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!

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.

Been coming here for years! Always friendly staff, quick in and out. Coupon is always a plus

Extremely prompt and thorough!

This is a good shop. I was really pleased with the service and treatment. I felt they value each customer. I recomend checking them out. Even though my car didn't pass, I feel the tech cared about me and was really fair about things. If you agree? Please, hit helpful.

Great shop! Good price. I fux with them!

Best local certified smog check, imo.

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,

Just dropped in without appointment, Lee was friendly, quick and professional. Had smog cert within 15 minutes. I'll be back next time I need a smog certificate.

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.

Very fast and quick service. I was in and out in about 15-20 minutes. The gentleman at the desk was very friendly and professional in his interaction. Be sure to mention the coupon to get the best price available if you have a sedan or coupe.

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

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.

I drove up and asked if he could do the smog and he said yes. I gave him my keys and got my kids out of the car and he said that there was a park right across the street I could take my kids to while he smogged my vehicle! It was awesome. I could still see my vehicle from the park! Great fast service! Definitely recommend and if you have little ones, take them to the park or the ice cream place across the street 😌

Brought my car in on Saturday morning without an appointment and they got me in right away and had my smog check done in less than 30 minutes. I was the first one there but they are fast and efficient.
