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.
