Your AC Installer Can't Switch It On Until the Electrical Is Done
The unit is up on the wall. The installer's done their part. But the system can't run until a licensed electrician wires it in, dedicated circuit from the switchboard, isolator switch fitted and the whole thing tested. Without the air conditioning electrical work, the installer can't commission the unit and you're sitting in a hot house with a brand new AC that does nothing.
The bottleneck is almost always the sparky. Your AC installer has done their job and now everyone's waiting on the electrical connection. A day's delay in summer means another night without cooling. For rental properties, it means a frustrated tenant and a PM chasing two trades to get one job finished. The faster the air conditioning electrical gets done, the faster everyone moves on.

Who Needs Air Conditioning Electrical Work?
Most of our air conditioning electrical work is split system installations, that's our bread and butter. But if you've got a ducted system or multi-head unit that needs wiring in, give us a call and we'll let you know if we can help.
Homeowners
You've bought the AC or your installer is ready to go. You just need the electrical connection done, dedicated circuit, isolator switch, wiring between indoor and outdoor units. You want an AC electrician who shows up when the installer does, gets it wired in and doesn't hold up the job. That's what we do.
Property Managers
A tenant's been approved for a new AC or the old unit is being swapped out. You need the air conditioning electrical coordinated with the installer, done in one visit and certified the same day. We talk to the installer directly, match their schedule and email you the compliance certificate without you having to chase it.
Landlords & Investors
Adding or replacing AC in a rental is a planned job, not an emergency. But it still needs the electrical done right. Dedicated circuit, isolator switch, correct cable sizing and a compliance certificate for your records. JOA handles the electrical side so your installer can finish and the tenant has cooling.

Questions Perth homeowners ask about Air Conditioning Installation
Common questions before booking. If yours isn't here, give us a call.
Call 0432 064 583Do I need an electrician to connect my air conditioner?
Yes. Any hardwired electrical connection to an air conditioning system has to be carried out by a licensed electrician. Your AC installer handles the refrigerant side — mounting the units, running the pipework, charging the gas. The air conditioning electrical — dedicated circuit, isolator switch, wiring to the switchboard — that’s a separate trade and it’s notifiable work.
Both trades need to finish before the system can be commissioned. We coordinate with your installer so it all happens on the same day where possible.
Can you coordinate with my AC installer?
That’s how most of these jobs run. The installer mounts the unit and does the refrigerant work, we handle the electrical connection — and ideally we’re on site the same day so the system is up and running before anyone leaves.
Give us your installer’s details and we’ll sort the timing directly with them. If they’re already on site and waiting on an AC electrician, call us — we prioritise same-day attendance for exactly this.
Does my air conditioner need a dedicated circuit?
Yes. Australian wiring standards require air conditioning systems to run on their own dedicated circuit. That means a separate circuit breaker in your switchboard wired directly to the unit — no shared loads with power points, lighting or other appliances.
A dedicated circuit stops the AC from tripping your safety switch under load and protects the unit from voltage issues. It also keeps your manufacturer’s warranty intact. If your switchboard doesn’t have room for an additional breaker, we’ll flag that in the quote and let you know what’s involved.
What's an isolator switch and do I need one?
An isolator switch is a manual disconnect fitted next to the outdoor unit of your air conditioner. It lets the system be completely de-energised for servicing or in an emergency without going back to the switchboard. Australian standards require one on every AC installation.
We fit the isolator as part of every air conditioning electrical job. It’s not optional — without it, the installation isn’t compliant and your AC installer won’t be able to sign off the commissioning.
How much does air conditioning electrical cost?
Depends on the setup. A straightforward connection where the switchboard is close to the unit and has spare capacity is the cheaper end. Longer cable runs, switchboard modifications or multi-head systems where more than one indoor unit is connected cost more.
Fixed quote upfront. No call-out fee. Tell us what unit is going in, where it’s going and where your switchboard is — we’ll send through a price. Usually within 24 hours.
