Horizon Smog Brentwood

Great place to get your smog done. I've been coming here for years. The staff are very knowledgeable and friendly and they get you in and out!

I had a decent experience here. The staff wasn't overly friendly but they get the job done and honestly who has time for pleasantries when it's 95 degrees and you're dealing with an endless line of people coming in for smog tests. I can imagine it's no fun not to pass and that can probably lead to some less-than-polite interactions with customers. Mine passed and they made sure to get the info over to the DMV right away so I could finish my registration. They still honor the online coupon so make sure to get it and save it on your phone before you go in-show it up front. I went on a weekday afternoon and it was a 90 minute wait, which was a bit surprising. Maybe, making an appointment is the way to go? Anyway, I won't have to come back for another 2 years but would use them again,

Once again I went to them to get my car smog checked. Last time I went was 2 years ago; and as back then, they did a great job! Convenient, appointments not needed and in a normal year, you can walk around town if there is a wait. This year, I was in and out in 15 minutes. Professional, friendly and they always have coupons online.

Went to have a smog test done and was in and out within 20 minutes. I would recommend Horizon Smog to anyone who needs test done. Great job! Thank you Horizon Smog.

Best local certified smog check, imo.

Lee is just a great person. Very professional took me in very fast. He was very respectful and a good human being. I would recommend this place if you are looking for smog. Thank you very much Lee and have a awesome weekend.

UPDATE Aug 2023 !!!! MUST have new owners. I showed up no appointment, The guy was nice & polite, he put me in line, (i was the 4th car to be next), told me about 45 mins, SO i left WITH my car and he called my cell phone when it was my turn for a smog, i can back & was out of there in 15 mins flat. Outstanding service was not even expecting all that. I’m so glad i went there, i own 3 cars & now i know where to go.

Quick and easy, no appointment necessary, and great price. Found a coupon online, printed it out, walked right in, and 20 minutes later I was on my way. Every other place I called wanted around $30 more for a smog check and wanted me to make an appointment. No thank you, I’ll stick to Horizon Smog!

They have always been fast and good price.

Had a smog check and failed the first one due to computer not having enough miles after dead battery. The employee let me come back the same day after driving 50 miles and told me to keep it at 60 mph. Worked likes charm I passed and he did it right before closing.

Great quality service. Very professional and didn't take long even though it's Hella hot out today! Great place to get your smog. Will be back next time around.

Great service! Great price! The technician was professional and got me in and out quickly.

If you have an older car that needs to get smoged this is the place to go I went to 5 different smog shops and all there equipment was broke Horizon smog in Brentwood fast friendly terrific service

Great experience! The owner/smog tech was professional, friendly and informative. After being a customer at Fire House Smog in Antioch for over a decade I will make Horizon my new go to smog shop.

I called a few times with some questions the day before I went to get my car smogged, but all of my calls were not answered. I went the following day around 11am and everything was quick and easy. I was in and out within 20 minutes for my 2007 RX400H smog. I paid a little more than expected ($78) but nothing too crazy! Everything passed, Decent experience nothing too bad to complain about.
