Tom is a kind, honest, and a hard working mechanic. Was recommended by a coworker and will bring my car to him from here on out. Great place!! read more

Tom has been my mechanic on four different cars always gives you the best price always manufacturer products always honest and a great guy. I have referred at least five different people to him and every family member goes to him for our maintenance and service on our cars. read more

Not sure why the last review did not post. Did a whole front end work on my car and give it back to me saying there's strange noises coming out of your front end without giving me any idea what it was from... Car still sounds like creaking sounds when I turn the steering wheel a year later :( read more

Tom is phenomenal. A great and honest man. Knowledgeable and friendly. He's completely transparent and efficient when it comes to work on your car. If you're looking for an honest, genuine, experienced and friendly mechanic, this is the spot read more

He did a lot of work for me but then he went MIA on me! I will try to find someone closer to me.

Tom is a genuine, honest, and dedicated person. His prices are more than fair and his work ethic is impecable. He explained and showed me in detail what the issue was, and broke down the cost of labor and parts in its entirety. I am content and satisfied with his work. I highly recommend him, and 100% assure you that Tom is the best master in mechanics. read more

I don't wanna talk bad about this business but he left me in a terrible way that cost me over $1,300 outta pocket. For this reason it doesn't deserve my praise, what kind of mechanic takes a car apart and then 5 weeks later tells you they can't figure it out and that it needs to go to the dealer. Worst of all doesn't put it back together,literally dismantled my whole steering column and just left it sitting on the front seat costing me $1,000 for the dealer just to put it back how it was(pictures included). Also he orders me a new bumper for $300 that wasn't for my model of Mercedes again coming outta my pocket. AMG whisperer I think not, try AMG MOLESTER! read more

See all

Tom did an Excellent Job on my Mercedes Benz 2007 E350! He went above and beyond. Thank you Tom and Quantum Mechanics!

I highly recommend having Tom as your mechanic!! The value for the amount of work put into my audi was amazing, and not only did he get the job done quick, he explained what was wrong with my car every step of the way and gave me a thorough breakdown of what I was paying for. Since my check engine light came back on after the initial repair he also changed my spark plugs free of labor charge. Super kind and helpful guy read more

Been working with these guys long enough to discover They truly do Care about their reputation and in this industry Rep is everything ,,, Here's my reflection of Opinion .. Quantam is a Trusted Auto Shop and Tom is a Pleasure To Work with .. -Tommy read more

Tom is a competent and professional master mechanic in a day and age that honest mechanics are very rare to find. I have been going to him for my personal and business cats from several brands, and I'm always happy with the results. I highly recommend his establishment to anyone out there who's looking for a good and reasonably priced mechanic. read more

Tom is awesome...very honest and truly cares about his customers! I went to a local mechanic, by my home, and was fed a bunch of lies that seemed wrong to me. Tom at Quantum Mechanics was recommended to me by a friend who has been Tom's customer for years and worked on his many vehicles. Out of the long list of fixes the other mechanic told me i needed, Tom honestly informed me that my new used truck only needed brake pads and was in great shape! I will be using his services for all my vehicles in the future! read more

I recently bought a 2000 Mercedes Benz E430. I've been having some issues and couldn't figure out what they were. A friend of mine told me about this shop. So I drove down to Huntington Beach, I had Tom check everything out, worked his magic and everything is fine again! Didn't even charge me with a few small things that needed some adjusting. Tom is a great guy! I highly recommend him! Thank you, Tom! read more

I feel obligated to give my review and warn others regarding the lack of expertise and integrity demonstrated by this business owner. I had a very similar experience as Ali G. I brought my Porsche Cayman in for a simple oil change. Not only did Tom put in the wrong amount of oil, but in checking my coolant level (which I did not ask him to do,) he damaged the cap and float device causing all the coolant to slowly leak out. Eventually I broke down on the 405 freeway with smoke coming from the engine and had to be towed. That simple oil change caused me to have my vehicle towed to a dealership resulting in a bill of over $1,200 dollars and nearly destroying my engine. When I asked Tom to at least contribute some funds to repair the damage he caused, he repeatedly avoided responding to any of my calls, texts or e-mails demonstrating zero integrity. To me it's not even about the money at this point, its about a business owner who has proven he cares little his customers and refuses to make things right when he screws things up. Be forewarned and use him at your own risk. In my case he couldn't even do a simple oil change correctly and refused to step up and make things right for the damage he caused to my vehicle. Tom comes across as a nice guy until he gets his money and then has little regard for you or for standing behind his work. If you need your car to be properly serviced or repaired, find another place! read more

Tom is a great guy! He's helped me fix several vehicles from Jeep's to Mercedes! Great communication, great price make this location a great value. No one works harder and is more honest then Tom Huerta! read more

I drove all the way from Ontario to have work done on my Prius ac compressor and I will always go to him from now on. He is so honest he even charged me less on labor, which was already a fair price, cause it took much quicker to fix. Tom is an honest guy and me and my family are blessed to have found our go to mechanic. He also helped me find a better deal on eBay for the ac compressor I needed. I can't say enough about how good he is. read more

My MAINT REQ light came on while I was driving to San Diego this weekend. Alarmed, I pulled into Pep Boys to get my car checked out. They said my front struts needed desperate repair and gave me a 2-page list of other issues... totaling over $1,300. I decided to sleep on it. I found Tom/Quantum Mechanics through Yelp (thanks fellow reviewers!) and I am so thankful I went to him. I don't know much about cars, but he took the time to show me what was going on under the hood. No, I didn't need $1300 worth of repairs. I am truly impressed with his knowledge of cars, friendly personality, and honest practices. I HIGHLY recommend him if you're looking for a mechanic. read more

Tom was fantastic. Met with a seller at his shop to give it an inspection. Let me come in the day after I called, quickly had the truck in the shop to take a look at it. Made some great callouts and found a few things to get repaired. If this was my local shop, no doubt I would take it here. Absolutely take your vehicle here. You won't be disappointed. read more

Tom worked with me to find the cause of my check engine light so that I could pass the smog test. He was honest, trustworthy, budget friendly, and worked around my schedule. Hands down the best mechanic I have ever worked with. I never leave reviews, but I wanted to go out of my way to leave a good one for Quantum Mechanics. Excellent service by professionals that are great at what they do. read more

I own a BMW and I'm giving this spot a 5-star review... that should be all you need to know (inside Beemer joke), but I have more to say. Tom is a car lover's mechanic, he takes pride in his work and it shows. Thanks to him and his excellent, timely work, I haven't seen the inside of a BMW dealership in years. He does dealer-quality work, or better, at an affordable price. Most of the time, he can get OEM parts into the shop on the same day, which is great since I drive a ton for work. I have recommended his shop to numerous friends who all continue to trust him with any issues they have. If you need a new mechanic, Tom's your guy! read more

Quantum Mechanics - Auto Repair Near Me - Huntington Beach, California

Tom is great, he fixes all of my friends and family member's cars. He is very honest, has helped me above and beyond on saving money and is actually personable. I really appreciate his service and demeanor. In one instance he even pulled up an unknown warranty for me and saved me literally thousands of dollars. I will be going to Tom for many years to come. read more

Tom has been working on my car for the last 5 years and there is no way I would take it to another mechanic. Every job he completes is done with precision and he treats it as if it is his own personal car. Today, I went to his shop because my seat was not working properly and after just 5 minutes of being there he was able to correct the issue, he didn't charge me for his time, and in fact offered me a soda and water while I waited! So, it doesn't matter what kind of car you have or what problem you are having, I can say with a certainty, Tom will be able to remedy it at an affordable rate and in good timing. If you have found this gem of a shop than you are one lucky person. The days of taking your car to the shop over and over for the same issue and waiting days on end to hear what the diagnosis is are over!! Thank you so much, Tom! read more

Stay away from Tom and quantum mechanics. He does not care about your car. He will ruin your car just as he ruined mine and a bunch of other people's cars. If you care about your car I would avoid this shop and Tom at all costs!!! Tom put me through a nightmare and ruined a perfectly running BMW M3. He didn't do the timing right and bent SIX valves!!! Not only that he kept the car for almost six months!!! I took the car the day it was supposed to have been done and barely made it home. I had to bring it to another repair shop and they informed me of all sorts if things assembled incorrectly and incorrect and missing hardware. Missing parts!! Oil leaks! Coolant leaks! Many customers have pulled there cars out of there because of incompetent Tom. If you care about your car my advise to you is run away from this place. read more

While in Huntington Beach for an extended visit, I bought a truck to get around and drive back to the east coast. I was referred to Tom by a friend in the area, and called to set up a time for him to inspect the truck for a cross country trip. Tom was up front about his availability, and nothing but exceptional to talk with. We met at his shop, and Tom inspected the brake system, suspension, engine compartment, and frame. He notice the spare tire was almost totally deflated, so he filled it with air, and that I could do with replacing the engine's idler pulley and serpentine belt myself. He gave my truck a clean bill of health, and answered all my questions. Tom was super friendly, direct, honest, and overall a very refreshing and reassuring person to talk to about vehicles. Cannot recommend him enough. Thank you, Tom. read more

Great experience with Tom. He is very knowledgeable. Knows what he's talking about. I'm very happy with his work. My girl is happy and so am I. Basically he got everything done in a day. Evaluation repair and return. I'm going to recommend him to friends and family. Thank you again Tom. Richard S. read more

Tom is a great mechanic, he knows what he is doing and he explains everything in detail and take pictures and show it to his customers what work he has done on your car. Thanks Tom! read more

Absolutely 1000000% recommend this shop! I was driving down to Huntington Beach from up north and all of a sudden about an hour away my engine light came on and my car started shaking if I tried to go over 60mph I looked up some mechanics and called Tom and was hysterically crying because I had my daughter with me and didn't know what was happening and he was so nice and calmed me down and didn't charge me to figure out what was wrong and once he did he told me it was such a simple fix and didn't over charge me at all to fix it! read more

I don't usually write reviews on yelp, but sometimes you experience customer service that bears mentioning. Tom at Quantum Mechanics is an honest, helpful, and knowledgable guy. I really appreciated his frequent communication (via text) about the progress he was making on my car. He did all of the research to find affordable after-market parts, which created a good cost savings vs. going to the dealership. I felt like it was a trustworthy friend working on my car. If you're looking for a knowledgeable mechanic with a neighborhood feel, Tom is your guy. read more

Tom is the best! Came in to get a quick repair on a shattered side mirror and Tom not only did it for free, but had it done in less than 10 minutes. This is where I'm going for the rest of my auto repairs, thanks again Tom! read more

Tom is such a great guy! I'm going on a short notice road trip and I really needed my front brake pads replaced. He got me in one day and it only took about 30 minutes! Definitely the best mechanic I've ever been to and will be going to from now on. Super affordable too!! read more

I was told that I needed thousands of dollars worth of work on my car by several other shops in Huntington Beach. On my drive I found Quantum Mechanics. After stopping by and meeting Tom who was super personable and honest, he told me I didn't need half of the things other places told me, they were all trying to up-sell me. After he diagnosed my car and gave me the price I decided to get the job done (minor tune up with a motor mount). My car runs amazing and feels like a brand new car. When it comes to getting automotive work done, it sucks being a woman, because mechanics think they can rip you off! I am so happy I found Tom @ Quantum Mechanics, not only was he honest and trust worthy but professional as well! Ladies and Gentlemen if you need great, honest work I recommend Quantum Mechanics! read more

I've had two repairs with Tom. Completely honest, excellent work and on-time. Never going to a Mercedes shop again - only Quantum. You will not be disappointed. read more

Tom took care of everything I needed for my Corolla and well below what I would have paid at the dealership. He's very friendly and since I have no understanding of cars aside from how to turn it on, he spoke to me in a way that clicked, with no condescension. The work I had completed was: front brakes and rotors replaced, spark plugs, oil change and filter. All that for under half what the dealership would charge. I will definitely be back. read more

The best workshop for your car and friendly guys right there I met there today Tom Huerta it's a great respectful man

Same day turn around for my 40,000 mile tune up. Another mechanic wanted to charge me hundreds of dollars and Tom saved me over 50%. I am extremely grateful and now a lifetime customer. I can't recommend him highly enough. Definitely your 'go to' mechanic. I will be sending all of my friends/family to Quantum. read more

Tom has saved me SO much money. I was referred to him from another trusted family friend mechanic when I got a new car. He is honest and will fix what actually needs to be fixed with your car. In the past, I went to him for a couple of minor fixes. More recently however, I went to get only an oil change at Meineke and they then recommended that I replace several expensive parts of my car totally almost $3,000 in parts and labor!!! I went to Tom to have him take a look because I wanted a second opinion. After inspecting, he said 90% of their recommendation was BS and there were only a few small things that need to be replaced (an air cabin filter, spark plugs, ect.) He recommended in six months I get another smaller part replaced. I spent $260 on some needed maintenance as opposed to throwing away almost 3grand. He also showed me the website https://www.driverside.com/ so that I could find out on my own when certain parts need to be replaced on my car and what a standard rate on different parts are, that way I can prevent getting BS'd from other mechanics trying to scam me. He has worked on my boyfriend's car for a couple of years and also saved him a lot of money in repair cost. He's super personable, honest, and timely and does a great job. He's everything you'd want in a mechanic. read more

Everybody is always saying that they need a good mechanic at a reasonable price. Well, look no further than Tom the owner of quantum mechanics.Tom did a great job in installing performance parts and my 2018 AMG E63 Mercedes. He kept me up-to-date the whole time. He promised to get me my car back by Friday. When, at no fault on the part of Tom, the parts did not arrive until 4 o'clock on Friday afternoon he stayed until after 10 PM that night to get my car done as he promised. Tom did a great job on the installation and charged a very reasonable price. Great work at a reasonable price. I highly recommend Tom with quantum mechanics. read more

Please allow me to start off by saying that I'm probably the pickiest person around. Yes, it causes much stress in my life because I'm never happy with products and services doled out these days. Oh well, my issue! So, to the point ... Tom is absolutely the best!! My clutch went out in my 2008 Audi A4. After some price shopping and going through many reviews of other mechanics, my neighbour recommended Tom. Not only is Tom a super sweet and kind man, he is honest, ethical and reliable. He gave me the best price and provided the best job. What more could you ask for? Tom takes great pride in his work and therefore, he puts in a lot of love and attention into every job. My clutch works great now, and it was done with perfection. When I picked up my Audi, he showed me the old clutch and explained the issues. He is definitely very knowledgeable. I will be returning to Tom for all my service and mechanical needs. Trust me on this one, you will be very happy with Tom! read more
