McWilliams & Walden Inc. is a proud partner with San Joaquin Valley Air Control and Valley CAN, as well as a STAR certified smog inspection station. This means we have specialized technicians and equipment to perform smog inspections, diagnose detected issues, and provide repair if necessary. A smog test normally takes about 30 minutes to complete, and you are welcome to wait in our customer lounge with free WiFi. Should your vehicle fail the test, we’ll be able to provide you the reasoning and solution for repair. Because we are a licensed facility, we can take care of all repairs and re-testing in-house. Furthermore, we partner with Valley Clean Air Now (Valley CAN), a charity dedicated to helping emissions control in the area. We are a part of their Tune In & Tune Up program that provides emission-related repairs for vehicles that failed to pass the inspection.
