McHenry Smog Center

Took my car for smog test. Receptionist was very nice and professional. I was in and out in less than 20 minutes. I will recommend this business to my friends and go there again next time I need a smog test done.

Brought my other vehicle in to be smogged. Was quoted 20−30mins and I was out the door in just under 30. Another positive experience, will continue to do business here.

Wonderful service. I took my 86 El Camino here and she passed with flying colors. The receptionist was wonderful and the man who ran the test on my vehicle was personable and very nice. They have a great price and I am more than satisfied with my service. I’ll definitely be coming back to them for my other vehicles and recommending then to friends and family. Thank you again!

Great smog place! Came in without apptm. And he got me in right away. The price is great too! Very good customer service. Khanh was awesome. Totally recommend this place.

This star certified smog center is the best! Called for an appointment and was able to get both of our vehicles in half an hour later. The administrative professional IS professional, knowledgeable and kind. A gentleman came in and had a rather long-​winded story, but she patiently listened to him and empathized with his problem. I also appreciate that when quoted a price, I was told $ 40. Not like a previous experience I had elsewhere, which had a $ 29.95 «coupon,» but by the time they added the fee for the smog certificate and taxes, etc., it ended up being $ 39.95 anyway. The other place also tried to upsell me into getting other services done. Nice Hawaiian music and big comfy chairs in the warm waiting area.

My husband just bought a new commuter car. He asked that I take it to Khanh at McHenry Smog. I called in and told Khanh I’d be there within 15 min. He got me right in and had me back on the road within 10 min. Thanks Khanh for the great customer service and speedy service. This is the best place to go in Modesto for your smog check needs.

Great first experience! Will definitely be returning. Was quoted 20 – 30 minutes for my truck’s smog check over the phone. When I got there I was told 15 minutes. He immediately took my truck back and I had to have been there 10 minutes and they were done! All with no appointment.

Fast and friendly. Great deal $ 40 out the door in about 20 minutes. If you need smog, go here!

AWESOME service and great staff. Seriously. In and out in about fifteen minutes. WILL definitely be going back, as well as referring anyone I know. Thank you guys for the great and friendly service, very much appreciated.

If I could write a one-​word
review that encapsulated my experience at McHenry Smog Center. One word that would describe the customer service, and the time it took to get my car smogged. ONE WORD to describe how my visit to this establishment went…
it would be…
Awesome!
Some of the friendliest, sweetest people I have met in the service industry. I felt like I had known Khanh and the lovely lady behind the counter (sadly I didn’t catch her name) for some time. This was my first visit, and will not be my last! I will recommend them to ANYONE I know. Phenomenal, and FAST service. Thank you so much!

Took my 1990 mercedes here for a smog. I was told it failed because the timing was off. So I took it to the mercedes dealer and had the timing checked. They just LOL and told me. It has electronic timing and is not adjustable. Unless you have a computer and is listed that way in all smog books and computers state wide. They went on to show me that it was dead on timing. In other words. The timing was perfect!
So I took it to anther smog shop and it passed with out making any changes at all. I have no idea why this guy failed my car. He seems to be a nice guy and the person in the office was nice. But! They did make me pay the test fee. I think if they fail your car and you take it to the dealer and they do nothing to it and it passes with them. I should be entitled to a refund. When I called and told them about it. They did not to discuss it. So please be warned. If your car fails here and you take it to the dealer and it passes. Call the Bureau of automotive and file a claim. This will keep them honest. I may look like a dumb field worker. But I do my homework..

Excellent service. Lovely experience overall. Clean, quick and professional. Highly recommended!

I have to say that this family owned business is one I will gladly give my patronage too. They gave me amazing service and treated me like a friend. Not only that but the prices are great and they had me in and out in no more than 15 minutes without an appointment! I did get there right before they got super busy which was perfect, but you couldn’t ask for more.

Need your car smogged, look no further.
I called to make an appointment and was able to get one right away. From the phone call through the complete check everyone was so helpful and friendly. They were so quick, and even backed my car into the space for me to exit so easy.
Getting the smog for the car registration is usually such a hassle, but today at McHenry Smog it was a pleasure.

Don’t review much but I have to share this place. Khanh is the man! Very knowledgeable and super helpful. In and out times are unbeatable and the front desk employee (s) are super friendly as well.

Okay, Unilocalers, you had me come to Motown half an hour earlier than I would have for a planned lunch at Golden Corral with family just to get my car smogged across the street. Thank you.
Not a lot I can say beyond what has been said. It’s a small, clean shop with good rates and great service. Nothing condescending or gruff about these men. On a side note, they love pugs and have several «American Graffiti» pics hanging on the garage wall.
If the DMV says your car needs a smog check, and you live within a short drive of Modesto, then this is the place to come.

I called this morning to get an idea of cost for a smog and certificate for a vehicle transfer. They were very friendly and helpful, quoted me $ 40 out the door. I did not set an appointment as I had several other appointments to go to prior to this, plus I had my newborn with me and was not sure if he would still be doing okay after running around all morning. Around 1PM I stopped in with my little guy who was napping and was promptly greeted and was told it would only be ten minutes. If it was ten minutes that was the fastest ten minutes of my life! The price was as quoted over the phone and I was back on the road in no time.
I will definitely be back for future smog jobs.

Been here many times with many vehicles, including my RV. They can be pretty busy, but if you call ahead, they’ll make you an appointment, and they are good about getting their appointments in on time or early.
Their prices are very fair — they didn’t overcharge like some places do for the RV, which I appreciated. Friendly staff, good service, good price.

Great service and value. Had an appointment at 11am, showed up at 10:45am, and was all done by 11am. Can’t ask for anything better. I’ll continue to use them.

This place is one of the best deals in town to get your smog done. They’re affordable, always quick & are able to take me in on the same day.
