i am very disappointed with the service i received at California smog. I brought my truck in for a routine diesel inspection, and the technician refused to test it based on completely incorrect assumptions. He claimed that my downpipe, intercooler, and wastegate were aftermarket, even though all components are 100% factory stock. He insisted that these parts required CARB EO numbers, despite the fact that they are original ford equipment. the only modification on my exhaust is a 4-inch system after the catalytic converter, which is fully legal in California and requires no EO number. This is easy to verify by simply looking under the truck and comparing the larger aftermarket tail section to the stock unmodified 3.5 inch factory downpipe. The technician did not take the time to properly verify anything. he was dismissive, rushed, and unwilling to listen or provide clear information. Instead of performing an accurate visual inspection, he refused the test. To be sure i went to another certified star smog station the same day. The technician there immediately recognized all of my components as stock, knew the correct regulations and passed my truck with flying colors . This experience shows lack of training, knowledge and professionalism at this location. Costumers rely on smog shops to understand regulations and inspect vehicles accurately. Unfortunetly, that did not happen when I went to California Smog. read more

In and out within 15 minutes ( I did schedule an appointment) Friendly locally owned business operated with efficiency read more

We use this service often but an appointment is recommended as they can get very busy. The process is quick an easy.

Friendly, quick service and no surprises. I needed an appointment because my 4runner is pre-2000, but that is standard. 5 stars!

The BEST smog inspection station in the greater Auburn area! The owners, Liz and Tom, are spectacular. My 2015 Subaru passed with flying colors...and the appointment was completed in less time than it takes to drink a cold latte! I highly recommend California Smog! read more

I went there talked to the owner he scaned my Acura told me I needed o2sensor.Went put new sensor in then cleared the code.You have to drive it too erase 100 miles. Took it back to California smog and it passed Yay!!. read more

They are the best in the area! They lived up to the reputation. Can be busy at times but even without an appointment they'll fit you in! Thanks. read more

For years this shop, a family owned business, has always been very professional, kind, on time, honest, etc. I have probably used them more than 10 times. Today, I brought a car in that we had a lot of work done on it. Because the previous codes were cleared I need to drive the vehicle more to bring the electrical system up to date for the smog. No charge. He kindly instructed how t odd what I needed and shared a website for my vehicle so I could get it going. These people are true professionals. I trust them completely. read more

These guys were great and got me in and out the day before my smog was due. They were very busy but managed to find a spot for me an hour later and I came back it was quick and painless. They were also very nice. Will definitely be back. Thanks! read more

They did a great job, were very polite, and everything went smooth on my smog check. First time here, they were great.

Professional quality service. They work fast and are a fair price. I definitely recommend!

Fair price, fast service, courteous staff, convenient location. I was in and out in 20 minutes with my smog certificate - which had also been transmitted to the DMV. The only problem I encountered was Waze taking me the wrong way. Not the fault of California Smog! read more

Very efficient. I made an appointment and was done in 20 minutes. Thankfully my 2013 Nissan passed! The service was great and very friendly. What more can you want? I would recommend California Smog as a go to place. read more

I have never had such a delightful experience with smog checked places in Southern California, so when I checked reviews online for smog check places, California Smog had a very good amount of good reviews which had impressed me due to my many horrible experiences in Southern California where my car failed the tests, then I was informed of the necessary mechanical work that resulted in costing me hundreds of dollars. I want this known, when your car fails a smog test, it usually cost hundreds to have repairs, which makes me curious as to how truly honest are some of the smog test shops. Anyway, I'm impressed with the mechanic and and his wife whom have shown professionalism, honesty, and great service at a reasonable price. read more

I took my truck to California Smog today. I've never been there before and was impressed how friendly and professional the front desk employee was. They had my truck in and out in about 20 minutes. The whole visit was about 30 minutes and the price of the smog was fair. We will be using California Smog again in the future! read more

This place is amazing! They are so friendly and allow appointments. They are quick and much cheaper than everywhere else- I highly recommend! read more

Just as the reviewer said on Aug. 1, we would not have gone if we'd known about their anti-mask, disrespectful stance. A sign on the door basically said, we posted this sign about masks because the governor says we have to, but if you don't want to wear them, that's ok. NOT ONE SINGLE customer I saw was wearing one or even tried to pretend. Although the male owner DID pull a bandana up on his face (likely because I was wearing one), the woman didn't even try. plus I saw no evidence of hand sanitation, pens were re-used, and she just touched everything from everybody with no effort to try to sanitize between customers. We were so utterly shocked and appalled that, as the prior reviewer had said, if I hadn't planned this into my day I would have seriously just walked away -- after telling them why. DO NOT GO HERE if you care about the state of the world. We are disappointed because their service has always been so great and they have been so nice. I am saddened. read more

I wouldn't go anywhere else. They get you in and out fast and the price is right. Very grateful for there expertise. I highly recommend this business. read more

I would recommend and return. I walked in at noon and was given an estimate that my car would be tested in 40 minutes. I left to run a few errands, came back in 35 minutes and they took my car in to test immediately. In 9 minutes my car was complete, under the time I expected. Super easy, affordable and professional with great customer service. Thank you! read more

The friendliest hometown smog shop. Best to call ahead to get idea on a wait or appointment if needed. Always fair priced and honest smog shop. read more

Sometimes in life you pay for what you get. Is this the cheapest place you can get a smog? No. Is this a place where you know your car will get treated right, no games will be played, and the technician will listen and give you advice on concerns you may have? Absolutely yes. This place is awesome and I take all my cars here now because I support this business. They are super responsive and respectful when I have concerns or issues and do their best to help everyone get their smog done quickly and efficiently. They work hard here and have worked with me if I had concerns about one of my cars and helping me squeeze into the schedule if I'm pressed for time. Both of which they don't have to do if they don't feel like it. If you value a good business I would start taking your cars here and help keep their business up and running! They are usually busy so that's another good indication that what they are doing is noticed! read more
