Air Conditioning Services

A working aircon system is essential in North Queensland’s climate. We offer full automotive air conditioning servicing, including pressure testing, leak detection, re-gassing, and replacement of failed components.

Annual servicing helps maintain performance and prevent expensive failures. We service all major makes and models with ARC-approved techniques for safety and compliance.

Auto Electrical Services

Modern vehicles rely heavily on their electrical systems—and when something goes wrong, it can affect everything from engine performance to safety. Our team handles all auto electrical work, including diagnostics, battery replacements, alternators, starter motors, dual battery systems, trailer brake wiring, UHF installs and more.

Suspension & Brakes Repairs

Safe handling and stopping power are critical—and both rely on a healthy suspension and brake system. We offer full brake repairs and replacements, rotor machining, fluid flushing, and brake hose servicing. On the suspension side, we handle everything from shock absorber replacement to steering and driveline work. We’ll let you know if parts are worn, unsafe or nearing failure. Whether it’s an upgrade or repair, we’ll help you get a smoother, safer ride.

Clutch & Gearbox Repairs

If you're hearing grinding or having trouble changing gears, your clutch or gearbox could be the issue. We service and repair both automatic and manual systems, from minor fixes to full replacements or rebuilds. Our team can diagnose slipping clutches, worn bearings and gear engagement issues with accuracy, using the right tools and techniques. We’ll get your vehicle shifting properly again, so you’re not left stranded or driving with damaged components.

Frequently Asked Questions

  • How often should I service my car?

    Most manufacturers recommend servicing your car every 10,000 to 15,000 km or at least once a year, whichever comes first. However, this depends on how and where you drive. Frequent short trips, towing or harsh conditions like high heat or dust can wear components faster and require more regular servicing to prevent costly issues.

  • What are the signs my suspension or brakes need attention?

    Common signs include squeaking or grinding noises, a soft or spongy brake pedal, vibrations when braking, uneven tyre wear or the vehicle pulling to one side. Worn suspension may cause excessive bouncing, nose diving when braking or poor cornering. If you notice any of these, it’s best to get your vehicle checked.

  • Is a roadworthy certificate the same as a safety certificate?

    Yes. In Queensland, a roadworthy certificate is officially known as a safety certificate. It confirms that a vehicle meets the minimum legal safety standards. It’s required when selling a registered vehicle, transferring ownership or re-registering a vehicle. Inspections must be carried out by an Approved Inspection Station.
