First and foremost, James is a good person, trustworthy, knows his business inside and out and…read moretakes great pride in providing an uncompromising level of service to his customers. I hired Quantum Mobile Mechanic to fix a brake light issue, and James did a good job of diagnosing the issue in a quick amount of time. He didn't have the part in his van, it wasn't a common one (brake position switch) so we rescheduled for a couple of days later. What struck me about James as a business person, was that he didn't just run a test, drop a quote and drive away, he took time to get to know me and we had a good conversation about his business, and how my son wants to be a mechanic. I can't recommend this business enough, the ease of scheduling, fair pricing, and excellent customer service. Really happy that I chose Quantum! I hope you are too!

UPDATE: I had already tightened the bolts (and I have some video but did document all of them), and…read morereplaced the ones that were missing, because I didn't want to bother you about it if I could figure it out and fix it. You were here from 3:38 to 3:53 according to when I opened and closed my garage. Thanks for saying my car is a diesel, there's timing belt slop, and my alternator is going bad; I don't recall the fourth one. Like I told you when you showed up, I didn't want to text you about it because you complained about people saying you broke stuff on other jobs. You did actually break my hood release mechanism, but the plastic was 11 years old and you told me about that, and the zip ties are still holding. We both don't know what the noise is but I know 100% it started the first time I drove the car more than 5 miles after you worked on it. If I always listened to loud music then this wouldn't be an issue and I would just be enjoying my ice cold ac. I've maintained and repaired this car for 120k miles. I'm not legally allowed to do ac work so I called you. Next time I'll get the certifications and the equipment. Cheers ORIGINAL: My ac works great but I've had a super annoying rattling noise since the work was performed. I've torn apart most everything that was touched during the repair and found a lot of loose bolts but still can't get the rattling to stop. I'm assuming it's just a bad quality expansion valve at this point. Not worth dropping another $1500 to resolve but definitely not calling them back for future work.
