Smog Inspection Station and Repair in Concord, CA

We are a STAR Certified Smog Station in Concord, CA

Today’s vehicles are sophisticated, computer-integrated machines that are engineered to reduce smog emissions when in proper operating condition. California State regulations require smog testing every two years on certain model years. Non-passing vehicles must get smog repair in order to pass the emissions tests. In addition, Concord, and the whole of Contra Costa County, is an enhanced smog emissions testing area.
This requires the testing of vehicles with specialized smog equipment that can actually simulate on-road driving conditions. D&H uses smog testing equipment that includes the state-of-the-art ESP System One Bar-97 certified five-gas analyzer equipped with a dynamometer and Delphi Evaporative Emissions Tester.

Failing a smog check can be a real headache. Fortunately, D&H is here to make the process as painless as possible. For over 20 years our ASE-Certified Technicians have been keeping the residents of Concord in compliance with California state law.

We are equipped and have the expertise to perform smog diagnostics and smog repair to all systems and components on those vehicles that are residing, commuting, and passing through Concord.

Only quality parts to pass the state inspection

Quality emissions repairs begin quality parts. That’s why we use only OEM and OEM approved components on all of our repairs, to ensure your vehicle passes smog inspection for many years to come.
