Get a few quotes for a split system in Hawthorn and one thing keeps surfacing: the unit gets priced like the whole job, and the wiring behind it is treated as someone else's problem. It is not a side issue. Martin Turnbull, a licensed A-Grade electrician who has run Smartlec Electrical Solutions since 2017, fits the unit and does that wiring himself, because a proper installation needs its own dedicated circuit, an isolating switch and enough room left in the switchboard to carry it. On a Hawthorn home that electrical half often decides the job, so having one trade sign off the lot beats juggling a fitter and a sparky. Tell us the room you want cooled and roughly where your switchboard sits, and a fixed price covers both sides.
The two halves of a split system install, and who does each
Every split system install is really two jobs. One is the visible half: the indoor head on the wall, the outdoor condenser, and the pipe run between them. The other is the half nobody photographs: a dedicated circuit back to the switchboard, an isolating switch beside the outdoor unit, and the board itself having the capacity and the right protection to feed a unit that draws steadily for hours on a hot day.
Most air-conditioning firms are set up for the first half only. They fit the unit, then bring in a separate electrician for the circuit and anything the board needs, which means a second booking, a second invoice, and a hand-off where nobody is clearly accountable if a fault turns up later. Smartlec works the other way around. Because Martin is an A-Grade electrician who is also licensed to install split systems, the circuit, the isolator, the switchboard check and the unit go in as one job under one licence. If your board needs attention before the system can go on, that is the same quote and the same warranty, not a separate contractor to chase. It is the same reason a Hawthorn homeowner often books cooling alongside broader electrical work or a Hawthorn electrician visit.
Sizing the system to the room: single head, multi-head
A system sized to the room holds the temperature without straining; one sized off a guess either runs flat out and never gets there, or short-cycles and wastes power. Capacity is measured in kilowatts and matched to the space, so a small bedroom might want a 2.5kW head, an average living area something in the 5kW to 6kW range, and a large open-plan room more again. Ceiling height, glazing and afternoon sun all shift the figure, which is why we size against your actual rooms rather than a sticker on the box.
Then it is one head or several. A single head suits a living area or main bedroom. Where a few rooms need covering, a multi-head off one outdoor unit keeps a single condenser on the wall instead of a row of them, and suits rooms used at different times. On brands we fit the names you will recognise, Daikin, Mitsubishi Electric and Fujitsu among them, rather than one we are tied to, and we will tell you which unit suits the room and your budget before you commit.
What a Hawthorn install costs, and the $99 that comes off
No installer can put a real split-system price on a website, and the reason is the electrical half as much as the unit. The model you pick, the wall the head goes on, the pipe run and the state of your switchboard all move the number, so a figure quoted down the phone is a guess at a job nobody has seen. We would rather come and look. A $99 inspection covers Martin assessing the job in person and handing you a fixed, itemised quote, and that $99 is waived in full the moment you go ahead. A straightforward replacement we can often scope from a few clear photos. Either way the figure is locked before work starts, any rebate you qualify for is already in it, so the number you are quoted is the number you pay.
