What Drivers & Fleets Say
5.0 on Google read our reviews“We had a reefer go down while fully loaded with frozen product, and time was critical. Justin responded immediately, got out to our location fast, and had the unit back up and running without delay. I've trusted them with multiple trailers, and they've consistently delivered every time.”
“We've used AZ Mobile Diesel Repair a handful of times and they always do a great job. They are punctual, professional, and keep us updated. I really appreciate their attention to detail on both the truck repairs and the compliance paperwork.”
“Had an emergency seal leak on our tractor right middle of a job. Called a lot of mobile mechanics, most didn't answer but these guys did. Came out with the hour and got on back to work shortly after. They did clean work. Left it better than they found it.”
“I was stuck on the highway with a dead battery and the guys at AZ Mobile Diesel Repair came out within an hour. They fixed the battery issue quick, and they charged a fair price.”
