UPDATE: I just want to add that these guys are amazing, they go above and beyond and more importantly, they are FAIR. and they get the job done right, and with integrity. We will never bring our vehicles anywhere else but here. They exceed our expectations every time. What a great place! My husband has a f150 and after bringing his truck here he will never let anyone else touch it. More than fair, honest, and friendly. Fixed his truck in a day, and the cost was outstanding. We cannot reccommend this place enough! If you need a safe, honest, reliable and skilled mechanic shop.. Look no further. You wont be sorry. Thanks again guys for being awesome!

I have been bringing my 2500 Chevy diesel truck to Jonny and Chris since 2017 with them doing everything from injectors, suspension A/C with basic maintenance such as oil changes. I must say they get to the root of issues and get your vehicle running like new. With the service they give and the pricing is untouchable. They get 5 stars ⭐️ from me

Just picked up my wife's vehicle, thinking that it was going to be a whole lot more than what it was, if he would have told us it would have been more we would have never known but he is a trustworthy fair guy, he said the only thing that's wrong with it is the temperature gauge, and we thought it was more serious. I will definitely be returning back if anything else happens. I would recommend him to anyone

I can’t thank Johnny, Chris and Nathan enough for all they do on my trucks. The most recent job they completed for me was basically a ground up build on all things mechanical for my 95 F350 dually. They knocked out an engine swap, turbo, fuel system and all accommodating parts. Along with a suspension lift, a/c system, frame clean up and paint. Covid affected some parts availability, but Johnny was very good with communication and Chris was great explaining the technical side of the build. Overall it was a great experience and I’m happy to have the truck back. Certified techs are the only guys that work will work on my trucks.

I have been looking for a diesel pickup up truck and it will be my first diesel. I found a diesel truck and reached out to Johnny because I wanted to have an inspection done before I flew down to Texas from Michigan. He said, do not get that year, make, and model. He gave me tones of information and advice on what diesel truck to get. I am still looking for a truck but I am still calling Johnny before buying my first diesel truck. A huge thank you to Johnny. Great customer service.

I had just moved to Houston and was looking for a place to take my diesel truck to get some work done to it. This was the first place I called and Johnny answered immediately, while other places didn’t answer or get back to me at all. They made me feel like family and made sure everything was squared away perfectly even if it costed them more time and money. Johnny will always give an honest opinion and is never out to get your money. Got my truck back with new front end parts and an alignment, drives like a dream now. In my opinion it’s the only place to go.

Have used Certified Tech several times now and never wrote a review until today. These guys are top notch. Will do their best 100%. Never had to have a redo of past repairs. My diesel truck is running top notch, thanks to these guys. Certified Tech will only do work on my truck. NO ONE ELSE!

Johnny and team are top notch. Look no farther for a shop to work on your 2017 Duramax. I brought my truck in and they diagnosed the issue and return my truck ahead of schedule saving me 3 days worth of rental car fees. Look no farther for a excellent shop to repair your diesel no matter what brand of truck it is. Also very honest and extremely trustworthy. They will have my business as long as I own my Duramax. Thank!!!!

First time diesel owner. Bought the truck a couple years ago, and used Certified to go through the truck and make the necessary repairs. These guys have a wealth of knowledge when it comes to diesels and how to maintain them properly. This is now my 3rd time back for maintenance. Always get a call from Johnnie with a detailed description of what’s wrong and what needs replaced as well as a cost. Great communication skills throughout the vehicles repairs. I will not take my truck to any other shop. Highly recommend.

⭐⭐⭐⭐⭐ I can't say enough great things about this shop! It's hard to find an honest mechanic who does top-quality work without making you wait weeks, but they exceeded all my expectations. They were incredibly responsive, got my tuck in quickly, and the work was done in a timely manor. The pricing was fair, and they didn’t try to upsell unnecessary repairs. If you need a reliable, skilled, and honest mechanic, this is the place to go. Highly recommend!

I'm pleased to highly recommend this shop for their exceptional mechanical expertise. Their ability to accurately diagnose and troubleshoot my Ram’s internal motor issues was impressive. Throughout the process, they kept me consistently updated on my vehicle’s progress and provided logical, practical solutions. Their honesty, fairness, and trustworthiness make them a standout choice for any automotive need.

Certified Techs Auto & Diesel exceeded my expectations in fixing my F250 diesel truck. Johnny and Chris showcased precision and expertise, swiftly diagnosing and resolving issues. Impeccable service, transparent communication, and fair pricing make them my go-to for any auto or diesel needs. A dependable diesel shop in the area is hard to find, and you cannot just take them to anyone. These guys will diagnose properly and repair properly, the right way. I highly recommend!

First want to start they have great communication here. Just about everyday they called me informing me on my truck and the next day plan. Johnny and Chris both very great guys when it comes to quality work and service. My last guy was a parts guesser and i caught on to it after constantly back with bandage jobs done. I run a construction company. With that being said if one of my fleets is down I’m loosing money. This shop did what it took to get me up and running better than when I bought the truck. Put the truck to the test and drove it four days straight out of town with no issues. I used to work on cars but never diesel so certain things I fall short on knowing or diagnosing. I’m glad I was recommended to this shop by a good friend. I don’t leave reviews much but this shop deserves it. Thank you Johnny and Chris! Gained a new customer forusre!

It's very hard nowadays to find a mechanic that you could trust and feel comfortable with. I was referred to Johnny and could not be happier. You could tell right away that he was honest and transparent. His pricing is very fair, and I never felt like I was being upsold unnecessary work. Johnny and Chris are great and I highly recommend taking your vehicle there.

Certified Techs Auto & Diesel Repair has been great to work with. Johnny is honest, easy to talk to, and knows what he’s talking about. He explains what’s going on without trying to upsell or overcomplicate things, and the work has always been done right the first time. Fair pricing, solid work, and someone you can actually trust. Highly recommend.

I have and will always take my vehicles here. They are always extremely honest and very quick to help. I have had so many issues with a used car that I bought from a shop in Houston and every time I took it here and Johnny & Chris would always take care of it and explain anything that was wrong. They made sure I'm always well-informed and can feel confident in my decision to have them work on it. This is the only place I have recommended people to because of the service they provide and how well they treat people. Absolutely a great shop that you can trust!!

Took my truck in two days before Thanksgiving with my radiator completely shot. I picked up my truck the next day fully repaired. Excellent customer service, and unbelievable repair time. The outcome could not have been better. I was able to still travel and get to my family just in time for the holidays. I really appreciate their service and fair pricing. I will be a returning customer.
