Honest Repairs. Reliable Service. Built Around Your Business.

Our founder spent nearly ten years repairing commercial trucks before opening EZ Diesel Repair. That experience shaped how we do business today. We believe customers deserve honest answers, quality workmanship, and repairs that solve the problem the first time.

Some repairs are straightforward. Others require experience, persistence, and creative problem-solving. We welcome those challenges because helping customers get back on the road is what drives us.

Repairing More Than Trucks

Our goal isn't simply to repair equipment. We want to help businesses stay productive.

Every recommendation we make considers your operation, schedule, and maintenance costs. If we identify a developing issue, we'll explain it clearly so you can decide what makes sense for your business. That transparency helps reduce unexpected breakdowns and gives you confidence in every repair decision.

Long-term relationships are built through trust, and we work hard to earn that trust every day.

Why Customers Choose EZ Diesel Repair

Customers return because they know they'll receive honest recommendations and dependable workmanship.

We communicate throughout the repair process, explain our findings clearly, and recommend repairs based on what your truck actually needs. If a repair is challenging, we don't walk away from it. We use our experience, resources, and industry relationships to find the right solution.

That commitment has helped us build lasting relationships with fleet managers, owner-operators, and businesses that depend on reliable trucks every day.

Built for Commercial Fleets

Fleet managers need more than occasional repairs. They need a shop that understands the cost of downtime.

EZ Diesel Repair works with commercial fleets to keep trucks operating safely and efficiently. Our maintenance and repair services help identify issues early, reduce unexpected failures, and support long-term equipment reliability.

We know your trucks generate revenue only when they're on the road. That's why we focus on accurate diagnostics, dependable repairs, and responsive service that helps you stay on schedule.

Mobile Service That Comes to You

A breakdown doesn't always happen near a repair facility. Our mobile diesel service brings experienced technicians directly to your truck whenever practical.

On-site diagnostics and repairs can reduce towing costs, shorten delays, and help your drivers return to work sooner. Our service vehicles are equipped to handle many repairs at your location, saving valuable time for both fleets and independent operators.

I drove from Utah to California to get my semi-truck repaired by Ezekiel; best price and quality of service I've ever found, they are truly good and honest. Also Bryan is a good mechanic.

Aero Mechanic

I've been a customer of EZ Diesel Repair for years. They've done right by me and genuinely try their best to get you up and running as soon as possible.​ Just today, one of my trucks had a cracked radiator. While one guy was removing the old radiator, another guy went to get the new one. They had my truck back on the road in 4 hours.​ They've done right by me and will do right by you.

New location, but I’ve been getting repairs done with these guys for a while now. Fair pricing, and quality work every time. Hard to find a diesel shop you can trust, but they always get the job done right. Definitely recommend them for any semi truck repairs.

Figured out exactly what was wrong with my truck so quickly I was like wow this is literally the easiest diesel repair I’ve ever seen in my life These guys are literal miracle workers. Worked with Danny and Ezekiel and Josh. Incredible incredible gentlemen. Lifelong client literally lifelong.

Amazing staff thank you very much. Staff was very kind and understanding. Dealership couldn't fix my truck for 7 days but here they fixed in one day. Staff do know what they are doing, they do actually work on your truck. Price is also reasonable and cheap. Even at 11pm they were working on my truck. All in all thank you so much guys amazing work.
