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. read more

I was referred here by Stuart at Jiffy lube on McHenry. Kahn, the owner, was great. He was friendly as got right on the job. I was in and out quickly and appreciate the fact that he seems to be a hard working local business owner. I'll go back anytime I need another smog. Kahn earned my repeat business. read more

Super nice couple running this shop. I told them I had come because of their yelp reviews. The wife asked if I could show her. She was blown away and a little emotional about how well her and her husband's business was doing. I love how it's not a greasy manly shop. It has cute pugs, Aubrey Hepburn photos, purses, super cute bracelets to look at. The purses and bracelets are available for purchase. You are in and out so quick which adds a star! read more

This place was really helpful. The woman at the desk was really nice. I didn't have an appointment and asked if I could come back later but I had to be at work before that and so I asked her if she could recommend me to somewhere and she talked with her husband and they said it was fine they could squeeze me in now. It took like 15-20 minutes. I was in and out and they were both super nice and friendly and the price was great $40 out the door. I would recommend this place to everyone. read more

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. read more

Very friendly! Khanh had my BMW in and out within 20 minutes! Price was very affordable and the service was top of the line!! I'd definitely recommend him to anyone needing a smog done! He took care of the DMV paperwork and was very friendly off the bat! Thanks for everything Khanh!! read more

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. read more

Kahn is always smiling and is very quick to get you on your way. Only prison I use for smogs!

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. read more

Great service!great price!khanh the owner is a very nice guy to go to. Ive been coming here for the past eight years.

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. read more

Best customer service! McHenry Smog was recommended to me by Car Pretty when their smog machine was down and I had (of course) waited until the last day to do my smog. Made an appointment and was AMAZED at how friendly, fast, and all-around awesome this place is. My husband then took his car in today, walk-in, and was in and out in less than 20 minutes! Keep up the great work McHenry Smog Center - you've earned two new loyal customers! read more

Great fast, friendly service! Highly recommend! I will bring my other cars here when smog check is needed.

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. read more

Chose this store front because it was close to me. And I'm extremely satisfied with their services. Quick, friendly and great customer service. Before I even got out of my car an employee was helping me park. The front desk lady was friendly and helpful. Price wasn't bad at all and would definitely come back or recommend it to anyone. My only suggestion is come early because they seem to have a steady flow ow business. Which is great. read more

Quick and easy and cheap. Took my BENZ in for a smog check. I thought I was going to wait for more than an hour, probably waited for 20 minutes only because there was somebody ahead of me. The pretty gal that was at the front desk was very nice and gave me great service. read more

Great place to get a smog done. I stumbled upon this place while waiting for my husband to grab a few things from O'Reilys. I live in Salida and attempted to get a smog closer, but the shop was swamped and wanted to charge about $60 total. I didn't make an appointment at McHenry Smog, but the owner had a break in between and totally took my car in. The waiting area is clean, cool and full of great stuff to look at. I left with a smog cert, a few bracelets and a few extra bucks in my pocket! read more

I called to see if I had to make an appointment (it was a Sunday) and a very courteous woman on the phone said they could get me in right away. I drove down and the same woman on the phone was at front desk and wrote me up, told me I get a $5 discount for coming in on a Sunday and was out within 10 mins. Great customer service and speedy service all together! read more

The clerk the mechanic were nice and friendly. Service was easy and FASSST!!! Got my smog done in less than 20 minutes and didn't have to make an appointment. read more

In and out in less then 30 minutes with a pass. What more needs to be said. Staff is friendly and price is comparable to other shops.

Very personable, quick service, very fair prices. They were almost half the price of another of place that screwed up our smog (wrong vin) so we ended up here. The lady in the office was so sweet and kind. We have one more vehicle to do and we will definitely come here. Not only was the service spectacular, but we got $5.00 off because we came in on a Sunday!! Who does that?!? This place is awesome. It was definitely worth the hour and 15 minute drive for us! read more

This is a good place to get your smog. I suggest getting and appointment as they can be busy. They will squeeze you in if you are a walk-in. There is no upsell or trying to scam you at this business. I notice they don't try to scam the women customers either so they have at least half women customers every time I go there. I have been using them for years and highly recommend them. Notice all the 5 star reviews? read more

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! read more

I went on a Friday at 2:30 and was in and out in about 10 minutes and it costed $40. I would definitely go back!

Great service. I went in as a walk in and they made it quick and easy. Also the smog check was inexpensive. Good pricing and great service.

We own a local construction company and bring all of our vehicles to McHenry Smog Center. Their customer service is excellent and their prices are affordable. I really appreciate them making the whole process simple. read more

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. read more

Great service, good pricing and cool people. With an appointment at 10AM, start to finish was about twenty minutes. The waiting area was comfortable and the owners clearly love pugs. I'll definitely be coming back. read more

Great service super nice guy the place to go for smog

Great customer service! Very sweet lady who runs the front desk, called for a appt , the last one at 4:40 pm & they got us in and out within 20 mins. Would come here again, for the smog & certificate it was $40 even! Not bad at all. read more

Great customer service! Easy to get an appointment. I LOVE that they're open Sundays so that us procrastinators can finally get it done. Lol Sunday pricing is a great bonus! Will continue to come back to this establishment for all of our vehicles. read more

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. read more

Great place for a quick smog. It was quick and easy and the guys are great to talk with. Highly recommend this business.

Great place to get your smog check. Really cheap & quick service. Will recommend to all my friends and family.

Wow! Great customer service! The owner is super friendly and chatted with my kids and myself with a big smile. The clean waiting room kept my kids occupied as they looked at all the pug items. We will be back and will be recommending this place to anyone who asks! read more

Let me say first I'm not a big fan of smog stations and going to mechanics. Because of past experiences I've always been a little gun shy on these types of places. However not only was the service fast pleasant I felt like I paid a reasonable price for my smog certification. And it was done on Sunday how great is that. read more

This place is great such nice and well spoken employees I felt welcomed the moment I got out of my car! Great atmosphere in the waiting room felt like I took a quick vacation to the tropics. read more

So happy to find such a friendly place to take care of our smog. I was in and out in 10 minutes. I will be back & recommend this store to all. read more

This is the ONLY place my husband and I ever take our vehicles. We always make an appointment and they have us in and out in less than 20 minutes. Just show up, hang out for 20 (we walk across the street and get a starbucks) and your done. They handle all the paperwork and the price is right. Kanh is an all around nice guy and a pleasure to see every two years. read more
