AC Repair

In the heat of the summer, your AC is working overtime to keep you and your passengers comfortable. But when your AC unit breaks down, your truck can quickly become hot. And when it’s 100+ degrees, an open window offers little reprieve. 

AC problems often occur at the most inopportune times, which is why our team of certified technicians will troubleshoot the problem and provide a comprehensive solution. We also offer preventative maintenance services to help keep your AC unit in top condition.

Factory Scheduled Maintenance

egular maintenance helps identify issues early and avoid expensive repairs later. Each vehicle has its own factory scheduled maintenance recommendations. Our vehicle maintenance services include:

  • Break check
  • Light inspection
  • Tire rotation
  • Check suspension
  • Oil change
  • Check fluid levels and replace as needed


If your fuses are blown, your lights and electronics are malfunctioning or you’re having battery or alternator issues it’s time to give us a call. The complex electronics in today’s vehicles are both critical to uptime and difficult to address without the required tools and expertise. Not only is our team of technicians knowledgeable about various electrical systems, they can efficiently troubleshoot electrical issues in your diesel.


The suspension system is an important component in a truck. Not only does it give you a better ride, it has a significant impact on how well your truck tows and how effectively you can stop when you’re towing. 

We can service and repair all elements of the suspension system. Whether it’s breaks, shocks, or even suspension alignment, we can help.

Master Certified Technicians

Every technician at Gem State Diesel and Repair is a ASE Master Certified technician. That’s the highest qualification available for work on diesel engines. Just like other professionals, our technicians have continuing education and keep current on the new equipment and technology.

When you bring your diesel in, we’re not just updating it with the same parts that came on it, the ones that failed which caused the issue in the first place. We’re repairing it with the newer, improved versions of high-quality parts so you don’t have the same issue again.

At Gem State Diesel and Repair, we’ve been helping Idaho diesel owners get back on the road since 2010. With over 9,000 diesels repaired, if you’ve got a problem, chances are we’ve seen it and solved it. 

We’re your go-to expert for Ford Power Stroke, Dodge Cummins and Chevy/GMC Duramax engines. We stand behind our parts and our workmanship. That’s why we offer a 2 year, 24,000 mile warranty – double that of most dealers.
