Excellent service! I didnt have an appointment, and they squeezed me in. Even without an appointment, they were super fast. I think I waited 15 minutes for the test. Everyone was very friendly. I will definitely be a repeat customer!

I am a repeat customer and will never go anywhere else. The customer service is tremendous—all smiles, genuine kindness, and professionalism. This is a company that truly cares about taking care of its customers. They are fast, efficient, and do a great job. They are a fabulous asset to Vacaville.

Service was quick and the shop and waiting area were clean. The staff was friendly and professional. Very pleased.

The service was quick and easy. The gentleman who helped me was kind and professional. Would definitely return!

Repeat customer because this is the friendliest fastest shop in town! Not far from DMV and they were done with my car in less than 15 min!

Took my older car here twice now. Closest place for me and very happy. Super friendly people, always a pleasure.

Super nice owner and receptionist. Fast service and great customer service. My dad had been telling me about this place for awhile. He passed away in November 2019 and I figured Id try them. Id return in a heartbeat just to give my business to these kind people again.

The best smog shop on the planet! I wont go anywhere else! The owner is a patriot, and a true American!

They are seriously awesome. I went somewhere else before this & they were so rude & did nothing right compared to this place. The customer service here at the Smog Connection is amazing & i’m always in & out super quick! Great prices, great service, & happy customers. What’s better than that? 😄

Fast fifty pass.Been going here for long time,almost 20 years with 4 different vehicles and always good experience.

Fast service and great customer care . Been going to The Smog Connection and I have had consistent great service .

I’ve gone here twice now for two different cars, and each time has been a pleasure. They are very kind both on the phone (where I had a couple questions) and in person. The process is so fast and efficient that you’re there for typically no more than 15 minutes, and they make me feel right at home in that short window. I’ve been lucky enough to pass my Smog tests, but I’ve read reviews that they will be incredibly helpful/informational when the time comes that it doesn’t. I have confidence in The Smog Connection and will continue to bring my cars here! Thank you Timm and Team!

The only place i go because Im always treated great and they take great care of my vehicles. Its nice to know that my vehicles are being handled by a professional. 14 years theyve always been trustworthy.

Timm is the best! excellent customer service and very quick. Ive been coming here for 20+ years exclusively. Dropped in really quick today and was out in 15 minutes wow!

I started going to Smog Connection, probably over 7 yrs ago. The owner Tim is a super nice and honest guy. Only 1 time as I recall, I was dragging my feet getting car smog done..Tim didnt have any appointment available. I started looking, knowing I was cutting it close. I went to another place..(wont give name). The happy smile, not there..but I paid way more. No way will that happen again. Smog Connection is the best.

Been going here forever and the owner is such a gentleman kinda cute too. Anyways staff is very kind and always quick!! Highly recommended!!

Ive been here multiple times and Ive always been able to get an appointment. Friendly, fast and professional. Highly recommend.

Most knowledgeable, fast, reliable and most cars dont need to have an appointment. Highly recommended.

I appreciate Tims professionalism. His team is always quick and courteous. I wouldnt take our fleet anyplace else.

Love this place. Went for the first time the other day, got a quick same day appointment, car was in and out fast, the customer service was AMAZING, good, honest, Godly man, would reccomend here over anywhere.

I got there at their lunch break sign said back at 2. They were back at 2!! By 2:15 I was on the road, test done. Friendly quick efficient clean.

Tim is honest and probably the most mellowest guy ive ever met. Great service.

The best smog test center in Vacaville. Tim is thorough, extremely knowledgeable, and professional.

The best smog inspection shop Ive ever used. Tests by appointment, so almost no waiting. A small business that thrives on word of mouth with an owner that cares about his reputation. NEVER does anything shady, Always passes cars that should pass. (You would be surprised how many subtle things can produce a bogus fail at the disreputable shop). Always polite, organized and fast. Charges the going rate. STAR certified station.

Best smog in town. Tim is super friendly.

Cheap and great people who work there with 5 star service only going there for now on.

The owner was so nice and helpful. He serviced me even though he was about to close.

Hes amazing fast friendly and get the jod done right.

Ive been a customer for years this is the best shop in Vacaville or better yet the Sacramento valley area. My only dissapointment is that he is a fortyniner fan..lol too bad

Nice place, very helpful and they have people who speak spanish which is very helpful.

Ive been coming here for years and never had anything other than great service. Timm is great and I will continue to bring my vehicles to him.

Simply the best! Fast, Professional, and very nice people.

Super fast, nice staff. I was in and out and back at the DMV in no time.

Great place, great owner and fast friendly service
