Cooling an open-plan South Yarra apartment usually hits the same snag. You want a couple of rooms done, and there is nowhere to bolt a row of condensers along a balcony or a shared boundary. A multi-head split system answers that, running several indoor heads off one outdoor unit. It is the setup Martin Turnbull fits most on local apartments and townhouses, and he has run Smartlec Electrical Solutions since 2017. As a licensed A-Grade electrician who is also licensed to install split systems, he handles the unit and the wiring behind it as one trade. Tell us the rooms you want cooled and where the outdoor unit could sit, and a fixed installation price follows.
Why an open-plan apartment usually wants a multi-head system
A single head, one indoor unit paired with one outdoor condenser, is the right call when you are cooling a single bedroom or one living area. South Yarra runs more to apartments and townhouses with open-plan living and a few bedrooms off it, and that is where a multi-head earns its place. One outdoor unit feeds several indoor heads, so the lounge, the main bedroom and a study can each have their own head and their own thermostat. On a balcony or a tight side boundary there is rarely room for three separate condensers, let alone an owners corporation that would approve them, so one outdoor unit doing the work of three keeps the footprint small and the approval simpler.
Getting the capacity right is what makes either setup hold the room. It is measured in kilowatts and matched to the space. A small bedroom might want a 2.5kW head, an average living area something in the 5kW to 6kW range, and a wide open-plan zone more again. Ceiling height, glazing and afternoon sun all move it, which is why we size against your actual rooms rather than a chart. We fit the names you will recognise, Daikin, Mitsubishi Electric and Fujitsu among them, and tell you which suits the room and your budget before you commit.
Where the outdoor unit can go on a unit or townhouse
This is the part that decides an apartment job, and it is worth settling before the model on the wall. A standard install pictures a clear external wall and an easy spot at ground level. A South Yarra unit or townhouse often offers neither: the balcony is the only outdoor space, the side boundary is a metre from the neighbour's window, and the wall you would mount to may belong to the building rather than to you.
So the placement comes first. The outdoor unit needs airflow, a fixing that can carry its weight, and a position that will not push noise into a neighbour next door. From there the line set, the thin pair of pipes linking the indoor heads to the outdoor unit, has to reach it within the length the system is rated for. Where the unit sits on common property, or the pipework crosses it, owners corporation approval usually comes into it, so we factor in what the body corporate is likely to want before we quote rather than after. None of that is guesswork, which is why we look at the actual balcony and boundary instead of pricing it sight unseen.
What it costs, and the $99 that comes off when you go ahead
A multi-head with three heads is a different job to a single bedroom unit, and the number of heads, the line-run lengths, where the condenser lands and the state of your switchboard all move the figure. A price quoted down the phone is a guess at a job nobody has seen. So a $99 inspection covers Martin assessing it in person and handing you a fixed, itemised quote, and that $99 is waived in full the moment you go ahead. A straightforward single-head replacement we can often scope from a few clear photos. Either way the figure is locked before work starts, with any rebate you qualify for already in it, so the number you are quoted is the number you pay.
