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.

As usual, did a great job on my belt change. after 160,000 miles, the belt was squeaking and cracked. Not any more.

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).


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.

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.

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.

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 was very professional ,called and let me know when he was arriving, and the job was done in a timely manner. Thanks" Your Mechanic" your service is truly needed and appreciated .

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 October 03

Jason is hands-down the best SAE certified tech out there. His troubleshooting skills, patience, and experience are bar-none the best and I am a "car guy". He doesn't overlook anything, is meticulous as to how to eliminate both electrical and mechanical parts to get to the root of the problem, uses current technology well for aiding in the repair and goes above and beyond the call of duty to satisfy the customer. He repaired a Mercedes 722.6 5 speed automatic transmission in my 2005 Crossfire SRT6 and ensured that it operated correctly. The common problems were discussed ahead of time as both he and I did the research based on the speed-sensor codes and symptoms it was displaying. The "conductor plate" within the transmission body was suspected and confirmed as faulty through exterior testing. After replacement of this part containing the transmission speed sensor, the car ran fine again, and will be tested by me during the upcoming weeks. Two thumbs up for Jason. He's a valuable asset to YourMechanic.com and I will have him do other work on my other sports cars as he knows his stuff and has sports car experience, even with off-brands like the Mercedes clone Crossfire.


on August 09

Jason is very professional and walked me through the details of oil change and inspection. He also gave me few tips on hybrid battery performance and maintenance. He thoroughly checked engine, coolant levels, oil leaks and tyre pressure to make sure everything is good. I really don't want to go to dealers any more and I am very happy with the service and strongly recommend him to my friends.


on September 07

Jason did a great job in finding out what was wrong with my car and communicating it to myself and my previous mechanic. I will not be using my previous mechanic for any more services and I'm looking forward to Jason repairing my car on Friday September 10,2015.


on August 09

Jason was prompt and called me prior to his arrival. He was very professional and exhibited a workman like competency throughout the repair. I am very happy with the result, and I saved a substantial amount versus the dealer quote I was given. I will definitely use Jason for future repairs and servicing, and will enthusiastically recommend him to my friends and family. A real find!

Yourmechanic helped fixed a couple of issues in my car. There was a crank sensor issue, and Jason C fixed it very well. He took time, and diagnosed the problem very well, and then did a wonderful job, setting the car right.

Jason has replaced my dead battery, he knew everything that needed to be done and made also a general check of my vehicle to make sure nothing else went wrong. He researched common problems of my vehicle make related to battery exchange online and made sure I don't have any of them before he was satisfied with the work. Very friendly and professional.


on September 07

Highly knowledgeable and a skilled worker. We had a long chat about car stuff and I learned a lot of new things from him. Would recommend without hesitation.


on September 24

Jason was on time and very professional, he adapted well on the first visit based on a change in the order he rescheduled with the new parts as I requested and the final price for the work came in under the original quote the first work eliminated 99% of the rattling in the front but Jason wasn't satisfied and came back to troubleshoot the issue that remained and Identified that there was another issue . he proceed to get me an affordable repair quote that was within the budget I had set for fixing my front suspension issues

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!

Jason did a first rate job. He got right to work, knew exactly how to correct the problem and had the correct replacement starter with him. The whole process took slightly over 1 hour. This was my first experience with My Mechanic and it was excellent thanks to Jason's professionalism.


on August 28

Jason is Amazing. He always gives me the full description of what is wrong and what he is going to do to fix my issues. His work is GREAT!! and he always leaves my cars cleaner then when he started working. I would recommend Jason to anyone. Great customer service.


on October 04

Jason it great. He isn't bothered when I ask my many questions, trying to understand the repairs (so I don't get ripped off). He makes sure to put down a tarp so that fluids don't spill in my driveway. Not all their mechanics do that.


on September 30

Jason was great ...he was able to pinpoint the additional issue with my front suspension and completely and effectively fix the problem and the total was well within my established budget


on September 14

Jason is professional and courteous, he is prompt and efficient, I specifically ask for Jason though I will have to settle for others and pray they are as knowledgeable
