Would eventually get cool but after maybe about 15-20 min. Finally brought it here. Was expecting them to say, I have to leave it for a diagnosis. No. I called and asked if they provided A/c service about 11 a.m. they said yes. Can I bring it today? Yes. Brought it in and was real skeptical because he just sounded way too sure what it was after I explained my issue and figured it had to be something more complicated. He even gave me a time it would probably be done. My head said, "he hasn't even looked at it yet" sure enough 4:00 came a call came and said it's ready. Walked a few blocks to pick it up. No bad news. Did exactly what he said and it works. This is the 3rd place after 5 yrs. I don't have a lot of time as we work a lot to take the time for car service. This place came through. First experience was spot on. I would recommend them. My wife was super happy. She sent me a text the next morning excited. I shared in a picture.

Armen responded fairly quickly with the price for the smog, no games or special hoops to just through, thank you very much. Price seemed right for a smog check and cert. and I liked how he was straight forward and helpful. Decided to go the following day, no appointment necessary, Armen said it would take maybe 30-45 minutes. I was ok with the time, planned on working while waiting. When I arrived, Greg was there and helped me, very friendly and took me right away. No wait. I started working on my computer and before I really got much done, he came back and my car was ready passed and cert. transmitted to the DMV, all less than 10 minutes. Out the door price with a $10 discount was $53. (As of Sept. 2025). Excellent service, fast service, straight forward reasonable pricing is a recipe for success. I would recommend them highly and will be back again when I need a smog. Thank you. Enjoy!

Responsive, honest mobile mechanic -- made fixing my son's truck from out of town incredibly easy…read more I live in Ventura, but my college-aged son lives in Newhall while attending school. Recently he noticed the battery light stayed on and several electrical things weren't working correctly. Thankfully he drove the truck straight back to his apartment. Since I don't know any repair shops in the area and didn't want to deal with towing the truck somewhere, I searched for a mobile mechanic and found On The Go Mechanic. I reached out around 7 PM on a Friday, and he responded by 9 PM that same night. By 10 AM Saturday morning, he was already at my son's apartment. The diagnostic was $75, and he quickly confirmed the problem was the alternator. He explained that it might take until Tuesday or Wednesday to locate the correct OEM alternator and mentioned he prefers OEM because many aftermarket ones don't last as long. I appreciated the honesty. He didn't require a deposit and said he'd call when he located the part. To my surprise, first thing Monday morning he called to say he had tracked one down, but there were two possible versions and he needed to remove the old one to confirm which was correct. He came out, removed the alternator, sourced the right replacement, and returned shortly after. After a deposit for the part, he finished the job in about two hours, including reinstalling everything. He even sent me a video of the truck running with the correct voltage reading, which was great since I wasn't there in person. Because I was coordinating everything remotely from Ventura, this could have been stressful -- but he made the whole process very easy, transparent, and professional. Communication was excellent and payment through Zelle was simple. If you' need a reliable mobile mechanic, I would absolutely recommend On The Go Mechanic.
