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!!!

Jason was amazing and was able to correctly diagnose my car problems (which multiple other mechanics could not do)! He is timely and professional, and took his time to fix all the car's problems.

Had yet another great appointment with Jason. This time was a simpler task, 65K mile spark plug swap on my Mazdaspeed3. Not a big job, but it went well. Got some ideas of other things to tackle later on.

This is the 2nd time Jason has come to help with my car. First was a routine service, and 2nd time was to fix an issue he had identified during the service. Jason was punctual and prepared with the tools and parts needed. He showed me the issue he had found; explained what was happening and walked me through the steps one by one. He made a recommendation about an issue to be fixed, but he wasn't pushy, which I appreciated (as a matter of fact, it took me 4 months to book the follow-up appointment).

Jason exceeded my expectations and delivered a highly professional, courteous and efficient service. I would definitely use Your Mechanic next time we need help. Highly recommended.

on December 05

Jason has come out to service my car twice. Both times he has shared knowledge and shown me how to fix my vehicle. But lets be honest here. As long as Jason is around I'm not picking up a wrench. I'll continue to use Jason as my mechanic.

on December 02

Jason did an outstanding job replacing the valve cover gasket (5-6 hour job) on my BMW328I . He knew the parts , had the tools and knew how to take it apart and put it all back together.

I have met a lot of mechanics in my time, several of whom stand out in my mind but after two appointments with him, Jason Certeza is now at the top of my list. I found him to be an excellent diagnostician, with a wonderful manner about him. Because of my experience so far, I have begun to spread the word about Jason as well as service at YourMechanic.com. I am sold.

Jason was very knowledgeable and deliberate. He did an inspection to verify the complicated problem and the proceeded to acquire the OEM part required and credited me the inspection fee as he completed the repair. I would highly recommend Jason on all types of repairs and service.

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 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.

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.

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.

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.

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!
