Incredibly helpful in diagnosing a software issue that was causing an incorrect smog test failure, and retesting for free once it was fixed.

Called in to get a smog check, they told me to come at a specific time. When I arrived they said come back in 3 hours.. waste of time

Was able to get a walk-in smog check here around 7:45am on a Thursday right away with no wait. Alli, the owner/attendant, was super friendly and professional. I was able to get everything I needed for my DMV renewal. The smog test plus certificate came out to be $88, which seemed like a good value to me! There's a nice co-op bakery next door to chill at while you wait for your car to be checked. Five stars all around! read more

hands down the best, had me out in 20 min. the guy there was super awesome and quick but not rushed. While waiting i noticed they have some of the lowest gas prices so i had to fill up which he kindly did that for me as well. read more

Quick, professional, and friendly! Valencia Smog made my smog check easy and stress-free. Great customer service and fast results. Highly recommend! read more

Good service for a fair price. I left my car and walked down the street for a coffee. After I was done I walked back and the test was done. Not a bad way to spend an hour. read more

Easy, fast and great customer service. I went over the weekend (early Saturday) and they did in less than 39 min.

The technician is very considerate, kind, helpful and highly professional. The first time I did not pass the smog check for my ten-year-old car because a pipe was broken. He kindly told me with great patience where and how I could change this broken pipe. His policy is no charge if not passed the smog check until it is passed. I highly appreciate his honesty and help. I recommend this station highly. S.W. read more

Great service and smog check was done very quickly. I just drove in one Saturday and was able to get in and out in 15 minutes. They were a little more expensive than other smog checks I had recently used in SF but still recommended. read more

Came here after quickly glancing at Yelp reviews for smog checks near me. Ali answered the phone right away, got me in for a smog check when it was convenient, and was incredibly quick and friendly. Appreciate the great, easy service & friendly attitude. Highly recommend! read more

Not "star certified" whatever that means so we couldn't use them this time. But other smog checks they've been easy, nice and fast. Nextdoor is a cafe. Make it your first choice unless you need the extra cert. read more

Valencia Smog is the best! Ali provided not only the most efficient and affordable smog check but also above and beyond customer service. There was zero wait time and my car was done within 15 minutes. Absolutely no extra effort put in on my end aside from signing a paper and handing over my credit card. Would highly recommend Valencia Smog and Ali! read more

This was my first time doing a smog check. When I got the notice from DMV I gave a big sigh and was like, "Great - here's something that's going to be a total PITA and take time that I don't really have." Well, to my surprise, thanks to to Alli and Valencia Smog, it was painless and quick. I called ahead and Alli saved me a spot. I arrived, gave him the car and went to get a coffee while the work was done. 20 minutes later he calls, it's all done. In and out, totally painless. Thanks for making my first smog experience fast and easy! read more

The best smog check in town! Couldnt believe I got in and out within 15 minutes. Alli was professional and made sure to educate me on the renewal process. Anybody living in the Noe Valley area must come for their smog check here! Gas up, get a cup of coffee next door, and enjoy the area! Thanks Alli! read more

Have been meaning to write a review . . . came here about a month ago after making an appt with Ali. As others have noted, Ali was super friendly and attentive. The breakdown occurred when it turned out that I needed a STAR certified station, which this isn't. I'm not an expert and had no idea that there are two kinds of Smog Stations. Ali on the other hand should know this, and IMO should confirm which one you need when making the appointment -- rather then after you arrive. As a result, I was late to work and had to scramble to find another station and park my car elsewhere at a greater expense. Great service means being more mindful of customer situation. read more

Everything went smoothly. As others have claimed Ali to be one of the nicest people they have ever met......I cannot say as I did not spend too much time around him. He is professional and friendly and seems to enjoy his career. So no complaints. He is not the cheapest but re-test is free if you need one! I told him he had a lot to live up to with some of his Yelp reviewers positive comments! read more

Quick and easy--can't get better than that! Called yesterday to make an appointment for today. I showed up on time, and was helped right away. To pass the time, I headed over to the Mission branch library to browse, and within 20 minutes, I got the call that the car was ready. read more

Very efficient smog check. I came in for a smog and got my car registered with the sticker I needed the same minute! Why go to the DMV? I couldn't believe how fast it was! Thank you so much Valencia Smog! read more

Came in for a smog it was quick and customer service was amazing I will definitely come again

Super, super friendly service... and Ali definitely knows what he's doing. He's an expert professional - I took my car to him for a smog check and the whole thing was easy, painless, comfortable and quick. read more

So quick and efficient! I've been here twice now for smog checks. The owner is so friendly and helpful. Definitely recommend!

Called Valencia Smog on a Saturday morning and was able to bring my car to them about 45 minutes later. Ali had me in and out in under 30 minutes. No issues. Great experience. Highly recommended. Very close to the Mission branch of the SF Public Library, so you can pop in and pick up a library book. read more

Alli was great. Had an appointment and was done in under 15 minutes. Would absolutely recommend - and they are open on Sunday.

Ali was such a friendly guy. Really quick service and very convenient to be open on a Sunday! Thanks

Great experience ! My cars catalytic sensor wouldn't turn on and therefore I was unable to pass smog inspection. Ali told me drive the car another 100 miles as it had to run through a number of system checks in order to come on. Long story short it worked and I passed ! Many thanks to Ali and everyone at Valencia Smog. I'll be back for sure. read more

Ali was wonderful! The service was kind and professional. I was in and out of there in under 20 min. Highly recommend!
