Nice guy!

on November 07

Jason can do the work very quick. The knowledge he has as a mechanic is very insightful. It's good to know what cars use in their technologies and Jason will tell you what's happening. He cares about the service being worked on and I would recommend most customers to give him a call with YourMechanic. He noticed a crack in my reservoir when I bought a used car. I had some JB weld and he put on a couple coats after using a tool to find the damage. Nobody wants to run into an extra problem like that. So that's a real good guy. Thanks!

Great and technically difgicult job he stuck in there way into the darkness to complete. Really nice job. Couldn't be more pleased.

Jason was great and took the time to ensure that the work he did was done with quality and care. I highly recommend him!

on August 31

Jason was thorough and made sure I was aware of the status of my vehicle was and my options. He is personable and polite. He worked quickly and before I knew it, Jason had completed the required work and asked permission before road testing his work. He then took the time to review what work had been done. This is the second time Jason has done work on my family's vehicles. I would and WILL recommend Jason's services to friends and family.

This was a pleasant YourMechanic experience, with Jason C. doing the job for my toyota sienna. He is honest and reasonable, recommending what is best for your car according to its situation. Instead of just doing the work order which if unnecessary will be a waste of money, he did preliminary inspection and validated what actual work is (or may be) needed. The problem with my car's VSC was kind of tricky, but he spent extra time to figure it out and get solved. Awesome job!

I am extremely impressed with MyMechanic and Jason. I am driving to Tahoe this weekend and Jason assured me that all is in good working order...just need to put air in the tire!! Once I am back from Tahoe, I will definitely recommend your service! Best of luck!

on August 16

Jason arrived exactly on time, diagnosed the issue, which wasn't what we thought it was. So he saved us paying for unnecessary work, unlike other less reputable places we've been to in the past. He kept us informed the whole way through. Will definitely use Jason again, and would recommend him to anyone! Thanks!

Jason showed up within the scheduled time. He explained the process and everything that he was going to be doing. They shipped him the wrong brake rotors, but he went straight to O'Reilly's and got the correct ones. After he finished the job he explained the diagnosis he performed, the service, and how I was going to be billed. He was very professional and friendly.

Jason was here to inspect my car this evening. He was very patient and extremely responsible, He explained to me as he worked on my car, and made sure that I understand everything. He also gave me some useful tips and suggestions on how to take proper care of my car. I would highly recommend him to anyone who need service done.

on October 18

My 1993 Acura had been in desperate need for an oil change, and I have been totally dragging my feet, despite knowing better. On the evening of my appointment, Jason called me around 6:45PM, telling me that he was in the Blossom Hill area and would be a bit tardy getting to me. Sure enough, he arrived at my designated location promptly after that, and started with my vehicle. Jason was incredibly thorough, examined everything, communicated to me everything he found, and took care of the scheduled oil and filter change like a pro. Turns out that I'm gonna be in the market for a new water pump: Guess who I'm gonna book to fix it once I save up the amount? =)

I have had great success with Your Mechanic. I love the service, professionalism, online communication is great, easy, and best of all a great value compared with going to a shop. thanks again! Russ

Jason is a professional and he was patience with my questions. I felt confident that he can perform more jobs on my bmw when I need him to. I would recommend Jason to anybody who needs their car service done.

on February 25

Jason was professional, prompt, broke things to me in laymen's terms and gave me an honest assessment of what service my car would need both short term and long term. Nice and honest guy, which is quite refreshing for a mechanic!

on November 18

Jason was a mega blessing to me . I really appreciate how he got my vehicle up ,and running. How he tested my vehicle, and made sure that it was safe. I was very pleased, with his job performance. I would recommend, him to anyone. Excellent service!

Incredible. Nicest guy and took the time to explain everything that was going on to me. He even saved me some money on duplicate parts that were ordered automatically through the quote. Now that's someone I can trust. Super friendly, came on time and even called me the day before so he could be prepared.

on July 10

He was on time. He let me watch and educated me about the systems as he worked on them. He even helped me diagnose potential other problems for future servicing. Simply amazing. Respectful, friendly, trustworthy and incredibly knowledgeable. There is nothing more you can ask for in a mechanic.

on July 07

Was very thorough in a pre-purchase investigation. Being an out of state purchase, I was much more comfortable with the process after he reviewed the car and presented any potential issues. Very communicative as well.

on July 26

Jason was great, he actually took off $200 from our estimate as some of at any dealership, they would have found ways to charge unlimited $ more and still not be fully done.. these guys are just good, the car stays at your house, you know they are working on nothing but your vehicle and they explain everything in "plain english"...

Jason Certeza is probably one of the best if not the best professional mechanic I've met. He's honest, thorough, communicates well. He fixed and went beyond to explain/answer patiently all my questions. He's one of a kind, and he does not take advantage of the customer's ignorance. Thanks for sending him to fix my son's Honda Civic. You've gained a customer for life.To YourMechanic, please put on the website that he's ASE Certified....thanks again

This is the 2nd time I've tried Your Mechanic and so far I have been very pleased. Jason was very thorough and took the time to explain everything to me and help where needed. He updated me to what I may need next and to keep on eye on it. No pressure and very accommodating. Spoke about issues on our other car and will be looking to now have that serviced through this company too. Jason was extremely helpful. Enjoyed this service!

on November 06

I'm fairly unfamiliar in the area of car repair and this was my first time with yourmechanic. I got Jason, who did a great job in explaining what to look for and where my car might be having issues. He did a terrific job in the oil and filter change and servicing and I couldn't be more satisfied!

Most mechanics would just install the starter I provided. Jason took the time to test the starter in my car and explained how it all woks. He did the job effortlessly, at night, with a flashlight in his hand! I will definitely recommend Jason to my friends and family.

on February 02

Jason was great to work with. He explained everything and showed me what he was working on. Great communication and very knowledgeable. I will be requesting Jason again to do future work.

Jason is an incredible asset to 'Your Mechanic". Be good to him, he is a keeper! He was working in the rain, came prepared, had a tent to cover car so he could work. He is unflappable. He perseveres till the job is done. I am certainly recommending 'your mechanic to friends'. Keep up the good work, it will be rewarded. Jason is A++++. Thank you Jason.

on December 17

Jason went out of his way to fix my car and got it up in running in a quick and quality manner. He has a great understanding of automobiles and has a strong work ethic. Overall he is honest, thorough and professional. I would highly recommend Jason to service your car. Thank you, Jason

on December 15

He's very honest and reliable. I've never had such good service in my life! He was very friendly and nice going above and beyond the call of duty to do everything that needed to be done for my car. My car is now running as smooth as when I first bought her.

It was my first time using Your Mechanics and it won’t be the last because of Jason’s excellent service. Jason called me before the visit to recommend using a different brand of spark plugs to save a decent chunk of money (ngk vs denco). During his visit, I was in and out of the garage but while, Jason clearly explained what he was doing. Definitely not for everyone but I rather enjoyed learning about my own car instead of being completely in the dark during regular garage visits. There was a quirk in how my car readjusts idle control after the spark plugs are changed. Jason stuck around for an extra hour until he figured it out (answer: disconnect battery for 10min). I felt comfortable through out the process. Highly recommend Jason.
