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 did an excellent job on my 2007 Pacifica for oil change, coolant flush, thermostat and radiator cap replacement. He kept my garage and driveway clean.

Jason was professional, curtious, and did an amazing job. I feel he went over and above what I request him to do. I will request Jason anytime I need an honest mechanic.

Great mechanic. Very thorough and knowledgable about how circuits work and sensors systems. He explained everything that was going on with my car and only replaced the parts that were actually needed. Very happy with a job well done. Highly recommend!

on October 24

Jason did a fantastic job, and even suggested waiting to replace parts rather than push me to go forward with services I didn't currently need.

on November 19

He knows what hes doing. I made appointment for brake pads but he didnt recommanded it cause they still have some lifes left.

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.

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 November 23

Jason, was very professional had to come back because I needed disc's replaced. He took longer than I expected and my brakes are still not right.

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

I was pleasantly surprised how smooth this process went. This was my first time using MyMechanic; although I was somewhat apprehensive; I thought it was a great idea and the repair quote was very competitive. I liked the idea of having the repairs done at my home. Jason did a great job and even recommended some things that save me money from the original quote. The replacement radiator was new and the job completed in a little over an hour. Jason was so professional and efficient and let my place very neat.

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.

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

on September 14

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.

This was another top quality job by Jason and I was grateful that he was able to get me in when he did.

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 August 21

Jason was very courteous and professional. He answered all my questions and offered top notch advice! I would highly give him two thumbs up for his work ethic.

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.

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!

GENUINE HONEST MECHANIC! Jason's pre-purchase inspection of my 2003 Jeep Liberty was outstanding! Not only did he give his thoughts on the car, but he allowed me to observe what he did every step of the way. Jason was professional, down to Earth, and knowledgeable. If you get Jason booked, you won't be disappointed!.

on September 05

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.

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 September 13

Jason really came through at the last minute and worked late through the night. He helped diagnose a few problems I had and explained what he was doing. I'll definitely schedule him for a few other things I'd like fixed in the future. Thanks!

on June 17

Jason did a great job. He was not in a rush and took lots of time to answer my questions, so I could understand what he was doing. Even though I don't need to now every detail, it helps me to hear his reasoning and logic for the repairs to see if they are consistent from what I have learned in the past.
