"Tommy is very trustworthy and knowledgeable about auto repairs. Tommy has been servicing all the vehicles in my family for the past five years. I recommended him to family, friends and anyone who ask for a trustworthy mechanic. AAA+ service, good prices and friendly staff. Thanks Tommy – I am a customer for life!"

I have been using Tommy for over 5 years through several cars that had a lot of problems. I finally bought a Toyota, so I don't have to see Tommy very often now. He is the best mechanic I have ever had in my life. He was recommended by my cousin and her husband who had used him for a few years. He is so honest. I trust him totally with my car and he is always right. In the beginning, I would get a price from him and then call around to compare and he has always saved me money. He also works very fast. Most times when I bring it in with a problem, he has it diagnosed by noon and calls with the "good news" and tells me how much it will cost. His estimates are always true. He has never come back later and told me that it came out to cost more than he quoted. He would then order the part and get it the same day and do the work and my car would be ready by closing time that same day. I had a car that overheated and the head blew. He had the car for awhile waiting for the tool company to repair the head. He put it all back together and it was great after that. I can't recommend him enough because what is the most importannt thing is that I TRUST HIM AND WOULD AND DO RECOMMEND HIM TO ANY FRIEND THAT ASKS ME WHO IS A GOOD MECHANIC.

I have had Tommy at Quantum Mechanix work on 2 of my vehicles at multiple times and have received the best service from any mechanic's shop out there. They are extremely honest and reliable. Where mechanic's can be deceiving about work being performed, this is something you don't have to worry about with them. I have nothing but high praise for them. I cannot say enough good about this company.

Thanks Tommy for getting my Prius up on it’s maintenance today and getting that Amsoil Premier in there to keep me on the road delivering packages for Amazon Prime Now. The last thing I need is a mechanical failure because my livelihood depends on this car. Thanks to Tommy I know the repairs will be done to SPEC and my "baby" should keep me rolling on down the road for years to come. I have been to several mechanics now and Tommy by far blew them all away. I drive 30 miles and take a day off just to see him and after my first experience here I would drive a 100 miles if that is what it took to get here. Growing up in a mechanical environment I can tell when a mechanic knows his stuff and when he is just padding his invoice and Tommy is a true mechanic. The kind of guy you would send your mother to and know she was in good hands. With stand up guys like Tommy in this profession you’d be a fool not to take your car here first. The prices should be higher and I felt guilty paying such a great price for outstanding and professional grade service.

I recently took my Chrysler Town & Country van to Quantum Mechanix in Mansfield, Texas, for an oil change. I asked the owner, Tommy Frantzen, to also identify the mysterious whirring noise. Tommy took the van for a quick spin before pulling into the shop. He got out and said, ‘It sounds like a problem with your air conditioner compressor. The other sound I heard tells me that I better look at your front brakes, too.’ WOW! And I thought you had to look under the hood for car repair answers!

Which means that it only took two minutes for Tommy’s years of automotive experience to save me from two potentially dangerous highway situations. As it turned out, my front brakes were, ‘…probably good for another 20 miles or so before actual metal on metal...’ yikes! Tommy also took the time to explain that if the A/C compressor ‘seized up’ (he used more detailed technical language, of course), the engine would stop running. (With my luck… at midnight on a two-lane road in the fog with no cell phone reception.)

So, if you live in Mansfield, Arlington, Kennedale, Burleson, or within 25 miles of his location, I strongly urge you to take your car, van, or truck to Quantum Mechanix. Tommy Frantzen can provide you a prioritized list of recommended repairs or maintenance items because his primary goals are to prolong the life of your vehicle and to keep you and your family safe. Don’t wait until your ‘check engine light’ comes on... call Tommy to schedule an oil change and ask him to listen to your car.

I have been looking for a great, honest, and trustworthy mechanic since my old mechanic moved and I have now found Quantum Mechanix. Tommy worked on my Infinity and he knows his stuff. I will highly recommend him to all of my friends. Thanks Tommy for your hard work and customer service. I have found my new mechanic. I give you 5 stars.

I just moved to Texas from California and I have been trying to look for a (good, trustworthy, honest and affordable) mechanic for the past 11 months. After researching online, I have now found him! Tommy from Quantum Mechanix is quality! I called him this morning to ask for a quote and he gave me more than just a quote. He took the time to explain to me in detail about the job that I wanted to be done and its specifics. The vibe that I got from him already told me that this guy knew what he was talking about! I was not pressured to get any services done and he told me that when ever I was ready to come in! Another thing that blew me away was that he is an Amsoil dealer!! Now, if you have a mechanic who knows about Amsoil and all of its benefts, then you are in good hands! He was able to get the oil that I needed SAME DAY! When I took my car in for service he was very friendly and has a clean shop. One thing that I look for in my mechanic is that he allows me to watch the work that he does on my car and HE DID. That says a lot about him. There’s so much to say about Tommy from Quantum Mechanix that I can go on and on. All I can say is that he will be my mechanic forever!! Thanks Tommy! See you soon!!

Tommy came highly recommended to me. He was honest and upfront with me from the start. He quoted me a price. It stayed that price. He told me when it would be done. And it was. Very honest. I will be using him from now on. My car runs like a new car now. Thank you.

[I] want to thank Tommy for the quick repair of my radiator. I visited, he gave me an estimate, and when I returned, the radiator was on its last leg. The service was prompt and the truck was ready within the timeframe quoted. Thanks a bunch!! The truck is running GREAT!! WOO HOO!!!

Quantum Mechanix is the best!! Tommy was very friendly and knowledgeable, he fixed my air conditioning system quickly and for a great price. I will definitely be recommending him to my friends and my car club. Thank you.

I recently had my vehicle serviced at Quantum Mechanix and I was very impressed! Tommy replaced several items on my Eclipse and my vehicle feels like it’s new again. I never knew my vehicle could run so smoothly! I am definitely going to tell ALL my friends and family how awesome Tommy is. He was very honest and extremely knowledgeable unlike all the other shops that try to rip you off. Tommy, you have my business for life! Thanks.
