I used a different shop in Vista a couple of times when we moved here & the guy there wasn't helpful or friendly so I found this place & its been great! 2nd time here & I forgot the DMV notice this time which makes it easier for him but he said no problem & was very pleasant about it. Fast, affordable (they have an online coupon) & friendly - thanks! read more

I went to get a smog for a 1991 Jeep and it didn't pass. I had to pay ( which is fine) but if I don't come back within 30 days, I have to pay again. This isn't helpful because now I have to get it fixed and how am I going to get it back there within 30 days when the part isn't available because it's an old vehicle. So I don't recommend this shop for older vehicles. read more

Great place and open Sundays! The service is quick and friendly! I highly recommend this place!

Quick and trustworthy smog service. They took my coupon and I am very happy doing business at A Smog.

Service is always quick and reliable. I've always felt like I got honest service. Never had to wait very long

Needed a smog check in order to renew my registration. Process was quick and easy! Arrived around 8:10 on a Saturday morning and was leaving around 8:40. Henry was friendly, polite, and professional. Highly recommend! read more

Henry is the owner and operator of this business and very professional, friendly and bilingual (English/Spanish). There was a small wait but he does have a waiting room too. And there is dedicated parking for his shop. I came for a smog check and it was done in a timely manner. The price posted includes the certificate. The price was fair and even a few dollars less than most places I researched. But if you go to Henry's website for A Smog Testing a coupon is available which makes it an even better value. He also provides other DMV services for a nominal fee. read more

Fast , easy and cheap. Nice guy took me with no appt. Coupon saves you $10 so it was only $38 + dollars. Way cheaper than the 60 - 65 dollars quoted else where. Thank you read more

So happy when I called at 3:45pm on a Saturday to see if they were still open and can test my car in the next half hour when I get there. He was so accommodating and friendly and said to come right in because they close at 5:00pm and there's enough time. He took me in right away with no wait and was in and out in 15 mins. The coupon helped and he was kind enough to honor it even if I couldn't print it out. I highly recommend this place and calling first helps. read more

I have a 2019 Prius. I didn't need an appointment. In and out below 30 minutes. Cost escalate as the models get older, but that is reasonable. read more

Easy in, easy out. Arrived before opening, first in, first out. Had breakfast across the street, walked back, smog completed.

Great fast and friendly service and graciously accepted their coupon printed on their website today without any upsells or double talk other local smog test stations around Vista are doing currently 10/22/2025. No up charges for SUV. best price around Vista oceanside. Straight forward, great place. Thank you A Smog Testing and Henry... read more

Always great service quick and convenient . My go to smog service provider. With great competitive pricing.

They refused to smog my 2014 Porsche Cayman because the guy couldn't figure out how to do a visual inspection on my emissions component due to the mid-engine. Never had a problem before. I went to another smog shop and got my car smogged with no problem. I asked the guy there about it, and he said not true that you have to access the engine in all cases, and that he could see everything he needed to know by connecting the OBDII scanner. read more

Great job in getting this done on a hot day! Needed a snag test for car registration renewal. Great price, great service, definitely recommend this place! read more

Second time here, first was my Tacoma, and now my CT 200h. Service is very professional and efficient. You're in and out very quickly without being overcharged with weird fees. I was quoted almost double in some places in Oceanside. So worth the drive up here, and they're open on weekends! read more

This is the best price for a smog and the best part is that I didn't have to haggle or bring in a coupon. I called in to find out if I could walk in and they said to come on in and that they had 2 cars ahead of me. Waited in the lobby and was out in no time. I will definitely be coming back. read more

Great service, quick simple, and very affordable . Didn't have to wait too long. I used the coupon that was sent to me through email. All you gotta do is click on the link show the coupon to the attendant and you're all set bring cash if you don't wanna pay the 4% extra fee for using credit card. read more

Went in on a Sunday morning and I was out of there in less than 15min. Go early like I didn't and you'll save a lot of time

Very nice place, was provided fast and friendly service. I came in with a coupon from their website and was in and out in 10-15 minutes. I would recommend this smog shop as the person helping me explained everything and was very helpful. Also this was the most affordable smog shop I could find in the area (with our without the coupon surprisingly). read more

An honest man. I was referred by a friend and he is an honest kind person gave me tips errors my car could've had. I've returned and will return again read more

Was in and out of there in 10 minutes. Probably less. Couldn't ask for better service and they were quick and to the point. I'd happily bring a car here whenever I need a smog. Price was great and couldn't beat it with the coupon. read more

Great service, I would recommend this smog station for Sprinter vans. Henry was very friendly and efficient.

Great price and quick service. Owner was kind of enough to mention online coupon for better savings.

Such a good experience with getting my smog test. They replied right away in Yelp regarding their pricing which was so affordable. The staff were so friendly and made the process so easy and I felt very comfortable. read more

Henry was great. I was refused from another location and he took me in right away even though it was close to his closing. He waited for me to get there and gave me the smog check I needed. Thank you so much for the help and I will be using your service next time I need it. Recommend him to anyone needing a smog check. read more

A Smog Testing was great. Henry was super quick with his response on yelp. I was able to walk in and the smog test was very fast! Thank you again so much! read more

Received bad service. The guy literally nitpicked my car about non-existing issues and claimed they couldn't do the smog check. Don't bother coming here. read more

We found this company utilizing Yelp...We were not disappointed! Henry was friendly, fast, & professional. Used a coupon from their website & this was by far the most reasonable cost for SMOG! We had our 2005 Chevy Uplander van smog checked & then brought our daughters car in. We will continue to use this shop! read more
