Perfect smog check business!!! They're always so busy, I was excited to find a quieter time (early morning!) and the owner not only got me in right away but the check only took ten minutes. He was so professional, funny, easy to work with that this was as un-stressful as possible! 100% recommend this business! Literally the easiest smog check I've had done in San Diego! read more

This guy is the bomb. He has helped me "Pass" smog tests for years. He has nothing to sell you but his service, and he does that well. I never fall for those "Low" advertised prices with other smog test shops who really don't want you to Pass, so they can "Fix" your car for you! Check him out, his name is Hiep and he is a real pro. read more

I love the early hours. Made it super convenient. Smog check only takes about 10 minutes. Lots of waiting room. Waiting area is nothing fancy but don't really need that when your just there for 10 minutes. Hiep gave me a good price and had great customer service. read more

Fast friendly service. The waiting area is in the garage with fresh air from big bay doors. Took about 20 minutes in and out.

fast and great service every time we go its fast and great price john was super attentive and polite i will be back totally recommend this place read more

My family have been customers of Excel Smog for over 10yrs now and the service is always good and his prices can't be beat! Mr. Nguyen is always polite and professional. He gets the job done fast and he knows cars and smog checks. We are very thankful for Excel Smog and are life time customers here. Thank you Mr. Nguyen aka Excel Smog!!!!!! Ms. Triggs read more

When you need your vehicle smogged, Excel is the place to go. I have been coming here for the last 15 years and have had nothing but 5-Star service. The owner, Hiep Nguyen, is a perfect example why immigrants help to make America great. He is a proud American who came to the US As a refugee after the Vietnam war and quickly started contributing to our country. First a mechanic he later started Excel Smog. Along the way he became a US citizen, mastered english as a second language and raised his Family. When you go have your vehicle smogged ask Hiep about the gigantic American flag on his back wall. He is as honest as the day is long, funny, efficient and fast. You won't regret your choice of Excel as your first Test Only smog center read more

Excellent service. Hiep is a professional with integrity. He also has a great sense of humor. Highly recommend Excel Smog!

I have a taken my vehicles to this location for the past 15 years. The owner is honest kind and helpful. I would recommend him to anyone looking for a reasonable priced place to have your vehicles to get a smog check. He's quick and he's f you have to wait the waiting area is very comfortable and clean read more

Once again, he was fast, friendly and even remembered me from years past! Always a pleasure to take my car here. read more

Recommended 100%. The owner is super friendly, upfront about the price and an honest worker. Don't be intimidated if his garage is full, he'll get you in and out quickly and his reports get sent to the dmv asap. I went in for a smog check and within an hour it had already updated on my dmv account. I bring in all my family's cars with him and always recommend him. read more

Thank you, Hiep, for extremely prompt and curtiuous service. Nice clean shop and fondly customer service. I'll keep coming back!!

Best prices, quick service, super friendly and honest. Came here after talking to a number of other smog check vendors who tried charging me extra money and the service was super unfriendly. Absolutely recommend and I wouldn't think of going anywhere else! read more

They are very good for smog checks. If you havent been to this place before several things to know is to either park to the right if cars are already their or pull in all the way dont block the out going drive way. Also the restroom has a lock but is not locked for customers ask for the key and you will get it. Very fast service a has a great area to relax well waiting and cable and wifi access. read more

For some reason I had to smog my car 2 years in a row so I ended up here due to proximity to my place. When I arrived the guy working there was finishing up the car before me. I could barely make out what he was actually saying but he was very nice and in a good mood for no apparent reason which was cool. The waiting area, which is inside the actual shop, has the back seat out of a van and additional chairs for watching tv, which was on Travel Channel! It was pretty cool to be able to actually see whats going on with my car and whats being done. The actual smog test on my car took about 20 or 25 minutes but it went by quick because I was watching one of my favorite shows, Bizarre Foods. Thank goodness I passed, $50 out the door. I'll definitely come back when the DMV makes me. read more

Great busines, excelent service. Friendly staff will contine to come back. Owner has a great sense of humor and is very profesional.

Really good smog place, I'll recommend anyone to go to them and check it out. It takes a bit of time because they have so many going to them but its worth the wait and they explain everything well. read more

See all

Great little smog shop. Was in and out in about 20 minutes. His prices are very reasonable. His shop is very clean. I will certainly go back in the future read more

Having to get a smog test is almost like going to dentist - you dread having to get is done. But having a great place to have your smog test performed is like having a great dentist (which I do). I've been having my many vehicles smog tests performed with Excel Smog for about the last 12 years. Always a pleasure to do business with - Hiep is very personable, honest and on point. HIghly recommend Excel Smog when your vehicle gets the dreaded "smog test due" from the DMV. read more

I've been going to Excel Smog for about 3 years now with the 2 vehicles I own and Hiep Nguyen is absolutely fantastic! I own a 95 Jeep Wrangler so the testing is a bit more extensive so instead of the 10 minutes it takes for a newer car, its about 25 minutes for an older manual transmission. Most smog centers will either charge more money or say they don't have time and this has NEVER happened with Hiep. I highly recommend taking your vehicle here, you won't be disappointed. read more

My go to Smog station. Fast and friendly service. Reasonably priced as well. Usually I get in and out in under 30 minutes. read more

Hiep is amazing! I went in, he smogged my car and in 10 minutes I was out the door. He is an honest business owner and doesn't try to take peoples money ! Go here ! read more

Great place to get your smog test. Honest, efficient, good value. Love the owner. He's a 5 STAR guy running a 5 STAR BUSINESS.

Very honest and kind man who has ran this place for 16 years! The reviews don't lie, take your car here for your smog tests!

Great experience! Super friendly and I was in and out in 15 mins. I definitely will be back.

I have been using Excel Smog for 10 years for both of my family's cars. Hiep is the owner/operator and he's here every day, so the experience of visiting his shop is consistently high quality. The shop is simple, but he does have a space for the customers to sit and watch TV while he quickly takes care of business. Highly recommended, Hiep is a pleasure to work with. read more

Hiep is the best! He comes from a mechanic background and can help with whatever situation you have - whether it's faulty oxygen sensors, secondary air injection, evaporative emission control system, etc. Also the pricing - he has EXTREMELY fair pricing and actually showed me receipts from his customers that took their cars to other places. Upwards of $80 or $90 is insane for a 10 min smog test. Hiep charges $50 and is incredibly nice and helpful. If you live in San Diego, stop wasting time and go here. read more

Excel Smog is great! The service was fast & the gentleman was very friendly. A great place to get your vehicle smog check completed.

Amazing fast efficient service! Always come here for any smog needs! Thanks for getting me in and out so quickly!!

Amazing customer service!!!!!! Great prices too! We came early and the morning store owner was extremely nice and full of happy energy! He got us in and out quickly. I definitely recommend coming here and I will be coming here again! read more

Great smog place. Took 15 min to do the test. Mr Nguyen has great customer service. Cant beat the price. I recommend this place and will be referring my friends here. read more

I went in yesterday to get my smog checked and was finished in 10 minutes. Today I got a call from Hiep, the owner of Excel Smog, and he told me that I overpaid and that I should come by to pick up the money. I was very pleased by his honesty and I will be sure to come back! read more

I've been coming here since I moved to the neighborhood. Hiep Nguyen is always friendly and he always remembers me. The smog inspection goes quickly and the price is reasonable. I recommend Excel Smog to my friends and neighbors and now I recommend it to you! read more

Comfortable and friendly. The price I paid was much less than I've been charged b4. And I got a reference to North Park Imports(next door) for repair work on my car. Highly recommended!!! thank you Mr. Nguyen! read more

I am extremely satisfied with the service I have received over the past 5 or more years of having my vehicles smoged here. I was in and out in less than an hour. Thank you for the service you provide. a job well done. read more

Made an appointment for 8:45 and was greeted promptly and was out in 20 minutes. It's a garage but they have couches and a TV while you wait. A real friendly guy runs it, read more

this place is amazing. i showed up at 5:55pm, thats 5 min before they close, i was ready to beg for a smog check. i had my catalytic converter replaced that morning and needed to pass smog that night. I got out and didnt even have to ask, she said right away they could squeeze us in. They then knocked $11 off the cost! So everything ended up costing $45.00 The test was over before we knew it and we where out the door. They even took care of sending off the smog info to the DMV for us! the next time i need a smog check, im going here! read more

I hate being the first non-5 star review for a place. I liked the technician, the check was fast and the walk-in, no appointment shop was convenient. But I failed my test due to some 'lack of communication between my warning light system and my dash'...or something like that which was hastily explained to me. I was referred to the San Diego referee service at Cuyamaca college and made an appointment to go there. After an hour there, the ref told me my car passed with flying colors. He said my cars indicators were chatting up a storm and he had no idea why Excel had failed my auto. I don't think there's anything shady about Excel Smog, but I probably won't go back. read more

It is my only place to bring my cars or my Friends cars no cheating are very honest and it takes about 30 to 40 minutes if is not very busy I recommended 100% it is one of the best I been coming to this place since 2001and I'll visit this place very soon Thanks for all you're hard work and for been very honest I'll be there soon !!! read more

This place rules. Always quick and the gentleman running it is rad. Only place I take my shitty old truck to smog it. Passes everytime. Cannot recommend enough. read more
