Was treated very rudely by the attendant went to do a smog and first thing I was greeted with was "not going to happen!" If that's how they talk to customers no thanks! read more

Smog? New to the area, I wasn't exactly sure why my DMV registration renewal was requiring me to get a smog check. Regardless, after a few clicks on my local Nextdoor site, I came across Smog King. It's no wonder they came highly recommended by my neighbors! Made an appointment the same through their super easy to use website. I was greeted by Chris who walked me through the entire process. He was super informative and explained everything. All in all, I was in/out in 15 minutes. And yes, my car passed! Don't forget to get the $20 coupon on Yelp. read more

Very easy, and friendly. I walked in without an appointment today, and I was fit in when someone was late. Recommended by my mechanic, and they did not disappoint. The fact that they have appointments makes this a return destination for smogs for me. read more

I had a great experience at Smog King. The online appointment system was one of the smoothest to use and the customer service was amazing. Chris was professional and pleasant, taking care of my smog check quickly and sent me on my way with a smile on my face. Great place. read more

Robert was nice on the phone for appointment booking. Chris was professional, honest, and straight forward. Good smog check experience. I'll recommend Smog King to my friends. read more

All hail, local businesses! Smog King gets an A++ for excellent service, fast testing and fair pricing. Will be my go-to smog test location before I switch to EV vehicles :) read more

Fast and professional service at a good price and if you go on line to their website you can get a $20 coupon and schedule your smog service on line. read more

I use this location for both personal and company car smog requirements. Great service and fast. You can make appointments, but my last 2 times in I just walked in and was out in about 30 minutes. Chris helped both times and he was friendly and efficient. read more

I have been coming to Smog King San Ramon with my cars for years. I have always been satisfied with the service. This morning I went in for my appointment (on time). George was sitting in the lobby drinking coffee. He was so grumpy it was awkward. George said he was glad it was Friday (it was Thursday,his Friday) was the first thing out of his mouth. He acted like he had a backup of customers waiting for him at his high pressure job. I asked him a question and he grumbled and couldn't be bothered. He was the same when doing the paperwork to finish. I won't be going back there again. He needs a new job at a different company. What happened to the other man that was so pleasant all these years? If you just want fast service go ahead. I think being pleasant to customers shouldn't pain a business. There are lots of smog shops ! read more

Went here for a smog check. There was only one guy working there but he was great. He handled the check out as well as performing the smog check. Very efficient. Would highly recommend this place. read more

This is by far the best place to have your car smogged.. They are efficient, friendly, very professional... I will refer Smog King to everyone I know.. read more

Great service and super fast, but I felt awkward using their portable white cash register because it asks you for a tip. Getting a vehicle smogged is pricey as is and it took under 10 minutes but I felt obligated to tip because it suggests 15%+ gratuities. I wasn't going to be that jerk who said no tip when prompted and standing in front of an employee while they watch me use the register. At the same time...it's a smog shop. They're getting paid a decent hourly wage, why am I being asked to tip? I won't come back because of it.M unfortunately. just hate that pressure for an industry that doesn't typically ask for tips. read more

Here's my tip for getting your smog cert. before you head down to drop your $$$ use a OFBII reader to check your car first. Smog King did a solid job quick and easy. read more

If you need a quick and efficient smog check, this is the place to go. The price is reasonable and the service is fast. No problems, just a great deal. I suggest making an appointment online for priority service, but appointments aren't required. read more

Honest, fast and friendly service. The tech explained the process and help smog my van and it passed. He was upfront with pricing and doesn't do tricks like some places. Highly recommended. Thanks read more

I think Smog King in San Ramon is the ONLY place I would ever go for this service. They are honest, quick and extremely good and nice

I used their service two years ago and didn't have any problems. Recently, I brought one of my cars back to get re-tested. The guy behind the counter was rude and had an attitude. I don't ask much from commodity business's other than being polite and providing the absolute minimum customer service. I definitely didn't feel that I got even that. Oh well ... good thing there is a Smog Test center on every street corner. read more

Time again to do "...the smog routine..." No coupons handy so I did a Google Search. I contacted this local shop listed on YELP! The gentleman answering the phone said he would perform the service for $98; after a minute he said he could do it for $78. Still seemed too high. Eventually went to Walnut Creek for $37 ... worth the trip. This review has nothing to do with the quality of work performed or the customer service attitudes as noted in antoher review. My interaction only related to the pricing for a simple service available just about anywhere. It pays to shop around! read more

Excellent service and great price! With an appointment, it took 10 minutes. Had a $20 coupon so cost was $68. What a deal!

This location is conveniently right off the freeway and has plenty of parking. I Came here without an appointment and was seen right away. My smog service was done in less than 15 minutes and was less expensive than the other two locations by me. I Highly recommend. read more

After the Discount Smog Test Station ignored the engine light in my car so that they could charge me for a smog test KNOWING the car would fail, I brought the car to this place. As I just moved here from out of state and never had a problem smogging the car before, I didn't know the rule about the engine light. The last place hooked the car up anyway and then charged me 109 dollars for an aborted test. Smog King got into my car, saw the light, then got out to explain why it would be a ripoff for me to have the car smog tested, as it was an automatic fail. He didn't just hook the car up, charge me, then tell me it failed. When I saw this kind of customer service and integrity, I brought my other car down and had him test it. In and out in ten minutes. I'll go there as long as I live in the area. read more

Fantastic service, quick turnaround, great attitude. My usual repair shop was unable to Smog test a 6 cylinder boxer engine so I had to quickly find an alternative. These guys were great, they also send existing customers a reminder money-saving "coupon" prior to your next smog - so keep an eye on the mail and don't throw that coupon away :) read more

I think I was maybe here less than 10 minutes, super quick, efficient and friendly! Would highly recommend this business.

Very rude person at the front desk. There is too much competition in the valley for me to spend my money at a location with rude employees. I walked out and won't be going back here! read more

I have used their services for many years. No nonsense speedy smog testing In less than 20 minutes with appointment

Came by around lunch time to take my boyfriend who works next door to lunch. He wasn't quite ready and I'd just gotten the paperwork from the dmv saying I needed to get my car smogged so I figured I might as well try this place out. The guy was very friendly. He promised to have my car done in 10-15 minutes. About 5 minutes later it was already done. I'll definitely come back next time I need my car smogged read more

Nobody likes getting their car smogged. It's just a fact of life. However, if you get the extra pleasure of having to go to a Test Only facility, that just adds to the hassle. But, the folks at Smog King make it pretty easy. I was able to book an appointment online and print out a coupon right from their website. The day of the smog check, I drove the car around for a little while, showed up on time and they were ready for me. The guy working there was friendly and helpful in getting the paperwork filled out. And then the testing was completed in about 20 minutes. It was very painless and easy. Heck, they even have free wifi in the waiting room. After the test was over, he explained the results to me even though I passed. I appreciated that. All in all, it was a good experience. Will I be back? Sure the next time the DMV tells me to. read more

I am here right now! The owner saw me sitting in my car... 30 minutes before opening... came up to my car and asked if I was waiting for him. I said yes and I know that I'm early. The guy says, "Come on in... I can start early... I would only be drinking more coffee waiting for 8 o'clock to come around." Done in 14 minutes!!!!! THAT's THE KIND OF SERVICE I'm TALKING ABOUT!!!!!! What a great guy!!!!! 10 Stars Baby!!!!!!! read more

Recently purchased a car from someone on craigslist and they didn't do the smog that they were suppose to do. So I called around to a bunch of places. Then called Smog King he told me $98 and I mentioned that it was higher then what another guy told me. He was able to match the price no questions asked. Update: Noticed a comment from the owner and decided to make it a five star from a four star. The fact that the owner of the business, or even someone that works there, cares enough to read and comment on my review will definitely be getting my business again. read more

Smog King is professional, fast, polite, and located conveniently. They have a comfortable waiting area. Based on my experience I will use them again for my next smog test. read more

Great customer service! Made appt and rolled right in. Highly recommend! Have had bad experiences elsewhere, we will only be coming here in the future. read more

I called in the morning, got an appointment at 11:00 and was out in under a half hour. Good customer service and I appreciate them accepting a coupon from a competitor. Please call first and confirm with them before showing up with a coupon that is not from a nearby smog facility. read more

After being turned away from the shop that has had my business for probably 20 years because they claimed they were unable to get either one of their chassis dynos repaired, I opted for Smog King. Friendly, courteous, and careful around my car. Even offered me a $20.00 off coupon. They have my business going forward. Great job, great service! read more

I had a bad experience and wrote my first Yelp review. Owner contacted me and apologized and gave a free smog test. Customer service was great. They really made up for it. I'm sure it was a one off experience. 4 stars because I had to deal with the bad experience initially. read more

Extremely friendly service as well as very quick! I was in and out in less than 20 minutes. I made an appointment, so that probably helped, however other yelpers have said they didn't have an appointment and still didn't have to wait long. He told me about his $20 online coupon when I called, which I printed out and brought with me, so all said and done it was $78 including the certificate. Would come back here without hesitation - great customer service! read more

Chris was fast and professional. In and out in no time. Pleasent guy. Thanks Smog King

Doesn't get any simpler or faster than this place! The owner is super flexible. I was in and out in probably 20 minutes tops.

Another year, another excellent experience with Smog King. They are fast, polite, fast and fast. 20 minutes from my office to being done with the test, and 15 of those minutes were traffic on SRV Blvd... read more

Friendly service, but expensive, gave me a 30$ discount, but still decided to go somewhere else because it was cheaper. If you have the Xtra money to spend go ahead read more

Technician was very friendly and efficient, accepted my coupon and told me it would be about 15 minutes. Ten minutes later I was settling up and on my way. Highly recommended! read more
