About Auto Diagnostics Inc

Auto Diagnostics Inc. is the premier car and automotive diagnostic service and repair service in the Worcester, MA area. We are a family owned and operated business that strives to offer high quality automotive work while ensuring our customers are treated with the highest level of respect and integrity. Since the owners of Auto Diagnostics are the ones working on your vehicle, you can be confident that you are receiving the best level of service possible.

Since 1992, we have been providing high quality auto repair in Worcester to our customers. We use factory diagnostics equipment to correctly identify and repair the problem the first time. Combined with our years of experience, we are typically able to provide an initial diagnosis over the phone to over 90% of our customers. Too often, diagnosing vehicle problems has become a system of trial and error, resulting in frustrated customers. We remove that frustration and fix the problem the right way. As cars become more complex, the source of the problem becomes more difficult to pinpoint. Using experience and technology, we are able to quickly identify and fix your problem.
