What We Do

Complete SMOG & Emissions Services

From standard biennial tests to on-board diagnostics, we handle every emissions requirement so you can focus on the road ahead.

Biennial SMOG Check

Required every two years for most vehicles in California. We run the full inspection and tailpipe test so you stay compliant with state law.

OBDII On-Board Diagnostics

For 1996 and newer gas vehicles, we connect directly to your car's computer to read trouble codes and verify emissions system readiness.

Failed SMOG Assistance

Didn't pass? We'll explain exactly what caused the failure and walk you through affordable repair options to get you back on the road.

Vehicle Transfer SMOG

Buying or selling a car in California? A valid SMOG certificate is required at the time of transfer. We make the process quick and straightforward.

Check Engine Light Diagnosis

That warning light on your dash? We'll read the codes, pinpoint the issue, and tell you exactly what needs attention — no guesswork.

Diesel SMOG Testing

Heavy-duty and diesel vehicles get the same thorough emissions inspection. We test opacity and idle emissions to meet California standards.
