Octavo is awesomePosted on Mickey QiuTrustindex verifies that the original source of the review is Google. The best smog place in this area. Hands-down, I had the best experience I was in and out and literally five minutes. And it was the best price compared to all the other ones aroundPosted on Elsa CastroTrustindex verifies that the original source of the review is Google. Great experience at Clean Air. The entire process was quick, professional, and reasonably priced. I didn’t need an appointment and they were able to take me in right away and had me in and out in less than 20 minutes. The waiting area was clean and comfortable, which is always a plus. Even better, they offer a discount if you mention their online promotion, which made the service even more affordable. Getting a smog check isn’t always the most fun errand, but this place made it painless. I’ll definitely be coming back for my other car. Highly recommended if you're looking for a fast, honest smog check station in the city.Posted on Valerie KahkejianTrustindex verifies that the original source of the review is Google. Quick and friendly service!

Posted on Eamon G.Verified 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.Posted on Achromatic A.Verified No on appointment and total time was 20 minutes start to finish. And on top of that, less expensive than most other stations. AND incredibly nice staff. This is how the business should be done. Outstanding!Posted on Angelica P.Verified 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 before the end of the month. I came across Clean air smog star station and I am so happy that I did. it was fast, efficient, and more importantly I passed, but besides that the customer service was top-tier, Enrique was helpful, humorous, and a very pleasant person to talk to. I read in all the reviews that this place offered free snacks and drink, and that they sure did! I let him know that my kids were waiting at home for me and he sent me off with muffin, animal, crackers, some Cheez-Its, and vitamin water. I am going to make sure that I will send my friends and family to this establishment if they ever need a check themselves.Posted on Gerald V.Verified Fast service and clear communication! Don't be deterred by the sketchy neighborhood and disheveled space, speed and quality count when your registration is duePosted on Anjolie C.Verified Got a very competitive quote through Yelp, stopped in without an appointment, and was done within 10 minutes. Great experience!
