Great service! I needed a smog check for my work truck and found this place tucked away behind the Chevron on the corner. The service was so quick and easy that I brought my car as well! Mr. Lee had me in and out in about 15 minutes both times. I highly recommend Allen Smog! read more

Hope has been restored in humans again. My mom told me about a small smog check place...nice and honest man. She said it's difficult to find. A bit hidden. It's a small building. He's been here since 1998. Nicest guy. No wait. Yay! read more

Where do I start? Please read until the end. My family and I moved to LA in 2009, and we've been taking our cars to In & Out Smog Test Only Center for many years for polite, very quick and good price smog check especially with their $10 off/25% off discount offer. I was happy to be their loyal repeating customer for years but things changed quite bit a few days ago. My 23 years old car started to show some wear and tear and I've been dealing with the strange issue with my fuel cap that doesn't get tightened anymore. A few years ago, the engine + 2 other lights came on so I immediately took my car to my mechanic. He identified that it was little fuel evaporation fumes detected near the gas cap. Clearing the code, cleaning the area, and changing the gasket of OEM cap didn't help and the engine lights kept coming back typically a week after cleared or when I pump. It was my experiment to use the new gasket only on my old OEM cap because it can be just a worn gasket, besides the new cap from Amazon didn't fit well. This minor annoyance now became a big issue because DMV registration this year required a smog check!!! Even I knew Engine light = No Smog Check. I decided to go check and see how In & Out Smog Test Only Center can help to test and pass. I explained the situation, but they only scared me away by saying the current condition of my car with the lights on has no chance for passing the test and even if no pass, they still charge $60. They suggested to do a smoke test with my mechanic to identify the location of the problem and fix it before Smog check..., they said it's $169 for a smoke test when I asked if I want to get it done there. I was thinking of a simple process like clear the code, test and pass so what they said really stressed me out. I kept talking about the gas cap, but they kept saying it's normally a MUCH BIGGER problem!!! I placed the new gas cap I already had along with the gasket that evening so I at least, removed one problem that was for sure triggering the engine light to come on. Next day, I visited Mr. Lee at Allen Smog because I remembered one of my ex-coworkers was saying great things about this shop. I explained about my gas cap issues again to Mr. Lee and he immediately placed the reader to clear the code, took time to examine my both old and new gas caps, then told me to drive some miles and come back. It was next day, I went back to Allen Smog after driving 93 miles to report him that the engine light didn't come back. My car passed a smog check 10 minutes later. I was so relieved and happy. I strongly recommend everyone who needs a smog check to visit Allen Smog. Mr. Lee is vey caring, knowledgeable, honest, timely, and professional. You will receive the great quality customer service you deserve! read more

Excellent experience! This business was highly recommended by our car tech. Mr. Lee was knowledgeable, thorough, polite and helpful. There is a convenient waiting area. This is our new Star smog station now. It was helpful to use Google Maps App for driving directions because of the location. read more

My experience at Allen Smog was great. The process was quick and professional. I was able to pull right in without an appointment. In total, the experience took only about 10-15min. Definitely recommend! read more

Update 2022 If you need to have a smog check. Allen Smog is the place to go. I have been coming here for over 10 years. Mr. Lee is very knowledgeable and respectful. I have a 1985 Toyota 4runner that I use when I need to go to Home Depot or get large items. Mr. Lee has the equipment to smog older vehicles. He does RV's and really did help me with my older 4Runner. Allen smog has plenty of parking. There is a clean bathroom and cold water in the waiting area. The service is excellent and the process is fast. I highly recommend Allen Smog when the time comes to smog your vehicles. read more

See all

Great, easy, convenient service. Owner was extremely friendly and there was no wait for the smog test, which took about 15 minutes total. Great value for the money, and would come here again for any smog testing needs. Five stars! read more

Have taken my vehicles there for every required smog check. Fast and efficient service!! Highly recommend.

I highly recommend Allen Smog. I've been bringing both of our cars here for years, and won't even consider going anywhere else. This is a totally relaxed atmosphere and very clean and well organized. This place takes all of the hassle out of getting a smog check - there's usually not much waiting, and the whole process takes maybe 10 - 15 minutes. As it is a one man operation, it's best not to phone ahead - just stop in. read more

Very professional, fast, nice and easy service. Probably took about 10 minutes to do! Allen is a one man shop and is by the best.

Notice that the people who leave 1 star reviews called. He's a one man shop, just go in - don't call.

Mr. Lee was able to fit my old RV in with no notice whatsoever. He was patient and gave honest, straight-forward advice. Waiting area was clean and had a water cooler, which always makes me happy. Thank you for doing a great job for us! read more

Mr. Lee is courteous and gets it done fast. Been going here for over 20 years. His prices are good and you are in and out in no time at all. I like he's open on Saturdays as well. read more

Honestly, getting a smog check can kind of suck. It can take a long time, be stressful in many ways, and is rich with scammers. Allen Smog does not suck at all. It's easy. Mr. Lee is kind and calm and the place is clean and pleasant. He moves fast and you are in and out in no time. Have been going there for the last 5 years or so with a few different vehicles and will continue to. read more

I have gone to Allen Smog for three or four years. The guy who owns is very nice, the service is fast and superb, and it is the cleanest, neatest garage I have ever seen. Today I decided to try and go to a smog place closer to my home in Silverlake, but the two I tried couldn't be bothered to deal with me or even notice that a customer showed up. I ended up driving to Burbank to Allen Smog anyway, and it was worth it. There is even clean place inside to sit and wait, instead of having to stand in the sun, which looked to be my options at the other places. Allen Smog is right off the 5 at the corner of Alameda and San Fernando, so you can hit Trader Joe's or Ralph's or CVS and sneak in another errand after smogging. Or a drink at the Blue Room... read more

For smog certifications, this place is as good as it gets. Cost: Under $60 Free retest I've been here 4 times the past few years, most recently due to my car having a clogged ERG valve. He diagnosed it, I had it serviced by Tony at Tony's Auto Repair in Rosemead, came back it still didn't pass, then went back to Tony who did a revision, then went back to Allen Smog, and passed. Annoying - however I don't have a brand new car. I used to have a place in Burbank, making it convienent, however this time I went out of my way to Allen Smog. read more

I've been coming here for years - and I mean YEARS - when it was on Glenoaks and Allen way back when. Clean, fast, and friendly. I've seen it so many times - we are like old friends. In fact I have to go there today... read more

I just tried calling to get a quote for a smog check and whoever answered was extremely rude and didn't bother to try to find out from someone, how much it would be... bad look for your business if you can't even answer a simple question! all this guy said was, "I'm not the owner here so I don't know. Okay, bye..." read more

The best place for a smog check. Been coming here for years and always great fast service. I rarely ever wait. It couldn't be any better unless I didn't need a smog check at all. Here again for next smog check. Same great service and no waiting. read more

I've gone to Allen Smog for many years, they ARE as another reviewer stated the cleanest shop in town, and the owner is wonderful. Fast, friendly, and professional. conveniently located within walking distance of Trader Joes, Ralphs, Starbucks and The Blue Room. You won't have time to go there while you're waiting for your vehicle though, so fast, it'll make your head swim! Comparably priced, everything is posted, and I've never felt pressured to pay for anything extra. Wonderful experience, and I would recommend Allen Smog to anyone! read more

I have received excellent, professional service numerous times over the years having my vehicles smog checked at Allen Smog. I highly recommend Allen Smog. read more

Only place I'll go to. Fast and easy and he saved a litter of kittens from certain death. Good man.

Real quick breakdown: 1. Mr. Lee is super nice (offered me water and candy) and very professional (gave me advice on keeping car properly maintained). 2. Facility is very clean. 3. In and out in less than 15 minutes. See you next year, Mr. Lee. read more

This place is great! My car is lowered so I had been turned away at other places because they said they would tear my bumper off if I put it on the lift. That wasn't a problem at this place. Got it on got it done in no time. And very friendly service. read more

I found Allen Smog on yelp and am SO happy I did! I have taken both of my vehicles here on different dates! He is quick, efficient, and really nice honest guy. I will always go here for my smog test! He also recommended a great mechanic! read more

The guy who works here is super nice and friendly. He will make you feel at home. If you bring your registration he can scan it in his computer. The computer then sends the results straight to the DMV. I paid for my registration the same day. One can tell he keeps everything neat, clean, and organize. There is places to sit and get some water, as well as a restroom. The only bad thing are his prices he will charge full price. There are no coupons for this place. Honestly, it is worth every last bit. This guy knows what he is doing. He is not playing guessing games like other smog check centers. I highly recommend this place! read more

Always friendly and quick and fairly priced. Great service!

Wow we got our smog check in 15 min. Service was super fast and the shop was really clean - not greasy... Mr. Lee is a one man shop and is really professional and helpful w/ car tips just like others have said. Will be back! I like supporting independent businesses. read more

Excellent place for a smog check. Owner is very friendly and the shop was clean. Quick service in and out in about 10 minutes.

Super nice guy! A lot nicer than the place down the road on San Fernando. I won't name names but I'm sure you can figure out who it is. It took no less than 15 minutes if that. Under $60. Nice, quick and actually appreciates your business. Thanks! read more

Mr Lee is so nice. He was quick and nice. I would definitely go back .

Mr. Lee at Allen Smog is fast, friendly, reasonably priced and a great guy! Getting my car smog checked, he noticed a bulge in my tire that could have been VERY dangerous if it blew on the freeway. I am going directly to my tire place now. Thank you Mr. Lee!!! read more

The owner was so nice and considerate. He performed the smog test quickly and efficiently, then walked me to my car and opened and closed the door to me like a gentleman. I will come back, no doubt. Plus there's a water cooler and candy while you wait. read more

I called and asked how much it would be for a smog check. The guy on the phone replied, "you already called and I told you" and hung up. I had not already called. EXTREMELY rude. Thankfully I didn't have to deal with them in person. read more

Mr. Lee there was ready and waiting for what turned out to be fast and efficient customer service for my truck at $59.75 a pop. This is by far the cleanest mechanic shop ive ever seen. He even has a box of quarters for the change ready for you. Highly recommended read more

Extremely fast. Friendly. Priced right. I would recommend Allen Smog to anyone.

I've been bringing my cars here for years. I highly recommend this place. The owner is nice, honest and very down to earth. Seems to do everything by the book, which is good for the environment and in turn for us. read more
