Heavy Equipment Repair in Phoenix
Heavy equipment repair is diesel service for the construction and industrial machines Phoenix contractors run, not just trucks. We diagnose and fix everything from a fault code to a full engine or component rebuild. Truck & Equipment Specialists handles it in shop or mobile across the Phoenix metro.

The same diesel we know inside and out powers the machines on your jobsite. Excavators, loaders, skid steers, and the industrial gear running around Phoenix all breathe, burn, and break down like any diesel engine, and that is exactly what we work on every day.
We are Truck & Equipment Specialists. Owner Jonathan has spent 10-plus years elbow-deep in diesels, and that hands-on knowledge carries straight over to your equipment. When a machine goes down it stops the whole job, so we come to you when we can and pull it into the shop when the work calls for it. Either way you get a real diagnosis and a straight answer, not a parts-cannon.
Diagnose the actual problem
We start by finding the root cause instead of guessing. We pull codes, test the fuel and electrical systems, and check the machine under real load so you know what is wrong before anyone orders a part.
Component repair and replacement
Fuel systems, turbos, cooling, hydraulics tied to the engine, sensors, and wiring. We repair what can be repaired and replace what cannot with OEM or OEM-improved parts so the fix holds up on the jobsite.
Complete engine repair
When a machine needs more than a patch, we handle major engine work through full component and engine rebuilds on construction and industrial diesels. Big jobs like this usually come into the shop where we have the space and tooling.
Emissions system service, done right
We diagnose, clean, repair, or replace emissions components with OEM or OEM-improved parts to get your machine running clean and legal. TES is a compliant Phoenix shop, so the work is done the correct way.
Mobile service to the jobsite
For a lot of repairs we bring the shop to you across the Phoenix metro so your crew is not standing around waiting on a tow. Less downtime, less lost time, machine back to work.
