Our Auto-Electrical & Air-Con Services
At Direct Current Auto Electrics & Air-Conditioning, we save you the time and hassle of visiting a workshop. We bring fully equipped mobile service vehicles directly to your home, workplace, or job site in the greater Perth metro area. From minor diagnostic fixes to heavy-duty commercial upgrades, our trade-qualified team handles it all with over a decade of experience.
Mobile Auto Electrical Repairs
Electrical faults can be incredibly frustrating and hard to track down. Whether it’s a stubborn short circuit, a malfunctioning dashboard display, or a machine that simply refuses to start, we bring advanced diagnostic tools to you. We quickly locate and repair wiring faults, blown fuses, and component failures across cars, trucks, and heavy earth-moving equipment to get you moving again without the cost of a tow.
Airconditioning Repairs
Driving around Perth without working air-con is a nightmare you want to avoid. We offer comprehensive mobile climate control servicing, including leak detection, component replacement (such as compressors and condensers), and precise system re-gassing. We will make sure your system blows ice-cold air so you stay safe and comfortable, whether you're commuting to work or operating heavy machinery on-site.
Electrical Upgrades & Fit-Outs
If you need your vehicle tailored for a specific job or a massive road trip, we design and install custom 12V and 24V electrical setups. We specialise in complete electrical fit-outs for tradie canopies, 4WDs, commercial fleets, and marine vessels. Every wire is neatly routed, fused, and protected to ensure maximum reliability and safety under the harshest Australian conditions.
Dual Battery Systems
Planning an off-grid camping trip or need auxiliary power for your work gear? We supply and install custom dual battery configurations designed to keep your 12V fridges, camp lights, and power inverters running for days. By utilising smart isolation switches and DC-to-DC chargers, we ensure your secondary battery charges safely while you drive, without ever draining your vehicle's main starting battery.
Electric Brakes
Towing a heavy caravan, boat, or horse float requires serious stopping power. We install top-tier electronic brake controllers that ensure your trailer brakes seamlessly alongside your vehicle. Our mobile team handles the entire installation and calibration process, giving you peace of mind, smooth stopping control, and complete legal compliance on the highway.
Spotlight & Light Bar Installations
Factory headlights rarely cut it when you are driving rural WA roads at night or working on a dark job site. We supply and install high-performance LED spotlights and light bars that dramatically improve your night-time visibility. Every setup is professionally wired with dedicated switches and relays, ensuring clean integration into your vehicle’s existing electrical system.
Batteries & Alternators
A flat battery or a failing alternator can instantly ruin your day. If your vehicle is struggling to crank or the battery light is glowing on your dashboard, we can test your charging system on-site. We carry high-quality, heavy-duty replacement batteries and alternators, and we install them right where you are parked to prevent you from being stranded.
Electronic Fuel Injection (EFI)
Rough idling, poor fuel economy, and sudden stalling are often rooted in your vehicle’s Electronic Fuel Injection system. Using specialised scan tools, we read your vehicle's computer codes to diagnose faulty sensors, bad injectors, or fuel pump issues. We pinpoint the exact cause of your engine light glitches, restoring your vehicle's performance and efficiency on the spot.
