Fast and inexpensive! Great service! I was in and out in less than 15 minutes - I'm a repeat customer won't go anywhere else. read more

I came here for a smog and honestly had one of the best experiences I've ever had in the years I've had to get one. Daniel was running the whole show by himself (juggling four cars at once) and I still got out in 20 minutes! That man deserves a raise! He was super friendly, efficient, and had me laughing with his Wienerschnitzel hat that said "I wieners." It was $40 out the door, and I came on my husband's recommendation (he's picky about car stuff). Now I'll be recommending them too. Fast, friendly, and fair pricing. read more

Quick and easy, very reasonably priced. I have got my car smogged twice there and will continue to return.

Friendly service and no price gouging. We called ahead and we're provided information that was accurate upon arrival.

I needed to have my 2017 Nissan smogged. So I came to Yelp and found Ontario Smog. I saw there were many good reviews & so I came in today. It's located on Mountain/Holt north east next to Liberty Bell eatery. When we came today it was very busy, but don't let that turn you away. There was about 3-4 employees and they were quick. The service was fast and employees were nice. Checkout the coupon on their website. It was the best value than any other smog shop. I told my sister, she's coming here when her smog comes up later this year. I definitely recommend. read more

Excellent service!! I was in and out in 20 mins!! Definitely great for a busy person.

It was a pleasure doing business with Ontario smog. Great service, fast,and courtesy! read more

Customer service is great. Only waited 20Mins total which included my smog check and that took 10Mins. If you pay cash, you get a discount. $26.75 + $8.75 for the certificate. $35 in total. The parking lot is super small and there are bollards everywhere that divides the property. Make sure you get there at a decent hour before it becomes a pile-up. read more

Danny was great - very efficient. This was the fastest I've ever experienced. Great price!

Came here for the first time a few days ago and I will definitely be returning. Great and friendly staff. The whole visit took about 15mins.

Great Customer Service loved it, quick service, nice people, and easy peasy! Thank you for making my day easier and my SMOG COMPLETE!

Super quick and accommodating . This is my 3rd visit and I never waited longer than 10 minutes for a smog.

Very fast, good capable and very pleasant gentleman. Highly recommend! Will come next year and the price was better than most.

Excellent service strongly recommended Ontario smog to anyone who needs a smog check.

So grateful for Yelp! This place is the best place I have ever been to get my car smogged. When I pulled up, Danny & Anthony greeted me with smiles & took my car right in. They were respectful, professional & quick. I told them I found them on Yelp & that I was paying cash. They gave me a discount! I highly recommend this place to anyone, especially women (you know how most mechanics treat us), who needs to get a smog cert. This is a small business that I am proud to support & will recommend to all my family & friends. Thanks again, guys!! read more

I just took my 2012 Hyundai Genesis Coupe 2.0T here to get a smog check. Honestly I wish I can give them 10 stars. I totally recommend coming here if you need a STAR certified smog check. Upon arriving I was greeted by a guy (I think his name was Danny). He was very friendly, honest, and super chill. My only regret is I WISH I found this place sooner, it would've saved me some stress and a couple of headaches! It took about 15 minutes to get me out the door. There were a few cars ahead of me so I recommend getting there a bit early, for me personally it was no problem at all and I didn't mind waiting. They have a sitting area with a bench and two chairs that you can sit on while you wait. I live about 25 minutes away from their shop, but I don't mind making the drive. After today's experience this is OFFICIALLY my go to smog place. I'll also recommend my friends and family to go here too. The other guy that helped me out was super cool, funny, and knows what he's talking about. (I'm sorry I forgot to ask for his name, but he did have a couple of tattoos on his arms.) Thank you again! You guys are awesome! :D read more

Five star service to these men (Manny, Rob and Mike) at this Smog check station. I called ahead and was able to get an awesome deal on Smog test and when I got there the wait was less than 5 mins. The station was easy to find and I was pleasantly greeted upon arrival. I handed over my registration and ID, paid my fee and was able to enjoy the rest of the day. Thank you so much for making this experience stress-free. I highly recommend this location for your next smog test. I saw that they were on Yelp's top favorites for 3 consecutively years and now I see the reasons why. read more
