Jason is awesome. He arrived on time and he was super chill with me watching what he was doing because I was interested (he even explained what he was doing). The repair was a super simple repair and it was done quickly. He even helped me set up these remote fobs for my car that I bought online. Super cool guy! Definitely recommend booking him!!!

I couldn't have asked for a better YourMechanic experience. Jason was extremely knowledgeable and helpful in diagnosing and fixing the issue with my car. I would trust Jason with my car any day. A really nice guy, and a great mechanic. Should I have another issue with my car, I would definitely want Jason to work on it.

This Timing belt and spark plug replacement for a Mitsubishi V6 SUV is a hard job. Jason knew what he was doing and was methodical and deliberate. He also has the experience with the newer pollution plumbing that was in the engine bay. Very professional, fully equipped and patient. Things can go wrong with tough jobs and a mechanic with little or no patience can get sloppy. Jason was not so the tough job was done well. To future customers: If the mechanic is going to be on the job for a while (and you feel like he's a decent person), offer snacks, a small meal, something to drink. It just establishes goodwill between you and the mechanic. Treat them well and hopefully, they reciprocate by doing the best they can for you.

I have had Jason work on my car several times, he is always soft-spoken courteous honest and reliable. He only suggests what is needed for my car to run optimally and never tries to over- sell. I recommend Jason to everyone I know with a car. I am very pleased with Your Mechanic and the mechanics they employ.

on March 16

Jason is knowledgable, reliable and friendly person. He took his time to explain things about my car. I highly recommend YourMechanic and Jason's service.

on October 15

Jason was extremely professional. He is very good explaining everything. Jason went above and beyond the service and 1) Cleaned the fogged residue on the cars headlamp and 2) check into a noise the car was making and isolated it to right strut. Esp after i mentioned that I just bought this car after getting pre-purchase inspection through YourMechanic. Jason acknowledged that issue should have been caught in the pre purchase inspection. I would be happy to use Jason again.

on March 12

Jason was extremely knowledgeable about my car and also very friendly. This was my first time using My Mechanic and I will definitely be using them again and make sure I ask for Jason and I'm going to tell all my friends & family!

Very impressed with his technology. When I peaked on him, I noticed he was using a laptop to do a diagnostic. He informed me that my Camshaft Adjuster Solenoid needed to be replaced. He offered to pick up the part and fix it that day. I was impressed that he was willing to drive out of his way to fix my car. He completed both jobs in a timely manner. My check engine light is no longer on and my car drives like it's brand new! I am very happy with his work and will recommend him to everyone I now.

on March 10

Jason is the man! He is friendly, polite and professional. And he knows 4Runners. He was patient with me while I asked lots of questions about what he was doing along with other maintenance questions not related to the valve cover gasket replacement. I highly recommend him.



Audi TT
on May 09

Car - Audi TT Sports; YourMechanic/ Jason Certeza I have taken the services of YourMechnic multiple times, and have always been very happy about it. in 2015, Yourmechanic, worked on changing my timing belt, starter replacement and serving. They also took care of my yearly servicing. In 2016, YourMechanic took care of powersteering sensor replacement and yearly servicing. Jason Certeza has worked multiple times with my car. This appointment was wrt to some squeaking noises from the power steering. He inspected the car, and quickly found the sensor to be defective. We went ahead to order the part, and Jason would fix it in the next appointment. Jason has deep mechanical knowledge of car(mine is European). He diagnoses, the problems very accurately, and explains very well. Jason also goes the extra mile, helping to buy the correct item. All in all, i would recommend him very highly, and would reach out to him for further repairs.

on March 19

Jason did an excellent job on the oil change. He came to my place of work which is incredibly convenient! He topped off some other fluids and also notified me of some issues that could trouble me in the future. I highly recommend Jason and YourMechanic!

on March 09

It's so nice to have someone near our place and work on the car. Jason has a great attitude. I only here for the oil change, he fixed my car's leaking problems with no charge as well. Since Jason has a great service, we were already schedule the next appointment for brake pads replacement. My family and I will recommend Jason to our friends.

on March 19

"Seeing is believing". I truly appreciate doing business with YourMechanic whom would go extra miles in cutting cost and yet providing huge $$$ savings to the customers. Positively, I will do business with YourMechanic again and again in the future.

on August 12

Jason did a great job replacing new front lower control arms (with bushings already installed on them) on my 2006 Scion Xb. Very methodical and knows the ins-n-outs of various vehicles. I will be using Jason for my other vehicles as well, as their maintenance and fix-it schedules come about.

on March 23

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 March 23

Overall I'm satisfied with the service. I think the only issue I had was that Jason mentioned that he didnt have all the parts to do my oil change. He had mentioned that there was some schedule mix up and that he was not even supposed to be there.



Chrysler Town & Country
on February 26

Jason arrived early. After time, he discovered the reason for my squeaky wheel (a defective rotor from O'Reilly Auto Parts). I was happy with his persistence in diagnosing the problem, making sure to find the issue correctly without giving up. He even took time to explain some other things about my van. The only thing that I did not like was how long it took him to get the new rotors from the store (took about 45-60 mins).

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!

Jason was great. I have already recommended him to a friend. He showed up right on time and wonders of wonders, told me there were some things that I'd thought I needed but weren't really needed at all! So he did everything necessary and my bill was less than I'd thought. Thank you Jason! The truck is stopping just great now, and I'll call you next time I need more work done. 5 stars!

Jason Made Sure I Knew What was going on with my car, most mechanics don't explain they just tell you what's wrong he walked me through the process and explained step by step why each procedure he does is important. Very friendly, takes his time, and makes sure you as a customer is satisfied with his work and if there isn't anything that you don't understand he will gladly walk you back through the process. I would definitely be using his services again in case there is another problem. Thank you so much Jason you did a great job dude!
