About Clean Air Smog Originally established in 2002, Clean Air Smog was among one of the first Smog Check Test Only stations in San Francisco. At the time, Smog Test Only stations were a bit unknown to the public and the buzz was starting to catch on quickly, although there were already plenty in the Southern California area. Smog Test Only stations were endorsed by the Bureau of Automobile Repair and were set in place to standardize the test by providing a neutral, unbiased and consistent smog check result. Also, by having a Smog Only center, these facilities would provide a much more quicker ( 15 minute ) test, which would be better for the public. In 2004, due to retirement, the original owner stepped down and sold the business over to Earl Chua, the Senior Lead Technician at the time. While running the business with just his brother, Earl took the company to a whole new level by following a different business approach. He decided that the customer has to be the #1 focus of the company, even more than making a profit. Since then, business has grown tremendously through word of mouth and customer referrals. Whether its warming your car up an extra little longer, warning you of obvious failures ( check engine light ), or giving you tips on how to get your car ready for a smog test.. Clean Air Smog has developed a reputation as very trustworthy, dependable and reputable shop.

Fast, quick, cheaper compared to alternatives. They give you a paper copy of your smog check certification as well as send an electronic copy to the CA DMV that's tied to your vehicle's VIN.

Under new management and the smog cost $100 now I wish I would've known before maybe I would have shopped around a little bit. Very friendly and helpful new owner. Very professional.

I needed a smog check to complete my car registration, and I took to the Internet for a place that specifically was open on a Sunday because that was the only day I was able to go and I needed it...

Fast service and clear communication! Don't be deterred by the sketchy neighborhood and disheveled space, speed and quality count when your registration is due
