Had to get a smog check, forgot until the last minute. Used the Yelp app for services to check locations and pricing. Star got back to me fast with the price and I had a reservation for the same day. Drove down three hours later, and it took longer to park and do the paperwork than it did for me to wait for the smog check and Star certification. Amazing help, fast, nice receptionist and tech. Cheap af and great work! read more

Always fast & convenient. And don't forget about advertised coupons. I've been going here for many years - never disappoint. read more

Seriously, that front desk interaction was absolutely atrocious. Customer service really starts with the person checking you in; you are the face of the entire experience, you know? Making a good first impression is so important, and it sets the whole tone. When that goes poorly, it's hard to recover from. It leaves you feeling frustrated right from the get-go. I just wish there was more awareness about how critical that initial contact is. A little politeness can go such a long way. It was quite an observation to witness the contrast in customer service received. While interactions with other patrons appeared consistently pleasant and professional, my own experience was notably different. The demeanor exhibited towards me was characterized by a distinct lack of warmth. Furthermore, the tone of the responses I received was quite abrupt. This disparity in service quality was quite unexpected and frankly, disappointing. It is generally anticipated that all customers would be treated with the same level of courtesy and respect. Such a noticeable difference in approach raises questions about the consistency of service delivery. One would hope for a more uniformly positive experience across all interactions. *warning Front desk lacks customer services unless you are man! read more

Had an excellent experience with my Smog test on 7/21/26 at Star Smog in Walnut Creek. The technician was very experienced and prompt. The receptionist/cashier was very helpful and they have a comfortable waiting room. The rates were also reasonable. Dusan P. read more

I came in at 9:30 on a Thursday for a smog check. The place is clean and in a pretty nice area next to a repair shop and a tire shop. Plenty of parking. 10 minutes later, smog was done! Awesome. read more

Updating my most recent review to 1 star. After my first review of this smog shop the office lady reached out. She first called my husband and he called me asking to call her as she wanted to better understand my rating. When I called her an hour later she told me she would call me back that day from her personal phone as the phone she was on wasn't clear. Well she never called me back, and that was 3 days ago. Don't waste your time or money here! read more

These people will have a coupon for a smog check only to charge extra just because the car sits higher. That is unfair... DO NOT EVER DO BUSINESS with these people!! read more

Their service is fast and friendly, also open on Saturday, no appt. necessary. They have online coupons, with a look.

Made an appointment the prior day. Got there 5 minutes early and was out in 20 minutes. Painless, which is what you want for a smog test. My only complaint is that they need more parking! read more

The service here was AWESOME, not only did they take me earlier than my scheduled appointment time, but Sophia was very helpful explaining the pricing & timing (I'm just a girl) , and I was out of there in less than 20 minutes! Referred all my friends and family to this location! Easiest smog appointment I ever had. read more

2 years I went to star smog. I was overly charged $20. he didn't explain. Now they give you an invoice to look at and sign. Advice - ask lots of questions and make sure you get an invoice and see it up front so they don't over charge you what you don't need. [[HIGHLIGHT]]You and your employee harassed me for 2 days to change or take down the review. It was so disrespectful.[[ENDHIGHLIGHT]] And no you are not correct about the 2024 charge. he never showed me the amount and over charged me. read more

[[HIGHLIGHT]]Made an appointment and it was super fast and easy.[[ENDHIGHLIGHT]] And they had the England/Norway game on.

One of the few star smog stations in the area. Went to a few others, that weren't, so don't waste your time and just go here. They have an indoor waiting area which is very convenient. Didn't wait very long and was finished pretty quickly. Will definitely continue coming here in the future as my go to smog station. [[HIGHLIGHT]]Very welcoming receptionist Rida, very nice[[ENDHIGHLIGHT]] read more

Very quick process, competitive price, excellent customer service. I highly recommend Star Smog!

I took my 2012 Audi for a smog test there because it required a Star certified station. The tech took 5 minutes to find out there was a code that didn't show up on the dash lights, it needs a oxygen sensor, they charged me $107, which I questioned as being out of line, then they want to charge me another $39.95 to recheck when the car is repaired. [[HIGHLIGHT]]I questioned that fee to the manager Rita, and she said she would wave the recheck fee if she was there.[[ENDHIGHLIGHT]] I will go back after the repair for a recheck and see what they try and charge me, I will follow up with my review after the car is smogged. read more

Quick, professional, and easy experience. Sophia was friendly and helpful. I would recommend Star Smog to others. read more

Service was great. Service is still pricey with the coupon but they were quick and efficient.

They were fast, friendly & reasonably priced. They also will directly submit your Smog Report to the DMV before you even leave.

Quick and easy service. Was able to get it done the someday that I received a quote. The cost was the same as what I was quoted on yelp. No switch and bait. But do read the quote carefully, since cost differ depend on your vehicle for smog check read more

I was selling a car and Star Smog seemed to be the best price if you printed out a coupon. The challenge is finding straight forward pricing. I didn't notice my registration noted Star Smog required. A lot of smog stations add an additional fee to the price. A Star Smog station doesn't do any additional tests, it is just a designation that they have been qualified to add. The pricing for the smog test and certificate was pretty good with a coupon but there was an add on of $20 for Star certification. KS Smog in San Leandro has a flat testing fee and the standard certificate charge with no add ons. I didn't have more time to go to KS Smog so Star Smog with the add on was the most convenient locally. I forgot to take pictures but you can find them on Yelp to click on their website with pricing and tests performed. Also, if you do an internet search for Star Smog coupons you will find different coupons that you can print out which they honor. They were pretty quick and popular. I got lucky and walked right in but there were 4 customers that came in after me. The elapsed time there to check-in, test and wait to pay was 30 minutes. It would have been faster but the guy at the desk had to check-in the other customers. Helpful and friendly too. Read the web site carefully so you are aware of the different charges you might incur in addition to the standard test price and certificate price. read more
