They fixed the issue, and the car runs fine now. The only delay was waiting a little longer for a part to arrive, but that wasn’t really their fault. David kept me updated the whole time.

I took my 2018 RAM in for an a/c repair. I was also experiencing some overheating. He fixed my a/c, like new. He also put a new factory thermostat in. All is good now. I highly recommend him and his shop.

My alternator broke when I was driving down 35 late one Friday night with a van full of things from my son's apartment. Luckily, it was near Master Tech Service Center. It was hours from where we live, so I was nervous going to a place I knew nothing about. David took care of our problem quickly, efficiently, and at a fair price. It was so easy and pleasant dealing with this auto shop. We were back on the road by Monday night, and we drove 14 hours the next day with zero issues. We're so grateful for this shop!!

Brought my car in for an ac service, mechanic noticed I had no fluids in my car. So he kindly ensured my car was good to go! Will be returning if any further issues arise!

I took my truck to David Smith after the dealership completely botched the repairs. He quickly figured out what they missed: a miswired door harness that melted connections, a fake actuator replacement, and a mess of electrical tape where proper wiring should’ve been.
David’s the real deal—knows his craft, digs until he finds the problem, and gets the job done right. He’s upfront about pricing, no surprises, and you’ll get exactly what you pay for—quality work.
If you need someone who’s honest, thorough, and doesn’t cut corners, David’s your guy. Simple as that.

David is nothing short of a miracle worker and auto wizard! He correctly diagnosed and fixed our truck after buying from a dealership who was unable to diagnose the issue and performed faulty “repairs” which David then had to repair. He was super communicative every step of the way and walked us through what was wrong and how he planned to fix it. He even had the courtesy and foresight to have us come take photos of the errors the dealership made so we would have it as evidence. The most knowledgeable mechanic I’ve ever done business with and super nice guy!!!

I trust MasterTech with diagnosing any problem our family vehicles have and to get the work done properly and in a timely manner! I appreciate David not trying to upcharge for other services not needed and only working on the current issues! MasterTech is your shop to go to in the Alvarado and surrounding areas

AMAZING!!!! Last week I had to get my car looked at I had run out of options and I was already hanging on by thin strings. I tried one more places and I am so happy I did, David was amazing, quick, ad efficient. I had a check engine light on and every place I had went to mind you I went to 6 different mechanic shops, each one wanted an insane amount of money or had no time slots available for walk-in's. David had me in and out of the shop in a couple hours and ,money still left over for lunch.
HIGHLY REQUIMIENDED!!!

Pricey but peace of mind from being serviced by a professional at his craft is worth it for me. Came in due to wire damage by rodents under the hood.
