Servicing, repairs, auto electrical and air-conditioning across Sunshine Coast QLD. From Caboolture to Gympie and inland to Kenilworth. We come to you, onsite or roadside, so your gear is back working sooner.
Auto air-con work is regulated. BJC holds a current ARC refrigerant handling licence, so your regas and repairs are done legally, charged correctly and won't void your warranty.


BJC Mechanical and AC is a fully mobile workshop. We service and repair trucks, trailers, machinery and cars where they already are, whether that is your yard, a job site or the side of the road. Mechanical, auto electrical and air-conditioning all handled by the one team, so you are not booking three trades and losing three days. You get a written quote before any work starts, and we tell you upfront if a callout or diagnostic fee applies.

Onsite and roadside repairs
Mechanical, auto electrical and air-con
Servicing Caboolture to Gympie
Modern trucks and machinery are full of sensors, control modules and wiring that will happily point you at the wrong fault. We use proper diagnostic equipment to find what is actually wrong before anything gets replaced, so you are not paying for parts that were never the problem. Once we know the fault, you get a written quote and we get on with it.

We understand the importance of clarity and are here to provide answers to your most common queries.
We come to you. Servicing, repairs, auto electrical and air-con work are all carried out at your yard, job site or wherever the vehicle has stopped. The only jobs that need to go elsewhere are COI and roadworthy inspections, which we do not do.
We service the Sunshine Coast and surrounds, from Caboolture through to Gympie and inland to Kenilworth. If you are just outside that, call us anyway and we will tell you straight away whether we can get to you.
Trucks, trailers, heavy machinery, plant equipment and cars. Mechanical servicing and repairs, auto electrical fault finding and automotive air-conditioning, all in house.
Callouts carry a fee, and test and diagnostic work may also be charged. Quotes for general servicing and repair work can be arranged, though a site visit to quote may incur a travel fee. We tell you what applies before we come out, so there are no surprises on the invoice.
