I have been going to Smog Connection, Timm is the owner, for longer than I can remember. My car is 20 years old and every time a smog is due, I call Timm. I only have had one problem and it was a bad gas cap. Timm used a cap he had, told me I had to replace mine, and my car passed with flying colors. His price is reasonable and I am usually in and out of his shop in under 30 minutes. My only complaint is that he is a SF FOURTY NINERS fan. Being a RABID & DIEHARD GREEN BAY PACKER fan, you can see the problem! Thank you Timm for taking care of my car for the last 20 years. I will continue to support your business for as many years as I have left. read more

I called ahead, and while they allow walk-ins, an appt was recommended. I was able to secure one for later in the morning. I planned to run an errand and head straight over, unfortunately I left my paperwork at home. Not knowing they could do the testing without it, I ran home and realizing it was already time for my appt, I called to let them know I was running late. Thankfully, the next appt was already there, so we were able to basically switch spots (them taking the current time that had been mine and me taking theirs). The woman in the office was so helpful and kind about it! I got there before the updated appt time while the vehicle before me was finishing up testing, and we were in and out like a flash after that! Very friendly, fast flexible service, and great pricing. All in all, as painless an experience as smog checks can be, would recommend! read more

My husband raves about how efficient this place is. We live in Sacramento and we take both our cars here. Fair price and super quick. Moving cars in and out every 15 minutes. What more can you ask for? read more

We needed to get our car smogged and didn't know the first thing about it. Called Smog Connection and they got me an appointment to come down in 20 minutes. Once we pulled in we were greeted by Janice who helped us with all our paperwork. She was such a friendly and welcoming part of our experience. Tim was super professional and got our car done in 10 minutes! We are so happy with how easy it was and they even have a great little waiting room. Highly recommend Smog Connection! Thanks for taking care of us. read more

Easily made an appointment during the week for Saturday morning. Nice big sign when I was driving down the street since my gps did not say what side of the street it was on. Waited on the comfy sofa and it didn't take long. Timm was well-mannered and explained the fees clearly. I appreciated his gentle kind energy and how easy everything was. Thank-you! read more

Smog check made an appt didnt take long. Customer was great . I would recommend this place .

When our truck was due for a smog we looked up places to go via yelp and Facebook and we were guided to The Smog Connection. They were able to get us in same day and service was quick. When we were looking at places to go, this place had some of the best pricing. They have gained life long customers and we have referred many others to them including my mother in law. read more

I came here without an appointment on a Tuesday before lunch. I didn't expect them to be able to take me in, usually these places book out. I came in and they said they could fit me in if I waited just a little bit. That was awesome. I sat in the waiting room and before eight knew it my car was smogged. The price was exactly what they quoted and my info was sent directly to BAR. This is my new go to smog shop. read more

Realized I needed a smog to complete my registration that was due the next day. I called them late & they gave me a noon appointment the next day. Pulled beside & behind the building, they have lots of signs. Handed them my keys & DMV paperwork & they had my car smogged in 8 minutes. That is the fastest I have ever had a car smogged. They really have their process down & make it so quick & painless. Waiting room is clean, has two chairs & a couch. Paperwork was easy & quick, both the staff I talked to were very friendly & nice, Best of all, this was the cheapest we could find in our area. Even considering Your Town coupons, with no coupon The Smog Connection was still the cheapest ($55) out the door. I will definitely return, I was very impressed! read more

Very easy! Called and made an appointment for the same day! I have never had to get anything smogged before so I was nervous. Silly I know. Let me tell you, Tim made it SO easy, it took not even 15 minutes and it was done. The lady at the desk who had also made me the appointment (didn't catch her name) she was so kind.

I've had 3 smog test done for our 2 vehicles and each time it has been the most pleasant experience. Both Timm and his assistant are professional, friendly and provide amazing service. The prices are very reasonable and so is the wait time each time I have booked an appointment and arrived 5-10 minutes before. I highly recommend The Smog Connection! read more

Been using this place for years now. I found them through Yelp and this place has been wonderful since day one. Bringing our cars in for a smog check isn't really anything we look forward to. Nothing about doing this is exciting. We have to take time out of our day, bring our car somewhere, and pay money. What about this is something we want to do? But, The Smog Connection makes that whole process super simple. I have been using Yelp to communicate with this company to set up appointments. So cool!!! They tell me what time to show up. I drive to the back of their place, park my car, bring in my paperwork and keys, while my paperwork is being processed, the car gets check. Less then 10 mins go by, my car is done, I pay, and leave. The paperwork goes to the DMV electronically. Done. Yeah!!! Seriously, about a 15min process. Painless. Thanks, Smog Connection. read more
