Came here early Saturday around 9am for a smog check. It's on a corner of a cross street so it's not hard to miss. The front of the shop had a lot of space to park. Their garage is small though only can fit 2 cars at a time. There is some chairs where you can sit and they had a huge fan in the lobby for a hot day. Song was very efficient and professional. He took us in right away and we only waited 10-15 mins for the smog check. He was also very nice and made it affordable. I would definitely recommend this shop for a smog check. read more

Came in today for a smog inspection and the wait time was about 45 minutes long. They have limited sittings available and it was quite hot outside with some shades. The price has gone up tremendously. I came in before one customer and turned in my keys to the technician already, but they skipped me and helped that other customer before me. Not sure how they keep track of their clients, but if you don't mind getting cut in line for service or the price then this place is okay. read more

Monster Smog - Smog masters - Smog Check Stations Near Me - Fresno, California

Absolutely love this place!! Waited till the last minute but Monster Smog had me in and out in less than 30 minutes. It was hot out and they had cold water and a portable air conditioner to help. Customer for life!! read more

First time here and I was nervous as it looks a bit...abandoned. FABULOUS SERVICE! Walked into the small waiting area and within seconds I was greeted and my keys collected (park in the back or the front...it doesn't matter). A minute later I filled out a form and it took about 20 minutes and there was at least 2 people before me. Price was $45 with certificate and the smog tech Mr. Pong was very nice and quick as well as helping others who had issues with their past smogs. I will definitely come back again! They do close at 5:00pm during the week so get over there asap and no appointment necessary. Seriously great experience all around! Very, very happy BTW I am in Fresno, CA. Not sure why it says I am in San Francisco, CA read more

1. Walk ins welcomed 2. Friendly customer service 3. FAST!!!! $45 Smog and certificate read more

a great price for smog and friendly service. they got the smog done quickly and I did not have to wait long. Definitely would recommend this place! read more

Had 2 good experience here than the last two was terrible. I was cheated into getting a smog. Dont come here. Never went back.

First time here. I love how they're fast. Check in was fast. My car was done under 20 min or so. Overall, it was a pleasant experience. Will definitely be recommending my family and friends here. read more

Great service. Great customer services. Recommend to everyone. Every year I'm back to this location to get my smog done.

Things to Note: Test Only Center. Looks like they will work Sundays if you schedule an appointment. This Smog station was converted from a gas station and still is like 75% pavement, so easy to park. Besides those special notes it's all the normal things you expect from a smog station fast, easy and cheap. I also talked to the owner for a while. A nice guy. So a solid 4 starts. read more

Great Customer service, fast, reliable. My family and I always come here whenever we need our cars smogged. prices are very reasonable.

First time customer. Walked in and was helped immediately. The manager was friendly and professional (and wearing a mask!). 10 minutes later the smog inspection was completed and I had one more todo checked off my list for the day. Recommended! read more

Took my car in today to get a smog check and was in and out within 25 minutes. As many have said, they are SUPER fast and efficient. The price is also fair. $45 out the door! Don't be intimidated by their store front! I almost missed this place when driving up. It looks like a condemned building, but they get the job done with great customer service. It was really hot today and their waiting room has no AC. They had a huge portable unit in there, but it didn't help much. It felt better outside! So be prepared for that if you're going during the Summer! Good thing, they are quick! No issues! I recommend these guys to any one who needs a smog check. read more

OMG! Took my beater silverado here and was crossing my fingers to smog it. Boy, did they smog it fast! Sorry Jimmy Johns and hello ladies, there's a new minute man in town. Luckily my intermittent CEL didn't go off for that common GM dreaded P1516. The suspense would've bought me new pair of dungarees if the wait was any longer or the code might've gone off; and thankfully the leaky head gasket didn't throw a code. With such a wonderful noncompetitive experience here, I had to roll my beater nissan titan down the street to smog here and it also passed with flying colors, despite the leaky cracked headers, but that's evidently not a problem. read more

Reasonable price. Easy to talk to. Professional. Lee was especially professional which made me very happy. This is a small, it looks like family run business, so very happy to see they took professionalism seriously. They were fast and efficient and I was in and out of there. Very pleasant experience. read more

Went there today 11/29/22 for a smog, everything was fine until I got my keys back. The guy that took my car to test it broke the key to the car and gave it to his sister whose was doing the paper work while he ran to the other side and just sat there hoping I wouldn't notice anything wrong with it. Well it worked until I got in my car and saw that my key was almost falling apart. Not even a sorry or hey I broke your key. Worst service I've ever experienced if I can give it a 0 star it would be 000 stars read more

I came to this Smog place after my go to auto shop had had their certification lapse.

Hell yeah! that's what I am talking about. I called the guys again to see if they will honor the old pricing and he said yes. When I got there it took them less than 10 minutes to finish smog and get me out of the door. I think they deserve a 2nd chance. Keep up the good work Monster smog. read more

I was given a recommendation to try this smog shop. They offered great customer service. They were super fast. And I was in and out before I even knew it! I will definitely be referring my friends here. read more

Fast and Easy! I brought a book with me to read while they Smog'ed my truck, and I barely had a chance to crack it open. Staff is friendly and professional. It was also nice that they were open. I tried three other Smog places before them that were all closed, on a Saturday morning. I will definitely refer them to friends and return there with my other vehicles. read more

Smog 2 Vehicles Quick and fast! both Passed. Excellent customer service. Will definitely come again.

Best smog experience! This place was a bit off my normal path but worth the drive. Staffed by a trio of nice, friendly guys, the service was quick and efficient. We were in and out -- and we passed-- in 10 minutes. I'd recommend it in a heartbeat. read more

Walked in on a Saturday afternoon. No appointment was necessary. They were super nice. Worked on our car right away. And we were in and out in 15 minutes. Definitely taking our cars here going forward. read more

I had a 1995 Mazda (pre-OBD2) and every smog shop in town wanted over $60 to smog test it. I called Monster Smog and the manager, Song, beat that price. I checked the reviews and I knew this was the place to go. Song was very professional and knowledgeable. Definitely a "Grade A" experience. read more

Looks can be deceiving! Nothing fancy about this station but the guys are very personable and friendly. Most smog stations give me grief when I ask for a test on my 1979 Plymouth Volare but these guys didn't even flinch. $45 out the door, and done in 20 minutes on a Saturday! Would recommend. read more

I called around for pricing and they had the lowest. Its just a test, they dont do anything else other than send it to the dmv. But they got my car in and out super fast. read more

I had a friend recommend this shop to me. Smogged my car and my wifes car at this location. Fast and friendly service. No BS. Inside the shop is a bit on the small side. The prices are comparable to other shops. It's easy to pull in and pull out. The good customer service that I got from Monster Smog is why I will keep coming back here every 2 years. Thanks Monster Smog! read more
