I just had my car "smogged" by Jon at A1, and I can attest that it was a completely pain-free experience. I was there on a Monday at about 9:30, and I was the only person there, no wait, so it was very quick. The waiting area is comfy, there is free Wi-Fi and a plug to plug in my laptop, and it even comes with a dog named "Roxy" (I think) who has the biggest brown eyes I've ever seen, I don't want to use too many superlatives, since in my opinion, a good smog-check should be pain-free and quick and not much else. I recommend A1. read more

Prompt, efficient service and only $54.00 with the online coupon. I highly recommend them! read more

This guy was so cool. Not only did I get in and out in under 20 minutes, but he helped answer a bunch of other questions about my car. Wow, what a help! I asked him how to change my power steering and alternator belts, as it would cost a lot for a mechanic to do that. I asked him if I could do that myself if I watched some u-tube videos, and he was so encouraging and informative. He even invited me to call him with any questions when I do it, and we could skype about it! That's going above and beyond the call of duty for a simple smog check! Can't remember the guys' name, but he's a super cool fellow read more

Quick, professional service. Even put air in the tires!! Would come again!! Hanging out with Roxy was a plus!! Thanks Jon!

Exceptionally kind, efficient and intelligent service is what I have experienced on two occasions at A1 Smog Shop. Jon, the owner, is a very special human being, and I am thrilled that he has expanded the available services to include various types of automobile maintenance/repair. read more

John was so amazing! I was in and out in 20 minutes. He is professional and customer oriented! Highly recommend his shop to anyone who is needing the service in a hurry for a great deal (cheaper than other places!) read more

Great service! Who rates a smog place?? I do, especially when the customer service is top notch! Best smog place I have ever been to. Highly recommended! read more

Can't say enough good things about this place. It's really fast and convenient, and Jon is really friendly! Adorable dog to hang out with while you're waiting, too! read more

Came in and did some paperwork. Had the car on the dyno and 15 minutes later I was done. The gentleman was very helpful and professional. Highly recommend this place read more

First time getting a smog check and saw lot's of reviews for $60-80 checks around Davis. Went in on a Thursday afternoon was in and out in 15 minutes and only cost me $48. A great value! read more

Great service from John. Very friendly. Did I say fast??!!! In and out in less than 20 minutes. Didn't even have a chance to finish reading my magazine article. Thanks John! read more

Overall a great experience. John was really helpful and was very quick. Even helped me answer some general questions about my car. Will definitely come back again. read more

In and out in 20 minutes, super friendly and adorable dog. Will return here in the future

Simple and easy process! The price can't be beat, and Jon really cared about making sure my car passed emissions and giving me the resources and advice necessary. Will definitely be using Jon in the future for smog tests. read more

I had a great experience at A1. As I arrived, I was greeted by Jon and Roxy, Jon's friendly dog. The test and certification are very affordable, and I was in and out in less than 20 minutes. read more

Took my business vehicle in on a Saturday afternoon. I was in and out in under 30 minutes. Great service, very friendly and an wonderful, social dog! read more

There are lots of other great reviews on here so I'll leave you with a bit of a different thought: Everytime I come in here I get the feeling that the Great Pumpkin actually visits this place on Halloween. It feels that *sincere*. read more

I was searching around for a Smog Station and every other place I researched was quoting me ~$75, FOR A SMOG CHECK. Luckily I work in Davis and found A1 Smog on Yelp along with his coupon for $43.75+$8.25 certification fee ($52 total). Unheard of. Also unheard of was how fast (15 minutes) and friendly (I mean, there was a lovable dog there to pet the whole time I waited) this place is. Definitely, highly recommend. read more

Great service, effortless process, awesome price. Can't say enough about Jon he was straight up and let us know right away we needed to address a pesky check engine light first. We came back after getting it fixed and he got us in and out in no time. Roxy does her job well and kept me company while waiting for just a bit. This is the place to go for a smog in Davis, hands down. read more

The most comfortable and relaxing mechanic shop I've ever entered. Don't let the size bother you, you get free water, coffee, comfy seating and plenty to read with cool refreshing air keeping you feeling good even on a hot summer day. Bonus: there is an awesome dog named Roxy just wandering around doing her thing. Thank you Jon for the great experience and wonderful customer service. read more

This shop just opened this month, the owner is a very pleasant person. Most SMOG check places I have been to in the past had really unhappy people running them, not this place! I was in and out in only 15 minutes and printed a coupon online so it was only $40 read more

Great place to drop in without an appointment and great price compared to others in Davis! And you get to spend time with the adorable dog roxy. :) read more

Outstanding customer service provided by Jon! Best price and service for smog checks in Davis hands down. I went in around 9am before going to work and the experience really brightened my day. Jon and his awesome dog were very welcoming. I have a 1984 Nissan 720 truck and I wasn't sure if I'd still pass. Jon worked diligently and had the job done in less than 20 mins. He even did me the courtesy of reconnecting a loose vaccum line to my carburetor. All in all, I was very pleased I chose to go here. read more

Here is what I think you'd want to know. 1. Location is not that easy to find. Behind another business, but just look for the signs. 2. Not such a nice waiting area, but I was there on a super hot day (over 100). 3. This is a family-run (including the dog) business. 4. Quick service (I'd call ahead to make sure they are not backed up). 5. Reasonable pricing (about $20.00 less than some other quotes I received). 6. If you want value for your money, you don't want to waste time waiting around, you want to support a local family business -- I believe you will be very happy with A1. read more

Took my car here about two weeks back. There was a person before me, but still got out in about 40 mins. The process was quick, and simple. Great place! read more

Service was quick and easy. The dog was a great touch. Price was less than expected. We will use A-1 Smog again.

like others have said, you have to work to find this place but i'm glad i did. read all the positive reviews on yelp and have brought multiple vehicles here for their smog test. was able to get in and out very quickly. customer service is very important to me and it's top notch here. the dog is a nice bonus to make the time pass more quickly. they're going to start doing oil changes and brakes so i'll know where to go when i need those done. read more

Outstanding service. Highly recommended! And A1 Smog can do oil change, tire rotation and brakes. The owner is a great Dad too!

I have found my new mechanic by chance. He got me in for a smog check immediately and went ahead with his services though I realized I had forgotten my purse, graciously allowing me to get payment after the fact. I had just left the smog place I usually go to, feeling as if the proprietors of the place didn't value my business, and chose A1 due to it's web presence, proximity to my home, and readily available coupon. Now I'll be sure to go back because of the efficient service and general goodwill shown me. read more

Was in and out within 30 min as there was another car ahead of mine. While my car passed, the car ahead of me did not. But I was very impressed by Jon's patience in explaining to that owner why they failed and how to fix it. You also get a free re-test in case you fail. Would strongly recommend! read more

I came close to closing time but Jon still generously accepted me. He gave me an estimate of half an hour but was done in 20. Only ~$50 for a smog check. He's very friendly and I wish him the best of luck with his business. I'll be back in the future for all of my upcoming smog tests. read more

Jon is friendly, helpful. reasonably priced, and fast. What else do you need to know?

My favorite smog place I've been too! I called ahead to make sure there was no waiting and he said to come on in! The owner was very friendly and quickly saw to my car! I was in and out in 20 min! Great prices and wonderful and courteous owner will definitely make me come back here for future smogs! Doesn't get better this for a smog place! read more

If there were more stars available - I would award it because A1 Smog deserves it. Owner, Jon is best. He is a competent smog tech, skilled light mechanic professional and very personable. His fees are fair. Parking is plentiful, right off Chiles Rd - 80 frontage road. The wait area is cool and clean. Shop dog Roxy is adorable and friendly - though initially on the shy side. I like petting her while waiting. It calms me down and lower my blood pressure. Last week Jon took care of my Outback smog certification. I am good for another two years. My wife's Accord is next. So Com'on Davis. Bring your dorm-mate, tell your RA. Call your classmates and spread the good word! A1 Smog is #1 read more

I'm glad I found this place. Nice people and did a good job on my brakes. Will take my car for service there from now on. They only did Smog before but expanded to General Repair, brakes, Oil Change, Tire Rotation etc. I have always preferred local business because you can develop trust and you know who's working on your car. read more

Really great service. Jon was able to smog my car right before he was about to close. He did not seem in a rush either! Overall I recommend A1 to locals in Davis and around. Make sure to use the coupon on the website to get a good discount! read more

I'm usually not one to post on Yelp but the service and treatment from the workers at A1 smog are excellent. They have always been attentive and competent with the issues I've had for my vehicles read more

Awesome!!! Excellent!! John is the best and his friendly dog Roxi is just the cutest! This is the place to go if you need a Smog. 5 stars

Fast friendly service! This place rocks and very helpful, and in this day and age its a breath of fresh air to find an honest hard working shop. read more

Best Smog experience I have had. I have brought 3 cars to John's shop in the last 4 months. He is always friendly, he is quick with my cars, and the price is right. The shop always has plenty of interesting magazines and papers to read while you wait, and there's a shop dog who is sweet. This is the only place I will get smog checks any more. read more
