wants 3.5kW where the same room in a Waurn Ponds estate house takes 2.5kW. Restoring the ceiling insulation first is the cheapest capacity available and it improves every room in the house rather than one.
3.5kW
The common Belmont bedroom answer, particularly with west facing glass or an uninsulated wall.
5.0kW
A postwar lounge open to a hallway, which is the standard layout in these streets.
7.1kW
A rear extension that added volume and glazing, or a knocked through living and kitchen area.
Outdoor unit height near the Common
Belmont Common sits on the Barwon floodplain and has flooded before, most notably in 1952 and again in 1995. On the low lying streets near the river, mounting a condenser on a ground pad at natural surface level puts expensive equipment in the path of the next event.
The fix is simple and cheap at installation: a raised plinth or a wall bracket that lifts the unit clear, with the isolator mounted above it. Doing that costs very little on the day and is the difference between a wet condenser and a replaced one.
Lift it
A plinth or bracket that puts the unit above the likely level costs far less than a replacement condenser.
Isolator height
Switchgear at the outdoor unit goes above the equipment, not beside it at ankle height.
Drainage
Condensate needs somewhere sensible to go on a flat block, not a puddle against the footings.
Replacing gas heating, and what it saves
Ducted gas and wall furnaces are everywhere in this housing, and most of them are near the end of their working life. Reverse cycle returns 3 to 4 units of heat per unit of electricity against 80 to 92 percent conversion for gas, which is roughly 28 to 36 cents an hour to heat a room instead of 50 to 72 cents.
For a typical household that is around $200 to $450 a year, and more again if the house can drop the gas connection entirely and lose the daily supply charge. Victorian Energy Upgrades supports this changeover with a discount applied straight to the invoice.
No income test
VEU requires the property to be at least two years old and a $200 including GST minimum contribution, and nothing about earnings.
Confirmed at quote
The program changed on 30 September 2026, so we put the current amount in writing rather than promising a figure.
Room by room
Splits in the rooms you actually use are usually cheaper to install and to run than replacing a whole ducted system.
Access, licensing and how we schedule
Belmont blocks are 550 to 750 square metres with a driveway down one boundary, so side access is usually there but narrow. That is generally enough room for more than one condenser, which keeps single head systems available where an inner Geelong cottage would force a multi head.
Belmont is about 65km from our Altona workshop. We book Geelong work in planned blocks, give you a nominated week and confirm the day closer to the time. Refrigerant work is under ARC licence and the electrical connection under REC 37223 with a Certificate of Electrical Safety on completion.
Clearance still applies
A driveway is access, not clearance. The unit needs room in front of the discharge face to breathe.
Inland spec
Belmont is not coastal, so standard condensers are appropriate and marine grade hardware is not needed.
Guaranteed work
12 month workmanship guarantee on top of the equipment warranty, with the paperwork issued on completion.
On the ground
Belmont specifics
- Original postwar boards are common and a fair number still run ceramic fuses, so the dedicated circuit a split needs frequently cannot be added until the board is dealt with.
- The 1950s and 60s houses here were wired for a fraction of a modern household load, so spare capacity is the constraint before anything is added.
- Belmont Common is on the Barwon floodplain and flooded in 1952 and again in 1995. On the low streets near the river, condenser and isolator height are part of the design.
- Blocks of 550 to 750 square metres with a driveway down one boundary usually leave room for more than one outdoor unit, so single head systems stay on the table.

Belmont questions
Not onto that board. A split system needs its own dedicated circuit with modern protection, and a licensed contractor will not add one to a rewireable fuse board. The replacement is quoted as its own line at $800 to $3,500 or more so you can see exactly what is air conditioning and what is the house being brought up to standard.
Because the walls are working against you. Weatherboard and early brick veneer with little or no bulk insulation, single glazed windows and compressed ceiling batts lose heat far faster than modern construction. A 4 by 4 metre room that takes 2.5kW in a Waurn Ponds estate house commonly wants 3.5kW in Belmont.
Up. Belmont Common is on the Barwon floodplain and flooded in 1952 and again in 1995, so on the low lying streets we mount the condenser on a raised plinth or a wall bracket with the isolator above it. It costs very little at installation and it is the difference between a wet unit and a replaced one.
In this housing, usually yes. Original batts in Belmont homes have commonly compressed to half their rated thickness and rear extensions often have none. Improving the ceiling can take a room from needing 5.0kW to 3.5kW, which saves more on equipment and running cost than the insulation costs to install.
Roughly $200 to $450 a year for a typical household, because reverse cycle heats a room for about 28 to 36 cents an hour against 50 to 72 cents for ducted gas. If the house can go fully electric, removing the daily gas supply charge is often the larger saving of the two.
No, and we would rather say so. Belmont is about 65km from our Altona workshop and we book Geelong work in planned blocks. You get a nominated week and a confirmed day closer to the time. If you need someone within hours on a 40 degree day, a Geelong based contractor is the right call.
