Smog Services

Everything Smog-Related, Handled Here

STAR Certified Testing

As a licensed STAR station, we can test all vehicles — including those directed to STAR stations by the DMV for gross polluter or directed vehicle testing.

Smog Repairs

If your vehicle fails its smog test, we diagnose and repair the underlying issue — catalytic converter, O2 sensor, EGR valve, evap system, and more — and retest on-site.

Consumer Assistance Program (CAP)

We're a BAR CAP participant. Qualifying low-income vehicle owners can receive up to $1,000 in state assistance for emissions-related repairs. We process the paperwork directly.

Check Engine Light Diagnosis

A lit check engine light is an automatic smog failure. We diagnose the DTC codes, repair the issue, and clear the light so your vehicle is ready to pass.

Pre-Smog Inspection

Not sure if your car will pass? Book a pre-smog inspection and we'll check your vehicle's readiness monitors and emissions systems before the official test.

All Makes & Models

We test and repair smog issues on all passenger cars, trucks, and SUVs — domestic and import, gas and hybrid — at a STAR Certified level.

What is STAR?

Why STAR Certification Matters

California's Bureau of Automotive Repair (BAR) designates certain stations as STAR Certified based on performance, accuracy, and compliance standards. Some vehicles are specifically directed to STAR stations by the DMV — including gross polluters, vehicles with repeated test failures, and fleet vehicles.

At Hyarcs, our STAR Certification means you can bring any vehicle — regardless of its history — and receive the highest level of smog testing and repair available in California.
