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.

  • Belmont 3216
  • 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.

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.

Answers

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.
