TITLE: Split system wiring paths that pass Melbourne council heritage checks
KEYWORD: Melbourne council heritage checks
BODY:
A split system installation on a heritage-listed Melbourne property often fails at the route, not the unit. Generic installers run white conduit across the front facade, punch a penetration through original render, and mount the outdoor unit in plain view. These wiring paths fail Melbourne council heritage checks before the system is ever tested. The fix is not a different air conditioner; it is a hidden route drawn before work starts, using original cornice voids, eave soffits, and internal wall cavities so nothing visible changes.
Need maybe 80 words. Good.
What Melbourne council heritage checks require
Melbourne council heritage checks are not about testing the air conditioner itself. They assess whether the installation changes the appearance of a protected building or streetscape. Under a heritage overlay, planners look at external conduits, wall penetrations, outdoor unit placement, and any change to original fabric such as render, weatherboards, brick, or decorative plaster. The assessment usually starts with photos and a written description of the route. If the proposed path keeps all new services hidden or inside existing openings, the application is far more likely to be approved. If the installer cannot show the route clearly, the council will ask for more detail or refuse the works.

Wiring paths that fail quickly
Some routes are an almost automatic fail for Melbourne council heritage checks. A conduit clipped along the front wall is the most common problem. Even a short exposed run from the indoor head to the outdoor unit can be enough to breach the heritage controls. Wall penetrations through original brick or stone are also heavily scrutinised, especially when they break through a decorative cornice or skirt. Outdoor units placed on the front facade, visible from the street, or fixed directly over original detailing create another objection. Condensate drains that drip across a painted surface or form a visible pipe also draw attention. Generic installers often choose these paths because they are fast. They do not understand that the route is a heritage issue, not just a refrigeration issue.

Routes behind original cornices
The most workable hidden path in an older Melbourne home uses the void at the junction of the wall and ceiling. The indoor head is mounted on an internal wall, and the interconnecting cable, refrigerant lines, and condensate drain run into the ceiling space through the wall cavity. From there, the line set can follow the perimeter behind the original cornice inside the ceiling void before exiting through a discreet eave or soffit opening. This keeps the entire wall surface clean. The cornice itself is not cut or removed; the services travel in the space behind it. An installer who knows heritage work will mark this path on a simple section drawing before cutting any plaster. That drawing shows the council assessor that the original cornice remains intact and only an invisible ceiling void carries the new wiring.

Under eaves and box gutters
When the line set reaches the outside, the exit point matters as much as the internal route. A penetration through a soffit or eave lining is much less visible than one through a front wall. The cable and pipework can be fixed along the underside of the eave, tight against the fascia or behind the gutter line, so it cannot be seen from the street. For a double-storey or parapet-fronted building, the eave may not be visible from ground level at all. The installer should avoid running the pipe across the roof surface or down a visible downpipe. Where the eave is original and decorative, the penetration should be made through a replaceable section or an existing vent, not through the moulding itself. A diagram showing the under-eave path with dimensions and fixing points often satisfies the heritage advisor without further questions.

Inside wall cavities and floors
Many older Melbourne homes have plaster walls on timber studs or brick cavities that can accept cabling without visible surface conduit. The indoor unit can be positioned so the interconnecting cable drops straight down inside the wall cavity to a subfloor or roof space. In weatherboard houses, the cable can run under the floor bearers and exit through an existing vent in the foundation. In brick terraces, the path may run through the roof space and then down an internal wall. The key is to avoid chasing new channels into original brickwork or cutting through decorative plaster. A heritage-conscious installer will test the cavity with a cable rod before promising a clean route, and will mark the route on the plan so the council can see exactly where the new services sit.

Documentation that passes council checks
Melbourne council heritage checks move faster when the installer submits a clear plan, not just photos of the unit. A simple line diagram should show the indoor unit, the route through the ceiling or wall cavity, the exit point under the eave or floor, and the final outdoor unit location.
