I finally had to get a smog check for the first time ever....not because I always buy new cars or drive electric, but because I've had such bad luck with cars that they usually never make it to the DMV smog-check stage. My boyfriend has been bringing his 2003 truck to this shop for years and recommended I come here. I pulled up right after opening on a Saturday morning, and the whole process was incredibly quick and efficient. Even with about three cars ahead of me, I was in and out in less than 30 minutes. By the time I left, there were about six people lined up waiting, so clearly I'm not the only one who knows this place is worth it. The owner was super friendly. We ended up chatting about baseball because I was wearing my red Dodger hat....which people constantly mistake for an Angels hat even though it clearly says LA. I just like red on me! That conversation alone made the experience even better. They also have a small waiting area inside decorated with old-school Yorba Linda photos and pictures, which gives the shop a cool local, family-owned feel. After how easy and pleasant everything was, I know this is my new go-to smog check spot. I'll definitely be recommending them to all my friends read more

I've never had to have a smog check before, but for the first time ever had to get one on my current vehicle. I came across this place due to the reviews on Yelp and so happy that I did! I called them to ask questions about the pricing and the wait time and the girl who answered the phone was so friendly and helpful. No appointment was necessary so I went in about an hour later and was given a 15-20 min ETA for everything. Sure enough, it was ready within the time promised. Everyone there was so nice and welcoming, and you can tell it's a great environment due to their camaraderie. Definitely recommend this place if you need a smog check! read more

Smog for DMV was performed. Engineer was honest and fast, and the price was reasonable compared to other locations.

Love this place. I always go there to get my Toyota smogged. The gentleman who has always worked on my vehicle told me that my windshield wipers were extremely old and damaged and that the line on my window was not dirt, but a deep scratch. I do not notice these things myself. He walked with me for a few yards to NEELS auto and explained the issue. NEELS, the owner put new wipers on immediately and what a difference. Great service and very pleasant. Highly impressed with SMOG TECH and NEELS. Angels looking out for me. read more

Needed a Smog Check at a STAR location and found they offered it. When I pulled up the parking lot was full and it looked super busy. Thankfully I went inside anyway and noticed they were a well oiled machine. Multiple cars were being tested and checked out quickly! At first, I was afraid I'd be stuck there forever, but it was quick, efficient, and painless!! Thank you so much!! read more

I needed to get my car smogged and was recommended by jiffy lube to come here. Upon arriving I handed my key over and went to wait in the seats spread out in their parking lot. It took around 35 minutes. The actual smog test took 10 minutes but there were maybe 3 people before me. It can get busy but the service is fast. I'd come back again. Good price and friendly staff. read more

Smog Tech gets pretty busy but they work fast. Average wait time is 30 minutes or less. They are friendly, fast and diligent in handling their work. It's not a fancy place but there is comfortable seating inside and outside the business. I came in to get a smog check for my vehicle to renew my car registration. I paid a total of $68. The inspection was $59.75 and the certificate fee was $8.25. They electronically send your smog check results to the DMV. read more

Easy in, easy out. My kind of place. I've always hated going to get my smog checked in the past, but I sure am glad I found this place. Very friendly, great customer service, and quick. Funny thing is, they even apologized for being short handed and for it taking so long! I thought they were super quick compared to other places. Highly recommend, and I'll definitely be back. read more

Spent about 45 minutes getting my car smogged. Was able to sit in office while work was being done. Reasonable prices and fast service!

Discrimination against older cars. I arrived at 8:30 AM on 10/06/2025. Parking lot was almost empty, (2 cars as I recall). I go into office and I'm told it would be an hour's wait. They finish the cars in the parking lot and then 3 other cars come in & they are serviced. I ask the office, "What's going on, I got here way before these other 3 cars that you just smog checked. They tell me that older cars take much longer to smog check and to keep their parking lot clear they will continue to do the newer cars first ignoring the order in which the cars came in. The tech, (probably owner), tells me to come back later. I come back at 0ne PM, same day. This time woman talks to me. "It's going to be at least an hour wait". I told her I was willing to pay more if my car took longer I just wanted to be treated equally to newer car owners. She says "We Don't do that", & would not schedule me in the order I drove up in. I asked, "Can I make an appointment? She says "We don't make appointments", and quite rudely too! She says, "I'm not changing my business because of you". She says come back Sunday, that's when we are the least busy. I'm 83 years old and not in great health, COPD and extreme abdominal pain due to "Scar tissue from a bad hernia operation" I can't sit for long periods. I tell her, "You put me behind 20 to 40 year olds with better health because my car is older? AT ANY RATE, THIS IS DISCRIMINATION AGAINST OLDER CARS & OLDER FOLKS!!! PS: I found another Test Only" 5 miles away and they made an appointment for me the following morning. read more

No appointments needed. Quick service that took maybe 15-20' on a Wednesday afternoon for $62. Can't complain. Would come here again.

Really poor customer service!!!!! There is a woman and man working there. They were SO rude and NOT friendly. Smog check went well, but will not be going back! read more

You know you picked a reasonable and reliable place to do a smog check for your car when it gets busy on a weekday afternoon. We weren't expecting to wait, but we didn't have to wait too long. The team was HUSTLING to get through the line of cars and they still had time to answer our questions and have a nice conversation. They have a small waiting room full of magazines and old classic photos of Yorba Linda. Or you can watch the team in action through a window. Great service and reasonable prices! I will be back! read more

Came here to get a smog check for my bf's truck and even though it was about to close in 30 minutes, they were able to take it. We didn't wait long at all, maybe only 10 minutes and it was done. Great and fast service. The waiting room was interesting too, all these old pictures of what Yorba Linda looked like and how it was. read more

I've been going here for years and have never had an issue. They are fast and friendly. In and out without a lot of noise.

Family run local business, efficient and fast! I was in/out during my work lunch break in around 15 minutes. Well deserved 5-star rating. I'm glad to have found this local spot (thank you Yelp!) and would recommend it to others who need smog service in the Placentia/Brea area. read more

Been going here for years. Usually in and out in 30-45 minutes. You can see them testing your vehicle from the waiting room. No cutting your sensor wire like the EconoLube&Tune just across the alley from them did to me. read more

Never ever ever again. This place is absolutely horrible. I called them to see if they would be able to smog my 1995 Jeep Wrangler and they said they had the equipment to do it. Perfect, drove all the way from Corona to Yorba Linda since they had a decent price and there machine was working, also had family in the area and the Jeep had been taken there before by another family member. Anyways. Arrive around 11 AM on a Tuesday, they took the paperwork and they said it would probably be around an hour/hour and a half as they were busy. Okay no problem. Went to lunch with some family, hung around for a bit waiting for a phone call saying the Jeep was done. Nothing. No phone call. Arrive back at 1 PM asking if the Jeep was done and some gentleman comes out (with attitude) and says they haven't even gotten to it yet and to just leave it and he will get it done. I ask how much longer? and he proceeds to just keep telling me to leave it and he will get it done. I don't have all day, you told me it would be an hour/hour and a half and it's now been two hours and you still aren't done? I then ask if he goes in order of arrival and he says it takes awhile for the older vehicles. That didn't answer my question at all. He states he's already done 40 vehicles in the time that I had my Jeep there, but my Jeep still isn't done?? And there definitely wasn't 40 vehicles in the parking lot/line to be smogged so he obviously didn't want to do my Jeep. Sounds to me like if you have an older vehicle it takes more effort to smog it and he just quickly does the newer vehicles as it takes less time. That's no way to run a business if you ask me. Will definitely take my business else where and will never recommend this shop to anyone. Ever. Gentleman was super rude. read more

Friendly service. The guy works fast and they do get busy. I'm in and out in about 15 minutes from the time he starts on my car. Don't come here at 8am on weekdays because there won't be anyone there. The guy arrives at 8:30am sharp on weekdays. The waiting area is fine. Seats, soda machine, what else do you need? read more

Great people who know their stuff! Nice family run business to patronize they do diesels as well

Thumbs down for Star Smog Check Station at 17035 Imperial in YL. Went there and saw many people waiting. I asked the woman working at the front desk how long the wait would be. She responded 45 minutes. When I asked her if she knew of another nearby smog station she responded in a very snippy voice, "you think I would tell you". My response was yes if you had good customer service. She stormed away from the counter. This company not only lost me as a customer today but forever read more

Yelp is wrong. It states it is open on Sundays. Waited and verified that it is not open on Sundays!!!
