Isais was very informative and patient with all my questions

on November 01

Isai was timely and communicated well with me. He explained what he was going to do and showed me the new part. When he was finished he contacted me and showed me the completed working door handle. I will use him again.

Excellent work. An honest mechanic that gets the job done correctly and explains everything in great detail. Thanks Isai...

on October 24

I said was prompt, very very professional and extremely informative. He made sure I understood everything he had done before he departed. If I need maintenance on my car in the future, I will be requesting him.

on October 20

He was early for the appointment. Very knowledgeable. Provided exactly the info I needed. Provided me with prices on additional work. Left me feeling at ease about my car. Amazing mechanic.

on October 18

Isai called to say he was available earlier than planned. Worked out very well. He replaced the started and explained the difference between the parts he gets and the parts that are sold in auto stores. I'm very glad that he was the mechanic that was assigned to my van. I will use Isai every time.

on October 13

Very helpful and very nice. He fixed my heater hose as it had broken open on my Chevy Aveo. I hope I don't have any more issues for a while but, if I do I want Isai to work on my car.

Isais was very professional and courteous. I found out after he arrived that the work would not be warranted due to me supplying the parts. I knew the parts I had purchased were of good quality and that Isais's ability to do the job would be sufficient to do the work without a warranty. I was very happy with the work he accomplished.

Mr. Rodriquez did a careful inspection and diagnosed the problems with my 2004 GMC Sierra's AC and right turn signal. I booked the appointment online and was notified by Your Mechanic of the appointment and some suggestions to make the appointment go smoother. Mr. Rodriquez was on time and completed the work in a careful and prompt fashion. My AC and right turn signal are working wonderfully and I'm very happy with the expertise, professionalism, and time to complete the repair.

Isai was able to arrive a little earlier than scheduled which was great. My car is an older car and it uses a carburetor not fuel injection. Finding a mechanic that knows how to work on a car with a carburetor can be a real challenge. I found Isai to be very knowledgeable and through. He answered all my many questions. He is very friendly. I certainly would use him in the future.

on September 20

Isai was punctual and very thorough. Although the issue he discovered with my vehicle could not be taken care of at the time, Isai guided me through my best options that would be most cost-effective and beneficial to me and my family. Do not hesitate to book Isai. He is straight forward and efficient! I will be using him again!

on September 15

Isai showed up on time, he was very patient and friendly. He is competent and he's good at explaining things to you and make it easy for you to understand. It was definitely a pleasant experience and I will recommend him and this company for sure to my friends and coworkers.

Great diagnosis! Being able to trust someone to repair my daughter's car when I am a 1000 miles away is priceless. Kudos to "Your Mechanic and Isai " for a job well done. I highly recommend "Your Mechanic" for anyone looking for trustworthy affordable car repair!

Mr. Rodriguez was able to arrive earlier due to a cancellation. He was knowledgeable, pleasant and explained what he was checking on the vehicle and why. After checking out things, the issue is spark plugs. He also explained that my vehicle does not have spark plug wires. Which I thought it had. If I had taken my vehicle to anyone else and asked that the wires be replaced also. who knows I may of been charged for replacement of wires, without ever knowing that my Nissan does not have spark plug wires. I am so grateful for Mr. Rodriguez he is excellent.. So glad I found your company online, and for having excellent, pleasant, knowledgeable mechanics as Mr Rodriguez. I have booked the appointment to have plugs replaced, had to with another of your mechanics. due to Mr. Rodriguez's' schedule booked until sometime after July 7th. and need to use my car before that date. Otherwise I would wait and book Mr. Rodriguez to do the work, but I am sure all your mechanics are just as capable and pleasant as Mr. Rodriguez. I will certainly book Mr. Rodriguez to help with any other problems that arise with my vehicle and recommend your company and him to all family and friends. I thank you all for having such a great company and employees. Think this is the first time I have been happy to spend the money needed to repair my vehicle and have been made to feel as if I am dealing with a trusted friend. Thank you....

Isai is fantastic, I actually had him come by the day before to change out a Crankshaft Sensor but had a couple other questions in regards to other issues I'd been having with the car. He recommended that my drive belt needed to be changed and took the time to show me the cracks and obvious missing pieces in the belt that I had. For about 2-3 years the dealer had told me that the reason my belt was noisy was a faulty alternator clutch, after working with Isai, I'm pretty confident that the dealer just didn't know what they were doing. I would recommend him and YM to anyone.

on November 22

Isai was fantastic. He was able to show up much earlier than what was available online. He finished the job in short order and was able to explain and show me other potential issues with my car.

on September 08

Isai was great. He was punctual and very polite. He fixed the problem and explained a few things about the car. I would for sure recommend him to a friend!

on November 22

Im very new to using YourMechanic services but couldn't be happier! He was very professional and educational. He took the time to explain to me the issue i was having with my car and made sure i understood. At the end of my appointment, i walked away with full confidence that i was given true and expert advice on what i need tk do next for my car needs.

on December 08

It was the first time I used this service. I have to admit I was skeptical when I booked. Isai called prior to the appointment to let me know he was on his way. He was on time and professional. Will definitely use the service again. Easy.

on December 12

Isai was awesome: communicative, professional, courteous, and on top of everything we needed him to be for a pre-purchase vehicle inspection. Everyone I know needing service will hear about my experience with Isai from Your Mechanic. Many thanks.

on November 17

Isai was great! He came by, explained how the whole process worked and completed a fast/efficient job. I will definitely be using this company much more, as well as this specific contractor. Thanks Isai!

Isai was very helpful in diagnosing that what I had ordered was not the actual problem. He explained what was wrong with my vehicle and instructed me what to next.

on November 03

Isai was fantastic and very professional. Will use exclusively for all my future YourMechanic bookings. I booked hours before he came, and there were no issues on such short notice. I had an alternator replaced and it was done within an hour.

on May 01

Isai was absolutely wonderful. Very professional and knowledgeable. He was able to answer questions I had in addition to my simple oil change for other issues I was having. Definitely want to use YourMechanic again.

He was very helpful and honest regarding what repairs were needed and advised how I should proceed. Very happy with both his professionalism and demeanor.

on April 03

Isai took his time to explain some basic information that no one had ever taken the time to. I am very appreciative for his professionalism. Many times as a female customer I have felt taken advantage of simply because of a lack of knowledge of cars. Isai empowered me with basic info and I will absolutely recommend him to my friends in the future. Thank you.

on January 29

I was absolutely delighted by the standard of service we received. Not only will we be long time customers but we will wholeheartedly recommend this service to family and friends.
