Smog Check Concord
D&H Enterprises performs State required smog checks for many residents and commuters within Concord. Even though today's vehicles are sophisticated, computer integrated machines engineered to reduce smog emissions, it is still necessary to do a smog check to ensure that your vehicles is in proper operating condition.
California smog check state regulations require a check every two years on certain model years. In addition, Concord, and the whole of Contra Costa County, is an enhanced smog emissions testing area, which means that Concord and Contra Costa County residents are required to get their vehicles tested with specialized smog equipment that can actually simulate on-road driving conditions. D&H Enterprises uses smog check equipment that includes the state-of-the-art ESP System OneĀ® Bar-97 certified five-gas analyzer equipped with a dynamometer and Delphi Evaporative Emissions Tester.
