Customer Testimonials 


  • ★★★★★

    "A1 is not just auto repair, it is auto education. As one who is a novice at all things automotive, I have been very pleased with the care, thoroughness and communication. Every time I'm in the Bay Area my car seems to act up. But here, they fix the problem and provide you w details on the how and why. They also do more than a cursory diagnostic -- they let you know potential problems, signs to look out for, and urgency of potential repairs. I wish all shops were like this, the world would be a better place."

    Went into get my cadillac 1992 air conditioning converted to R34 and they were very helpful and knowledgable and fixed it with efficient service. The staff was friendly and courteous and checked in with me two weeks later to ensure everything was still working well. I highly recommend A-1 Auto Tech.
