Polarised Electrical installs reverse-cycle heating and cooling across Melbourne's east. We size systems room by room rather than by floor area, check your switchboard and circuits before quoting, and do the electrical work in-house. Assessments are free and quotes are fixed.
Reverse-cycle splits and multi-heads, sized room by room and installed by the same licensed crew that handles the wiring.
A modern reverse-cycle system delivers three-plus units of heat for every unit of electricity — gas can't touch that.
We ARE the sparky: Most HVAC mobs quote the box and leave the electrical 'to your sparky'. We ARE the sparky: circuits, switchboard capacity and install in one visit, one warranty, one number to call.

Ryan and Jack did a great job doing the electrical work on my new 4 head split system. They got the job done in no time, and my split systems were up and running. Once connected, Ryan made sure all 4 heads were working. Thanks guys, great job!

The crew that answers when you call
Excellent service! The team arrived on time and completed the installation efficiently and up to scratch. Everything was done neatly, with great attention to detail. Ryan and Jack are top blokes and easy to deal with. Highly recommended!

Absolutely fantastic service and work done! The boys were super accommodating, answered any questions I had without a problem, left everything neat and tidy and overall did an amazing job installing our battery and inverter. Cannot recommend enough.

Zak and Ryan did a amazing job. Even with the obstacles of a double story home with a internal switch board they persevered in the heat and got the job done. Thanks guys we realy appreciate your work and polite attitude.

The experience is very nice with them. Specially Roy and Jack did their best. We are so much happy about their service. They heard every single word of us and suggest us which is good and why. Highly recommend

Depends on the room's size, insulation and sun — that's step one of the assessment. Oversizing wastes money; undersizing runs flat out.
Yes — a modern reverse-cycle system delivers three-plus units of heat for every unit of electricity. Gas can't touch that.
Yes — old units go as part of the job, and we can coordinate capping the gas line.
Most single splits are done in a day. Multi-heads take longer — your plan gives you a realistic timeline.
Anyone can say they're licensed. Here's what that actually means when we're on your job — and the paperwork you'll hold at the end of it.




You see the number, the inclusions and the exclusions in writing. If the scope changes on site, we stop and ask — we don't invoice a surprise.
No labour hire, no subcontractors. The electrician who quotes your job is the one standing in your switchboard, on the same REC (33326).
Every job finishes with a Certificate of Electrical Safety, tested circuits, a labelled board and photos of anything hidden behind a wall.
Workmanship guaranteed and manufacturer warranties registered in your name. If something plays up, you ring us — not a call centre in another state.
Luke · Founder, A-Grade electrician
Most of what's wrong with this industry comes down to one thing: the person selling isn't the person installing.
I'm a licensed A-Grade electrician, and so is everyone who'll be on your wall and in your switchboard. When we size a system, it's from your rooms and your bills — not the biggest box on the truck.
Book the assessment. Worst case, you'll know exactly what it takes to heat and cool your place without gas.
