Commercial Vehicle Repair

Your commercial vehicles are tools that have to work. We service and repair them with the same root-cause approach we bring to everything — minus the downtime games.

Signs you may need commercial repair

A work truck or van is down and you need it back
Check engine light on a commercial vehicle
Recurring problem nobody's actually fixed
Diesel work truck losing power or hard to start
Brakes, drivetrain, or electrical acting up under load
Equipment that has to run and isn't

Your commercial vehicles are tools, and a tool that doesn't work costs you a job. We service and repair work trucks, vans, and equipment with the same root-cause approach we bring to everything else, so the problem gets fixed once instead of coming back next week.

Find the real problem the first time

Parts-swapping is expensive on any vehicle, and on a commercial rig it's downtime on top of the parts bill. We diagnose based on how the system actually works, confirm the cause, and fix that, so you're not back in the shop in a month chasing the same fault. That's the whole point of an engineering-based approach, and it matters most when the truck has to earn.

Gas and diesel, under one roof

From a gas cargo van to a heavy diesel work truck, we cover the engine, transmission, brakes, electrical, cooling, and charging systems. We specialize in diesel, including Duramax, Cummins, and Power Stroke, so the trucks that are hardest to diagnose are right in our wheelhouse.

We respect your uptime

We know a commercial vehicle sitting still is a problem, not an inconvenience. You get a straight diagnosis, an honest timeline, and a call before any extra work, so you can plan around the repair. Serving Athens and Northeast Georgia, our job is to get your vehicles back to doing theirs.

Commercial Repair — common questions

Do you work on commercial diesel trucks?

Yes, diesel is a specialty of ours, including Duramax, Cummins, and Power Stroke. We handle the diagnostics, fuel and injection, turbo, cooling, and emissions service that keep a diesel work truck running and legal.

My van keeps having the same problem after other shops 'fixed' it. Can you help?

That's exactly the kind of work we're built for. Repeat problems usually mean the real cause was never found, just the symptom. We diagnose to root cause and fix the actual issue so it stops coming back.

What if my truck can't be driven to you?

If it won't make it to the shop, our towing partner Athena Towing can bring it in. Arrange the tow through us ahead of time and in some cases we can reduce or cover it when we do the repair.
