About Us

Built on Hard Work, Kept Running

On Demand Diesel Repair started with a simple idea: diesel owners in Titusville deserved a shop that treats their vehicles with the same seriousness they do. Not every garage understands the difference between a CP4 and a CP3 — but we do.

We've spent over a decade working on the engines that power this community — from daily work trucks and RVs to heavy commercial equipment. Our team holds ASE certifications, stays current with the latest diagnostic technology, and genuinely cares about getting the job right the first time.

Transparent pricing — no hidden fees or surprise charges

All makes and models — Cummins, Power Stroke, Duramax, and more

Warranty-backed repairs for your peace of mind

Emergency and same-day service when you need it most

Why Choose Us

The Difference Is in the Details

Most shops bolt on parts. We figure out why the part failed in the first place — so it doesn't fail again.

Expert Diesel Knowledge

Our technicians specialize in diesel powertrains. We know what makes these engines tick — and what makes them quit — because we've seen it all.

Honest Assessments

We'll tell you what your vehicle actually needs, not what's most profitable. If a repair can wait, we'll say so. If it's urgent, we'll explain why.

Modern Diagnostic Tools

Factory-level scan tools and advanced diagnostics let us pinpoint issues fast — saving you time and money compared to guess-and-check approaches.

Convenient Titusville Location

Easy to find off Bobbi Lane with plenty of parking. We offer flexible scheduling and quick turnarounds so you're back on the road sooner.

Testimonials

What Our Customers Say

Don't take our word for it — hear from the truck owners and fleet managers who trust us with their vehicles.

"Brought my 2015 F-250 in for a no-start condition that two other shops couldn't figure out. On Demand diagnosed it in under an hour — cracked fuel line. Fair price, fast turnaround, and they explained everything clearly. This is my go-to shop now."

Michael R. Titusville, FL

"I manage a small fleet of work trucks and On Demand handles all our maintenance now. They're reliable, communicative, and they never try to sell me things I don't need. That alone is worth more than you'd think."

Steven T. Cocoa, FL

"Had a DPF issue on my Cummins that was making the truck go into limp mode. These guys knew exactly what to do — cleaned the system, checked the sensors, and had me back on the highway the same day. Couldn't ask for better service."

Danny P. Merritt Island, FL
