Tom is excellent. He is able to diagnosis issues in an hour that would take half a day at the shop. He is very good at communicating his diagnosis and recommending exactly what is needed and nothing else.

on October 25

Tom was extremely knowledgeable, helpful and honest. He took the time to walk me through his troubleshooting process to help me feel comfortable with the repair options and also learn a few things along the way. He went out of his way to make sure i was satisfied and my car was working.

on October 20

Tom is an awesome guy! Even though my car started right up when he got there, he did a full diagnostic on my car and made me feel much more comfortable and now I know exactly what my car is doing! His personality is amazing!

on January 21

Tom was absolutely fantastic. When you're buying a used car is easy to feel vulnerable. Because of Tom's inspection I was able to feel confident I was making the right choice. I would totally use Tom again. Thanks, Tom!

on October 25

Tom was friendly and professional. I was a few minutes late getting home, but he was very understanding and got straight to work as soon as I arrived. He did a great job with the oil change and left my driveway just as it was when he arrived. I loved the convenience of having him come to our house and will definitely be using YourMechanic again!

on August 11

Tom was very professional and thorough with his work. I am very pleased with the work he has done on my car and plan to use his services. I will also recommend his services to colleagues looking for a good mechanic.



BMW 545i

Tom came to replace my rear wheel bearing on my bmw, thought it would be somewhat of a easy job, but let me tell you it was a major pain, the hub was ceased onto the bearing and the rear axle was kind of stuck on the hub, let me tell you tom was amazing, the was suppose to be about 1.7 hours, I think he was there about 5hrs and determined to repair my car. Tom was great and will definitely use him again.

on June 09

Tom was there to do a oil change but I picked his brain on other car issues and thought he was very knowledgeable and professional. I would definitely use Tom again!

on May 27

Tom is the 'Real Deal'. Not only is he an expert mechanic that you can trust, but he also provides excellent service. His business model is great because he comes to your house and gets the job done. No more guessing with your mechanic or getting a ride to the shop and leaving your car there over the weekend! Also, the prices are very fair and reasonable.

Mr. Gaynor's service was beyond my expectation. He was courteous, very knowledgable, neat, very, very thorough, explained every detail...would rate 6 stars if possible. I would not hesitate using this service again.

on June 06

It's a great experience to use the service from YourMechanic and Tom Gaynor. Tom is definitely a mechanic and person I would like to work with again and recommend to anyone else.

on June 09

Tom was very professional and courteous. Very satisfied with the service he provided. He has a very good understanding of all the parts in the vehicle. It's a 5/5 for me but with the caveat that goes to a lot of mechanics (including Whitney): They generally assume that the customer doesn't know anything about the working parts in the car, and answer the queries with a defensive, passive-aggressive tone which can be annoying. Perhaps that is result of the customers they meet. I felt that way, and had to stop him by saying that I am a physicist (and have experience working with thermocouples, pumps and other mechanical parts)- which obviously, I don't like to do.

Volvo 850

1. YourMechanic rescheduled my appointment because the parts were not available in time. That should have been determined before scheduling. 2. Wrong parts ordered and given to mechanic. Result: Couldn't fix bad motor mounts without rescheduling for a 3rd time.



Honda Civic
on October 18

Tom was able to quickly diagnose and fix the problem (bad alternator) while also taking the time to explain what he was doing. He was friendly and professional. Would highly recommend.



Ford Mustang
on October 12

Knowledgeable, friendly and goes above and beyond to explain the problem to a layman and talk through possible solutions pros and cons. Will give you tips that you would not otherwise get over the counter at the dealer or a shop.

Tom was supposed to arrive at 11am but he called me at 10 to let me know that he wasn't feeling well but would be able to come at 1230pm. He did arrive promptly on time and was very friendly and courteous. I would definitely recommend him to others for their Uber inspection.



BMW 325i
on January 11

Very happy with my experience with YourMechanic and my mechanic Tom. The company kept me updated on my appointment and fees and Tom was friendly, did the work professionally and answered all my questions.



on September 01

Tom was there on time and completed the work as quoted. Very friendly and knowledgeable, and was able to come on a Sunday which was extremely convenient. I will recommend Tom to friends and neighbors.

on September 27

Tom was clear in calling out the issues with my vehicle. He gave practical guidance on items needing immediate repair versus those needing monitoring for a follow on service. He was punctual and got the job done on time as promised.



Nissan Murano
on September 20

Tom arrived on time for the service appointment to service my rear brakes. He was courteous and completed the work efficiently and did an excellent job. He seemed very knowledgeable about auto repairs and seemed to care about the work he did and the satisfaction for his customers.

on September 13

I got replace ignition coil and spark plug on BMW 328i 2011 model, It was very good experience with Tom, he knows well about BMW and does the job nicely. But on your mechanic did give the $20 credit for the first time use as last time I had just contacted your mechanic.

on September 08

Tom was very thorough and he explains every step of the diagnostic process to me. I don't know much about car but listening to him I can sense that he's very knowledgeable and definitely know what he was doing. Looking forward to get my car fixed this Saturday.

Audi A4 Quattro

I got a good experience with Tom. He inspected the brakes and tested my car before doing the oil change. He suggested me only need to change the front brake pads at the next appointment. This saves me money. I really appreciate his service.

on June 08

Tom was very helpful and very knowledgable in VW and made sure that I understood what was going on with my Jetta. I had a lot of annoying questions, but he was pretty patient in hearing me out about my concerns and didn't judge me on the current conditions of my car despite it surviving my college years. He also gave me some advice on how to better care for my car in which I will definitely take! He will probably be my go-to VW guy since I have a second vehicle.

on June 09

Tom was very personable and enjoyable to work with. Right when he arrived, I felt completely at ease with him. He was very professional and knowledgeable. The problem I had with the car didn't show up when he was here but he looked at all the possibilities and found the car to be in generally good shape and made some recommendations of what might have been the issue. Additionally he found my rear brakes to be in desperate need of replacement. I scheduled an appointment for him to come out at a later date to repair them and look forward to his visit! I will continue to request Tom to work on all my cars.

on July 08

As usual, Tom was professional and very personable. He is very knowledgeable and easy to work with. I will continue to have Tom work on all my cars. I'm very happy with his service!

on June 17

This is the first time I have used Your Mechanic and I am impressed. Tom had all of the diagnostic tools at hand and quickly found the fault. Repairs and parts were not required, simply a reset. Before he left, he did a thorough once-over of the brake pads, engine compartment, oil level, tire air pressure, and checked for leaks. Tom is a very personable guy...

on November 01

Tom is awesome. Very friendly, professional, and completed the job very quickly. I just took my car out for a spin and it's running nicely. Thanks again Tom!



Mazda RX-8
on August 21

Tom was great. He was on time (even calling ahead to let me know he was on the way), came with all the proper tools to do the inspection he needed to do, double-checked both the battery and the alternator, and my car is now charged up and happy. He was just pleasant to work with, clearly knew what he was doing, and was knowledgeable about the car. I would happily pay for his services again!
