CARB Clean Truck Check

Most heavy duty diesel vehicles that operate on California public roads are now required to obtain a Clean Truck Check from CARB-credentialed HD I/M testers. Stay compliant to avoid DMV registration holds and fines of $1,000+ per day, per vehicle.

  • "I recently called Archer & Company to repair and service my refrigerated trailer. Noah, the service tech, is an experienced transport refrigeration mobile mechanic. He was able to identify the problem with my Thermoking S600 unit and resolved the issues quickly. His service was excellent and gave me a fair price. I highly recommend Archer & Company to anyone looking for a dependable & trustworthy mechanic."

  • "I’ve tried for years to find a good mobile reefer tech. The big names don’t have time and it’s hard to even get them to call you back when you have a breakdown. I called Noah and he was on-site within an hour. Before he headed out he asked for trouble codes and a model number so he could bring parts if needed. He texted me with a ETA when he was on his way. The problem was diagnosed and fixed in less than an hour after his arrival. The service reminds of what it was like 20-30 years ago. A real professional. Thanks Noah!"
