Reliable Inspections, Quality Service

Mod Plating Service

If you’ve made structural or safety-related changes to your vehicle, a mod plate may be required to meet Queensland Transport regulations. Servicing light and heavy vehicles, we inspect modifications such as engine swaps, seating conversions or suspension upgrades. Once approved, we issue and attach the mod plate, certifying the changes for legal road use and registration compliance.

Air Conditioning Re-Gassing

Over time, car air conditioners lose refrigerant and become less effective. We provide mobile air con re-gassing to restore cooling power and keep you comfortable. Our process includes checking for leaks, pressure testing and refilling the system with the correct gas—all done at your home, job site or wherever your vehicle is parked.

Frequently Asked Questions

  • What is a mod plate and why do I need one?

    A mod plate certifies that vehicle modifications meet Queensland safety and compliance standards. It’s required for structural or performance changes like seat conversions, suspension upgrades or engine swaps. Approved inspectors issue mod plates after checking the work complies with legal codes. Without one, a modified vehicle may be considered unroadworthy or rejected for registration.

  • What is car air conditioning regassing?

    Car air conditioning regassing replaces the refrigerant gas in your vehicle’s cooling system. Over time, gas leaks or breaks down, reducing airflow and cooling. Regassing restores performance, improves comfort and includes leak testing and pressure checks. It’s recommended every 1–2 years, especially in warm climates where the air con works hard.

  • How do I know if my car air conditioner needs regassing?

    Signs include weak airflow, warm air, bad smells, or strange noises when running the system. If cooling is inconsistent or ineffective, it likely needs a regas. A technician can check pressure levels and look for leaks. Delaying service may affect performance or damage system components like the compressor.
