Just returned from McHenry Smog Center again, and all was as good as before. No frills, just good, fairly priced service. I highly recommend them! read more

Price for smog is not what is listed on their website. I didn't have time to go elsewhere. Otherwise, the smog check was quick and efficient. read more

Great location. Was in town from Bay Area and needed a smog. They were Fast and good price. Only 5 minute wait

The most painless smog check! They get you in and out and are super friendly and affordable. 10/10 recommend!

Been going to the smog place my whole life since I could drive. Quick, Knowledgeable and efficient. Fair prices as well.

Arrived at McHenry Smog Center as a walk in for a smog test on and within 15 minutes it was done including necessary paperwork and reporting! I'm impressed - wow! read more

Made an appointment & showed up a bit early but the owner/mechanic took me in right away. I went inside the little shop waiting area while he completed my SMOG check. The waiting area reminded me of when my dad had a shop, it had cute little touches of "family-owned" --- tons of pictures of pugs, lol. I am a fan of pugs :) It seems to be family run since there was a young man who helped me with my forms and cashed me out. He was quiet but polite - straight business. All in all, I was there for maybe 10 mins. tops. The only downside is that when I entered the address into my GPS, it brought me to the next street down for some reason. So just something to point out when following your GPS, turn sooner than you think you need to. read more

Efficient. Used them many years and they are consistent.

Super fast. I was in and out in 5-10 minutes. A friend recommended me this place and I will come back every time I need a car smogged. The pugs on the wall are cool too. read more

I've been going to McHenry Smog for years it's a great place and I highly recommend it

I was able to be in and out in under 20 mins. Team was friendly. Cheaper than any other place I had called. I'll be going back as needed for my smog checks from here on out. read more

Walked into this business because it was close to where I live. I was just going to make an appointment. Since I had my DMV renewal with me, they said could do it right now and would take about 10 minutes. Fabulous....let's do that. In 10 minutes they were done, paid and got my paperwork and off I went. Really nice people that work there. Absolutely would recommend McHenry Smog to anyone and will be certain to go back in the future. read more

Mchenry Smog Center is THE place to go to get your car/truck/SUV or whatever to get a smog check!! Khanh and his team run a very efficient shop! They are always friendly, and get you in and on your way as quickly as possible. There is a quaint, cute, and clean waiting room with some chairs inside. If you are a dog lover (especially pugs) or an animal person, you will adore the waiting room. (Their website says it is a pet friendly business). However, you won't spend too much time in the waiting room as I said they don't have you wait very long if you have an appointment. I would strongly encourage an appointment, but it is not always required. Depending on their schedule and if they have availability they ususally take walk-ins. It is easy to find on McHenry (tucked in the middle of two other shops in the same parking lot). It is right next door to a Mister Car Wash (formerly known as Prime Shine), and across from the Barnes and Noble bookstore/Promenade Shopping Center. If you need your smog check, I would highly recommend McHenry Smog!! read more

They are the best in every way. They are super fast and efficient. I cannot recommend them enough.

We have been using this place for a few years. We do have several vehicles and I've bringing each one of them for smog certificates when needed. No games, no mimics, just a friendly and professional service and good value. Superb and professional staff and service. I wish I could give them 1000 STARS. Thank you. read more

See all

Friendly people and a speedy smog check. My new go-to place to have my vehicles smogged. Good price too.

Outside of my normal foodie review but ahh I had to give a good review for this place. Their interior is decked out in PUGS. How freaking cute! I've never seen so many pug paintings, antiques and anything pug related. Like who doesn't love pugs lol The pricing was good. It came out to $45 for my 2018 Civic. Also, they're pretty fast. I came late in the evening after getting an oil change (after work really) and I was in and out in a span of less than 20 minutes with multiple cars in front of me. read more

Asian-ish looking tech pulled my car in. Proceeded to open the hood, looked around and then backed my car out and told me to go someplace else. He indicated that I had "too many" aftermarket parts. I tried to explain the car (1996 Saleen S-351) but he would have nothing to do with me and walked away and hid in the back. The shop seems to have no knowledge of "specialty" cars. This shop can not be recommended for any "specialty" cars. read more

So easy, so fast. I've been going there for years. Great price. Professional. I highly recommend

Everything went smoothly. I arrived on a Sunday around 11:00 a.m., and the test was completed in less than 10 minutes. They were fast, efficient, and professional. Highly recommend! read more

Fast. Efficient. Affordable. I was in and out super fast as a walk in. Great place to get a smog done.

I walked in, and was out within 10 minutes, they charged me $50. I was able to go to the kiosk inside Save Mart the next morning, to renew my registration and that took less than 5 minutes. I was very pleased. read more

Great fast service! It's my new go to close to home smog location. I've been there 2 times this year.

The service was great! My appointment was right on time and they had my car finished in about 20 minutes! $45 bucks flat for the whole smog! Thank you for such great service. The lady at the front desk was very sweet and kind as well. read more

Took my 2016 Ram for a required smog for dmv vehicle transfer. They take Apple Pay , and were in and out in about 18 minutes. So easy , 45 bucks even , super nice staff. If you're a woman who needs smog, this is a safe place where you won't get pressured . Would send my little sister here when she's due for smog. Will be back soon. read more

Great place, they got me in and out in 20 mins. Super friendly. Definitely recommend. Will be back Thanks guys read more

I always take my cars here to get smogged. Why? Because they always fit me in, get it done in a matter of 15 minutes or so... and they are kind. Great place and I will continue to do business with them! Also their prices are great. read more

It was so easy to make an appointment online. I was quickly confirmed and I had an almost immediate appointment and estimate. Not only that, when I arrived everyone was kind, helpful, and efficient. Everything was explained and easy, even on a rainy day. The business is just a little back off of McHenry Avenue but there's plenty of parking and the sign for "Office" was clearly marked. They electronically transmit the information to the DMV so I could go home and register my vehicle online right away. Their reasonable fees are clearly marked so you know exactly how much it will be ahead of time. read more

Super quick and easy!! Literally took less than 10 minutes ! Will definitely recommend

I am new to the area and called around several smog shops because I had a few family cars that needed to be smogged. This one by far had the best value! Too many smog shops are charging way too much these days for smog that take less than 10mins. McHenry charges $45 per car. read more

McHenry Smog Center - Smog Check Stations Near Me - Modesto, California

Best price I could find locally and had a large amount of available times. Not a big waiting area but I was in and out.

My car did not pass smog to start and the young man told me to drive 100 miles and come back. Which I did do, only for me to comeback and he decided to close the shop 2 hours early. To add insult to injury, he told me to come back tomorrow morning and forgot he told me to come back on a Sunday. I do understand as a local business that you might need to close early when it's slow. But when you tell your customer to come back the same day and decide to close early is very poor customer service. That was the first time I went to McHenry Smog and it will definitely be my last! PS, I took my car up the street and it passed! So take your car to either Valley Smog & Tags or Stanislaus Smog instead if you want good customer service! read more

We have been coming here for years. Friendly Fast Service always! They are pet friendly so bring your fur babies along for the ride!!

Very easy to go here and get a smog quickly and at a fair price. The waiting area is comfortable.

Went here to smog my 2007 Toyota Corolla. Had no problems getting in and out, fair pricing and everything was smooth. I had to go here because Stanislaus smog was closed on Sunday, where I normally get my smog. I would recommend both Stanislaus Smog and this place, I'll update this review if I ever have a close call or failed smog. Like many places in Modesto, not the easiest place to walk but across the street there is TeaDaze and a Barnes and Noble. Our smog took about 30-minutes, you can also walk to the movie theater if you're feeling adventurous. read more

I love the staff. Selling a car and it didn't pass since I had recently changed the battery. They were so accommodating on a weekend to give me instructions to get the car error codes cleared, and rechecking multiple times after I put some miles on the car. Would never take my car anywhere else for smog services. read more

5 stars 10/10 would recommend! Came in for a smog check, I passed. I was in & out in 10 mins quick and fast. $45 to get my vehicle smogged.

Always very friendly, fast, & most importantly professional. I've been going here for a few years now & have absolutely no reason to take my family's vehicles anywhere else! read more

Friendly and swift smog service. I was in and out in less than 30 minutes. I definitely recommend them to family, friends, and yelpers.
