Warm in July, cool in January, without gas
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.

One room is always too hot or too cold.
A single split on that wall. Most are in and running the same day.
A few rooms need help, but you don't want a row of boxes outside.
One outdoor unit runs a head in each room, and every room gets its own remote.
Old ducted gas that's noisy, slow to warm up and near the end of its life.
We take it out and put in reverse cycle that heats in winter and cools in summer.
Can't pick? You don't have to. That's what the free visit is for.
One of our licensed electricians walks through your home with you. We look at the rooms you're unhappy with, the sun they get, the insulation and your switchboard.
We show you which unit goes in which room, and why. You get one fixed price in writing. Take your time, we won't chase you.
Luke's team does the wiring, the new circuit and the unit, so there's nobody else to chase. We take the old unit away and leave the place clean.
If a smaller system will do the job, we'll say so. If now isn't the right time, that's fine too. Either way, you'll know exactly what would fix those rooms.
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!

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.

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!

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 heating and cooling system for a Melbourne home, 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.

Across Melbourne's east and south-east, Boronia to Berwick, Balwyn to Warrandyte.
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.
