Took my SMOG appointment and was ready for me on time. Operator went out of his way to show me a bad hose in my engine bay. My time and my equipment were respected and I would definitely return for another SMOG check in the future. Pricing was competitive and I was done in a out 30 min, including the extra hose issue he showed me. read more

Wonderful service. They took me in even though they were about to close. They were done within 15 minutes. polite and lovely people. Thank you! read more

I used this shop over the past 10 years and I'm always satisfied with their quickness and mannerism. The price isn't too bad either.

Fast Efficient and Friendly what more could you want in a smog check : ). I called ahead and was able to just drive on over. As I was pulling in, someone else pulled in just before me, but because I called he actually took me first. He gave me the paperwork and the price and true to his word, he was done in 15 minutes. There is seating nothing glamorous, and also a taco truck so if you're hungry, there's food right there in the parking lot. All and all very, very simple and easy. read more

Loyalty matters. My SO comes here every time for smog checks. They're not the cheapest quote around, but the friendly staff makes it worth it!, Plus, who wouldn't support a shop that knows how to clap back with humor at a drunken review? That kind of personality makes them stand out. read more

Needed a very last minute smog for a car sell. Called on New Year's Day, every where else was closed. He squeezed me in. Very fast, professional and honest. read more

Requested a smog check last night via yelp. Said was very prompt at returning my email with a reasonable price quote that was honored when I got over there today. Fast service, courteous, and fair. I will bring my car back to A-1 smog again when it's time for its next smog check. read more

The Vallejo smog station at 2707 Sonoma Blvd will try every trick in the book not to honor or even recognize their own coupon even when you show it to them. I would rather go to another smog station and pay a few dollars more rather then deal with the crooks there. read more

We were a party of 4 women. We ordered a lot. Everything was extremely bland and unremarkable. We had all been there before but not for some time. We had apps, pasta and pizzas. It all sucked. The only thing we all liked was the bottle of overpriced wine. Delicious. The atmosphere is wonderful. But you can't eat it. read more

Brought in my 84' BMW for Smog. Staff is kind and respectable. Will continue to bring vehicles to A1 Smog

Still the only place I want to go to for smog in Vallejo! I think this was my fourth time coming here and I had great service as usual. There were two cars ahead of me, but I was still in and out within half an hour. The man working kept me updated along the way so I was never left wondering about the status or wait. Great smog check service and don't forget to check their website for coupons! read more

A1 Smog Star Certified Station - Smog Check Stations Near Me - Vallejo, California

I came in to get my smog done because I thought it was up for renewal. I gave him my paperwork and he told me that I read my paperwork wrong and didn't need to get one at this time. He could have easily taken my money by doing an unnecessary smog test on my vehicle. But instead, he was an incredibly honest man who now has a lifelong customer. Thank you! read more

A1 Smog is top notch. Sergio was a major help with great advise on how to care for my 31 year old car. Excellent, cheerful service. Thank you! Please check them out next time you need your car smogged. Thank you very much! read more

I've been going here for 10 years and the same owner has told me what exactly to do to fix my car in order to pass. He's also the cheapest I've been to. He hooks me up for being a returning customer! read more

My dad (older gentleman) Came in to get a smog and he failed it for aftermarket cat not having the correct carb number said it was "tampered" but the reality is this tech here didn't do his job properly by inspecting the car properly. After failing here I was advised to take to Vallejo smog dog in Vallejo and the technician found the numbers on the side of the cat converter verified that that number was good is in compliance with the year make model and engine family and it passed. The tech at Vallejo smog dog saved us money by doing a through inspection and going above and beyond before failing my car and making me buy a new cat (which I already did but decided to try a more honest smog shop before welding it in.) Now filing a complaint against him to get my money back with the bureau of automotive repair read more

The owner is a top notch guy. Very friendly, straight-shooter, honest businessman. No "mickey mouse" smog here. He's been in the business over 20 years, and he knows what he's doing. Highly recommended. Prices are very competitive. Pro-Tips: Get the coupon online. Also bring cash and you'll save another $2.00. Good job A1! read more

I was able to make a same day appointment. The job was done on time in a professional manner. they were respectful of my time and comfort.

Called ahead for pricing and Sayed (sp?) was super helpful. Was able to get in the same afternoon. Once I was there, I was in and out in 10mins! Important thing to note is that pricing is based on vehicle type and year. Pricing was competitive and service was great! read more

See all

Been going here for years now. One of the few places you can go to have your car looked at and not have to worry about getting ripped off. He is honest and very professional. I will not take my cars anywhere else. read more

Great experience from start to finish. Nobody likes getting the "Smog Required" note from the DMV, but A1 made it pretty painless. I made an appointment, and they were ready to go when I arrived. A few minutes later, I had my certificate and was on my way. They took the time to answer my questions and made sure I was comfortable with the testing process. Will definitely be back the next time I need a smog certificate. read more

Great service. I bring both of my cars here when Smog is due. Also conveniently located by my job in Vallejo

Great shop to smog your vehicle. Been going here for years. Very friendly and fair prices.

I return to A1 Somg every time my Subaru and Ford need a smog. Saeed is very knowledgeable and friendly. I recommend A1 smog to anyone in Vallejo because it's hard to find friendly, hard-working honest people in this town. read more
