Air Conditioning & EV Charging in Brisbane & Logan

Two of the biggest electrical jobs homeowners are tackling right now are adding proper aircon and setting up a home EV charger. Both look simple on the surface. Both can go sideways fast if the electrical side isn’t thought through.

Split-System Air Conditioning

Sizing and placement matter more than brand

An undersized unit runs flat-out and never gets the room cool enough. An oversized one cycles on and off constantly, doesn’t dehumidify properly, and burns out sooner. We look at the room size, ceiling height, insulation, and window orientation before recommending a unit, not just whatever’s on special at the hardware shop.

Placement affects efficiency too. The indoor head unit needs to throw air across the room without blowing directly on you. The outdoor condenser needs adequate clearance and airflow, and ideally not baking in western sun all afternoon.

What’s involved

We supply and install split-systems from reputable brands, or install a unit you’ve already purchased. Every installation includes:

• Electrical supply from your switchboard to the indoor and outdoor units
• Refrigerant line-set run and insulation
• Drain line to a compliant outlet point
• Full test and commission
• Electrical compliance certificate on completion

Installers in Queensland must hold both an electrical licence and an ARCtick refrigerant handling licence. We hold both.

Home EV Charger Installation

Don’t rely on a power point

Plugging your EV into a standard GPO with an extension lead is slow and not designed for sustained overnight charging loads. A dedicated EV charger, a wall-mounted EVSE unit on its own circuit, charges faster and is far safer long-term.

Single-phase vs three-phase

Most homes in Brisbane and Logan are single-phase. A 7 kW single-phase charger will fully charge most EVs overnight. If you’re charging a large-battery vehicle or want faster top-ups, a three-phase supply (32 A) can charge at up to 22 kW, but your home needs a three-phase connection from the street, and not all do.

We’ll check your existing supply before recommending a charger type.

What about the switchboard?

An EV charger puts a sustained load on your board that most older switchboards weren’t designed for. Before we install anything, we check:

• Available capacity in your switchboard
• Whether you have safety switches (RCDs) on all circuits
• The condition of your main earth and metering

If your board needs upgrading first, we’ll quote that separately and clearly. See our switchboard upgrades page for more detail.

Signs You Need One of These Jobs Done

• Existing aircon isn’t keeping up on 35°C days, or it’s more than 12–15 years old
• You’ve just bought or ordered an EV and want a proper home charger before it arrives
• You’re running an extension lead to your car overnight (this is the time to fix it)
• You’re adding solar and want to make the most of daytime generation with a smart EV charger

Honest Cost Factors

Aircon installation cost depends on: unit size (kW output), single-head vs multi-head, how far the line-set needs to run, and whether the outdoor unit needs a bracket or a concrete pad. A straightforward single-split install for a standard bedroom or living area typically ranges from $800–$1,500 supply and install, but a multi-head system across several rooms is a different scope entirely.

EV charger installation typically runs $800–$1,800, depending on how far the new circuit needs to run from your switchboard, whether conduit is required, and the charger model. Three-phase charger installs usually sit at the higher end. If your switchboard needs work first, that’s quoted separately.

We give you a fixed price before we start. No surprises.

Common Questions

Can I get aircon and an EV charger quoted in the same visit? Yes, and it usually makes sense to do both at once. One site visit, one compliance certificate, and we can think about the switchboard load holistically rather than piecemeal.

Do I need to buy the aircon unit myself? Either way works. We can supply and install, or do install-only if you’ve already purchased a unit. Just check the model with us first, some cheaper imported units aren’t worth the labour to hang.

What brands of EV charger do you install? We install most major brands, Zappi, Wallbox, Ocular, Evnex, and others. If you’re unsure which suits your car and setup, ask us when you book and we’ll give you a straightforward recommendation.
