I've used this business several times and have never been disappointed. It's located behind the Arco, at the west end of the work bays. They work quick, and the prices are reasonable. There is a place to sit and wait while they work on your car, but by the time you get comfortable, your car will probably be done. They wore masks and asked people to social distance while waiting. Again, they work so fast that there aren't too many people waiting outside. They do ask you to wait in your car if they are currently smogging another car. I will continue to use this business-they are reasonable and quick. After getting a smog check you can go to the Rosemead DMV to renew your registration via kiosk (never a wait) -if they submitted your info the sticker and registration card will print right there. If not, they will mail it to your address.

The mechanics, Chris and Armin did a quick Smog test and helped change a tire! Great work thank you!

Chris and Armin were very sweet and helped run a smog test. They helped me out during a very stressful situation. They helped change a tire after I hit a curb on the way in. They were so kind. Thank you for everything!!!

There's a couch and a massage chair, in case you get stressed out waiting for the smog. =P

Friendly service and fast! And all at a reasonable price! It's a small location connected to the same building as RPM Auto. Tony was nice and cheerful and when I had a question about maintaining my car he didn't talk down to me (the way other car guys might when talking to an unassuming girl like me) but took the time to explain to me how to upkeep the car for the future. Plus they've got icicle lights hanging above the office door and a decorative fountain. So, you know, the place has flair. read more

Thought I would come in at a convenient time a little after lunch time, but it wasn't for the owner. Since everybody comes during lunch time, I brought my car in right after the rush and stopped the owner from eating lunch, but the owner didn't push me away because he was hungry and couldn't take lunch. Customer service is absolutely great. Very friendly and felt comfortable like I'm at a relatives auto shop. The smog test was literally 10mins and I was out within 15mins. They don't take Amex, but take visa and mastercard. I would recommend this place to my co-workers and friends in the area! read more

Came here to have my car do a smog check/test. When I arrived to the area I see a car was ahead of me, but the owner was quickly get my car to test and I'm glad i still have my k&N intake sticker with me because it is illegal without the sticker for any aftermarket part installed in the car. Thanks Yelp! I can use the check in for only $40. The test was quick like 15 minutes or less. When my car is done, I was inform by the owner about paying for the car registration sticker the next day or any other day after the smog test because the data haven't transfer to the DMV yet. Really nice and friendly place. Would recommend anyone to come here for their smog check required. read more

Great family-owned business. Tony, his wife and son are frequently together in the garage, which lends to the honesty of their business. It is located behind a gas station, in the industrial side of town bordering south Arcadia/Monrovia. LTO is efficient and professional, taking your DMV form and returning it afterwards with an informative pass/fail sheet of details and a detailed receipt. There is a comfy couch for you to watch, as well as complimentary hot beverages and occasionally, donuts. My family and I have taken our cars here for a few years and Tony and his technicians are always warm and friendly. It's like seeing an old friend. Also helps that Tony appreciates my old hunk of metal for what it is! You can call ahead of time to see how busy it is. read more

This past Saturday I took my daughter's VW to this station. It was her request to take it there. It was getting late on Saturday and my daughter needed to get it done before she went into a late penalty for her registration. I had a very brief wait while one vehicle was being finished. The shop I have previously used for our cars has one plastic chair for people waiting. I was happy to be able to sit comfortably here, particularly since I had been working hard all day. Tony was the tech who helped me. Very friendly and outgoing gentleman. He was efficient in going about all the required checks. In a short time the testing was over, I got the certification for my daughter and was ready to be on my way. I will be back there this week with first of two cars we have to have tested this year. read more

I was recommended this shop about 6 years ago, and this is the only place I take my cars to get smoged even though it's about 10 miles from where I live. I had just purchased a new Jeep and it had issues. Before they even smoged it they could visually tell me what needed to be fixed. I wrenched on it and it passed with flying colors. If you have a car that is questionable this is a great place to go for a pre test. They also shared with me some tune up tricks to keep my engines running proper and clean. Really good guys. read more

Our priority is simple — delivering fast, reliable smog checks customers can trust. What makes our business unique is our commitment to convenience and professionalism. We understand that our customers’ time is valuable, which is why we strive to provide quick turnaround times without sacrificing quality or compliance. Our technicians stay up to date with California emissions regulations and testing procedures to ensure every inspection is performed correctly the first time. We proudly serve individual drivers, commercial fleets, diesel vehicles over 14,000 GVWR, and Clean Truck Check HD/IM inspections.

History

Established in 2008.

Longden Test Only is a proud immigrant-owned business built on hard work, sacrifice, and determination. Our family immigrated from Armenia to the United States in 1992 with big dreams and the hope of creating a better future. Starting over in a new country was not easy, but through dedication and perseverance, we worked our way into the automotive inspection industry and gained years of hands-on experience in smog testing and emissions compliance. Over time, we developed a strong understanding of California’s evolving smog regulations and built lasting relationships within our community by providing honest and reliable service. Longden Test Only was created with the goal of offering accurate, unbiased smog inspections customers can trust. Today, our business reflects our journey — built from the ground up through integrity, experience, and a commitment to serving our community with professionalism and care.

However, when I expressed concerns about the oil condition and asked if they could redo the service for customer peace of mind, I was told I would have to pay again. The original manager on duty during the service was Mike. What concerns me most is not just the oil itself, but the lack of transparency and unwillingness to address a customer's concern in a professional way. When basic steps like resetting the maintenance system are missed and the oil appears questionable, it's reasonable for a customer to ask for reassurance. Unfortunately, I did not leave feeling confident that the service was handled properly. Luis refused to redo the service free of charge and at this point I realized that it wasn't doing anything by going back and forth. I would recommend customers going somewhere else.

So happy with the service. I would have to say my experience here was better than 99% of my dealings with any services, including restaurants and hotels. Tony should consider a career in the hospitality industry, his customer service skills are exceptional!! My van failed the first test, but I was still content to return knowing that I would be greeted in a friendly, professional manner. And the prices are very reasonable with no coupon scams. I found him on my GPS as I was in Irwindale area. I hadn't even seen him on Yelp. But now that I see his rating, it's no surprise the business has a solid 5 star rating. Enough said, I'll be returning. To bad smog tests only come ever 2 years. Philip read more

Really good job - the 5 starts these guys are receiving are well deserved (I was first suspicious of so many good reviews, but now I know why). No thrills, no latte, no plush pillows in the waiting area - just a simple and honest smog check station, with friendly and super-fast service. No reservation required, but be mindful that there may be a queue during lunch time. Tony inspected my car, and he was thorough and discussed with me the typical (and some atypical) reasons why so many vehicles fail smog inspections. More than a "car guy", he's a "people person". Note: AMEX credit cards are not accepted. read more
