An intermittent problem with my AC had been going on for several months. Two other garages had reported 'no problem found'. No kidding, I told them it was not consistent. Bill Smith's took the time to experience the failure and diagnose it. Then promptly made the repair. It's good to find a true professional that takes the time to actually solve your problem, instead of just wanting to send you a bill. I will definitely use them again, and recommend them to my friends.
