I needed to get my 2007 Tacoma smogged again. I called and I was able to get in the afternoon. Service was great and quick. I Appreciated the fact the smog gets electronically sent to DMV. The waiting room was even comfortable. I'll be using the smog connection again. read more

Amazing customer service and a quick check for a great value! Extremely happy with taking my car here and would highly recommend!

Great experience and fast! Very professional and had no issues. Got me in same day and waited 10 mins and on my way!

Had to get my smog checked for the first time & Smog Connection was easy & straight-forward; I've never had to get my smog done when renewing my car registration and Timm was super nice and told me how it works- not hard of a process at all but was nice information to know for the future! Very efficient, I was in & out within maybe 15-20 mins or less. Would recommend! read more

Easy to make an appointment and super friendly employees! I was in and out of there in 15ish minutes. Definitely recommend!

Tim was such a huge help when our truck wouldn't pass smog. We took it back a few time and he took time out of his day to run a few tests for me. He's been smogging my cars for years and I will never go anywhere else. If you have not been there I'd say check them out read more

Close to my house. Quick too. I'll come here from now on that's for certain. Highly recommend them.

Had an appointment at 2pm and was out in 15 minutes. Tim was professional, fast and efficient. Definitely will continue to bring my car there again! read more

The Smog Connection - Front door of the business - Smog Check Stations Near Me - Vacaville, California

Excellent service every time and a great price. We were in and out in 30 minutes and everyone always has a positive attitude.

Came in for my inspection and was able to get in down in 30 minutes during the day. The owner does the work himself, kind easy going guy. Small shop that's gets the job done. Wonder how the guy that was literally leaking and blowing smoke after I left the shop did. Would recommend without hesitation. read more

See all

Tim is a long-time Vacaville businessman and a really personable and legit technician.

Professional and honest service. Very experienced in this field!!! The quality and service superb!!! Timely as well.

Not true. It is very easy to verify you have sufficient monitors completed.with a simple OBDII hand-held scanner. Vaca Valley Auto Care does that, and also that other shop in that plaza. read more

I highly recommend this place for your smog check! I came in on March 8, 2022 and I can honestly say that this is the best experience I've ever had when I had to get my car smog checked! They got me in for an appointment very easily! When I came, the guy did it so fast! Which was especially helpful since I had my 6 year old with me. The lady working the desk was very nice and I was very grateful for the whole experience! They have a cute little waiting room for us to wait and it only took just a few minutes! It literally took only about 5 minutes from the time they started to when my car was done! Hands down, best place in town! Thank you!! read more

This is the best place in Vacaville for smog service! Very nice staff and great service! See you next time! read more

Glad I checked out Yelp before going to get a smog check. Went to The Smog Connection because of their 5 star ratings, when I pulled up I was a little bit confused about where the entrance was, but the gentleman doing the smog check was in the garage and directed me through the shop into the office. Super quick and very friendly! Awesome place to get a smog check done. read more

When I called the receptionist was really nice and she made an appt for my smog check. When I arrived they got me in right away at the appointed time. It only took about 15 mins. The owner and the receptionist were friendly and professional. I will definitely come here again. It's been a couple of months since I was there but wanted to make sure to leave a good review. Better late than never. read more

Extremely friendly and kind staff, smog test was done quickly as well! Awesome environment and was super easy!

I don't leave reviews often. But the employees here are two of the nicest people I've ever met. It was also fast and efficient. What a great experience. Thanks again y'all. read more

Hands down the best place in Vacaville to get a smog check. Lord knows we all dread opening up mail from the DMV and seeing the smog check requirement show up on your registration renewal. The Smog Connection made everything easy when we had to get a couple of our cars checked out earlier this year. My coworker had recommended it and I'm glad he did because it was such a quick and painless experience. I called ahead and made an appointment and was literally in and out of there in less than 10 minutes. The gentleman there was very nice and courteous and made the whole process a piece of cake. Highly recommend! read more

Took my car in for a smog. They were so prompt. The staff was very nice and the job seemed like it only took minutes. Great job

First off this smog test establishment got me in same day at a great time. I have been here before (2 yrs. prior) and my experience was the same. The gentleman who helped me was friendly, attentive, got me in and out quickly, and very reasonably priced. If your looking for an honest, friendly, and fairly priced smog shop this should be where you go because you will not be sorry. A few pointers: wear a mask as you can wait in the lobby while your car is being tested, make an appointment, have your car registration slip or insurance card ready, dont come if your check engine light is on (it wont pass), they send your passed smog information directly to DMV. Hope this was helpful, thank you Smog Connection, appreciate all you do! read more

As usual, Tim from smog connection took great care of me. I was in and out right on time. Thanks!

Timm's work was very quick and painless. I waited about 10 minutes and he had 4-5 cars before me. He was very nice and talkative during the process. Also, I learned he used to drag race and his shop is full of old blocks! Will definitely come again when I need a smog. read more

Timm was awesome. Made an appt and was in and out in 10 minutes. I definitely recommend Timm at The Smog Connection.

Very friendly, professional people here. The guy that smogged our vehicle was literally done within minutes. We will definitely be using this place for smogs from here on out. read more

Timm had the car in within 10 minutes of check in. These guys are fast, yet thorough with attention to detail and great customer service.

Really awesome local place to get your car smogged. Called at about 9 am for an opening later on in the day and they had an opening. We were in and out in about 30 minutes or less. The owner is really friendly and welcoming. We have been here once before and after 2/2 great experiences I believe this will be where we go from now on. read more

Excellent service. Quick and friendly. Highly recommend. Shout out to the owner! Thank you for a very pleasant experience. I have been taking my car to some random smog place and my boyfriend told me about Smog Connection and we took his car today and I will come here forever!! read more

Thanks to yelp I found this place. The gentleman greeted me, and walked me into to do some paperwork and started on the car right away. Very friendly and welcoming. 49er fans come here! Has some cool classic items in his shop. Nice waiting area with tv and comfy chairs to relax on and wait. I think he will finish my car before I finish my review. Quiet and relaxing location next to a Gym and Barber shop. If you're looking for a place to get smogged gotta go here read more

I've been coming here for the past 8 years and have always had nothing but outstanding service. Fast, efficient, affordable and friendly. Timm is a real, world class guy. This place in my opinion is top notch, the best smog station in Vacaville. read more

Timm at The Smog connection was recommended to me after a bad experience at another smog shop. He was extremely helpful! He was fast, affordable, super friendly and explained things with no nonsense. I highly recommend you check out The Smog Connection for your next smog. read more

This my second time using the Smog Connection. They are very accommodating. I had an appt and was able to change it to a day earlier. The receptionist and the owner Timm who does the test are very friendly and efficient. I will always use them for my smog needs because they appreciate the customer which you don't find anymore. read more

As simple and easy as the first time I went, amazing customer service and genuinely friendly people. Today, I brought my husband's truck in and they got everything done for me in less than 15 minutes. Quick, easy and "painless," as Timm says. I'll continue to go back, always pleased with their professional service! read more

Awesome service! I needed my 2012 civic smogged for new tags and they had an appointment same day for me. The front desk woman was very friendly and helpful by telling me the different papers I would need to bring to my insurance when getting my new tags. The owner/man doing the service was also very friendly and I appreciate the fast work. The appointment itself took 5-10 minutes. If you're looking for friendly people to work on your car and need it done fast, this is the place to go. read more

I have been taking my cars to Timm for SMOGing since FOREVER. His service is always efficient and he and his receptionists are always very cheerful. On the very rare occasions over the many years when a vehicle didn't pass inspection, Timm's counsel is always SPOT ON! He has an extensive knowledge of automobiles and has willingly shared it with me. Timm is definitely the GO-TO-GUY for SMOG inpection in the Vacaville Area. --Dick Klein read more

Called this morning to get a price check on smogging my car, Lady was nice when answering the phone she said they had a special going on 48.00 with cert to smog my 2014 car. Didn't like the price so called another shop superior smog guy was nice said it's 45.00 the door including cert and they have a senior discount and a military discount, with my military discount it's 40.00 out the door including cert. senior discount it's 25.00 out the door Including cert the guy said most seniors are on a very fixed income and his business is all about helping out his community! Def not going to smog connection I'm heading to superior smog now where it's cheaper and no wait or appointment needed ! The reason I'm leaving one star is due to the fact that their coupon/Special is higher then another shops regular price with out any coupons! read more

Tony is an amazing businessman! Taking a colleague's car in for a smog check, Tony wonderfully explained why he suspected the vehicle failed to pass & suggested targeted repair explorations. In no way was my experience disappointing. Tony helped identify how to get this vehicle up to standard rapidly & with professionalism rarely seen in any other industry. Highly recommended & will joyfully patronize Tony's business in the future. read more

Great experience with The Smog Connection. I called today and got an appointment for the same day. The woman on the phone was polite and friendly. They gave me wonderful instructions on where to park and what to do if they weren't back from lunch yet. They came back right when expected. They assisted me immediately. They told me the price and explained each line item. They asked for my DMV paperwork. The gentleman promised it would be quick. He wasn't kidding! It was minutes. I was given my paperwork and the check was submitted to the DMV. I was back on the rode so quickly I was able to pick up lunch and wash my car. I was back to work early from my break. I found them on google and they had excellent reviews. I see why they had excellent reviews! This was quick and painless! I will be using them for every smog check. read more
