Mikhail and his son were extremely helpful and very nice. They were prompt and respectful of my time. They completed the opacity smog check on my 2006 Fleetwood Expedition motorhome in approximately 45 mins. I will recommend this company to all of my friends.

Sharon Kramer
We were truly impressed with Clean Truck Check Testing from start to finish. When we first reached out, Sargon responded immediately and quickly gathered the details he needed to schedule our appointment. He was incredibly responsive.
Joe Ruggless
Sargon was amazing, came to my house to perform my CARB test on my RV. There was a problem with my paperwork because of another shop making a mistake. Sargon went above and beyond to help me resolve this issue. My RV is now compliant. Sargon will be my CARB from this point forward.
Foran Performance Horses
Sargon was fantastic to work with. He explained how to get our vehicle set up with the CARB and he came out for mobile testing promptly. He was also on time and very professional. Exceedingly knowledgeable about diesel systems and carb compliance. 10 out of 10 recommend!
Tina Shafer
Sargon at Mikhail HD Testing should be awarded 10 stars. I found his business through an RV forum and from the minute we communicated via email he started our process to make sure we were well prepared for our OVI testing.
Brad Scavone
Sargon was a pleasure to deal with. He was on time and efficient. Sargon also took time to answer all my questions and explain the entire process. I will use his services again and highly recommend him.
Taylor Austin
The Clean Truck Check inspection of my 2005 Class A motorhome was quick yet thorough. He explained everything clearly and answered all of my questions. If I could give more than five stars, I would. I'll be using him every time I need this inspection.

I highly recommend this business. He arrived on time, did the test and after went above and beyond the service. I had problems with CARB he contacted them and got the information I needed to complete my registration. He invested at least 3 hours of his own time to help me.
