Welcome

In 1970 Congress passed the Federal Clean Air Act, which set quality standards for the nation. The act required areas that did not meet air quality standards to implement emissions control strategies or they would lose their building and highway funds. California did not meet the Federal Air quality standards. Therefore, in 1982 Congress decided to implement an emissions inspection program, currently referred to as the "Smog Check" program.

Middlefield Smog Check is one of the top 10 smog check centers in the Peninsula/Redwood city area. It is a private company categorized under Emissions testing without repairs. A test only smog center is a smog testing location which only performs smog tests, and does not execute repairs, but tends to be much more rapid, because it specializes in smog testing. In case of a failed smog check, we are very experienced in failed smog repairs, having done smog repairs 10 years before starting our smog testing business and having plenty of experience in auto repair, electrical and computer diagnosis, we can council you and point you in the right direction for a quick and accurate repair.
