Mobile Diesel Repair — General

A mobile diesel mechanic is a certified technician who travels directly to your truck's location — whether it's on the highway shoulder, at a job site, or in your fleet yard. Onsite Diesel Solutions dispatches fully equipped service trucks with diagnostic computers, tools, and common parts so we can perform repairs on the spot. There's no need to tow your vehicle to a shop. We handle everything from emergency no-starts to scheduled preventative maintenance, right where you are in Central Florida.

A traditional truck shop requires you to drive or tow your vehicle to their location, wait for an appointment, and potentially lose days of revenue. Mobile diesel repair eliminates all of that — we come directly to your breakdown location, fleet yard, or job site with a fully equipped service truck. You save time, towing costs, and get back on the road faster. Our technicians carry the same diagnostic tools and capabilities as a full-service shop.

We repair all makes and models of commercial diesel vehicles including semi trucks (Freightliner, Kenworth, Peterbilt, Volvo, International, Mack), tractor trailers, box trucks, flatbeds, reefer units, dump trucks, heavy equipment, diesel pickup trucks (Ford F-250/F-350, Ram 2500/3500, Chevy Silverado HD), and RVs with diesel engines.

Yes. Onsite Diesel Solutions of Central Florida LLC is fully licensed and insured. Our technicians have over 30 years of combined experience in diesel repair, including dealer-level training and certifications. We carry full liability insurance for your protection when working on your commercial vehicles.

You can reach us three ways: For non-emergency fleet maintenance scheduling, email is preferred so we can coordinate a recurring service plan that fits your operation.
