McHenry Smog Center - Pug lover! - Smog Check Stations Near Me - Modesto, California

Wonder why Mchenry Smog gets so many 5 star reviews? It's because Khan runs a great and honest business. Raquel in the office also is smart and does a great job. Make an appointment and see for yourself. I will never go anywhere else! read more

I got screwed by another smog shop so I took my truck here and explained to the tech what was going on. He hook my truck to his scanner and told me it's not ready for smog drive some more, I came back and he said it's still not ready come back Monday. He check my truck twice for free. That speaks volumes of what type of shop this is. I'll never go anywhere else again. Highly recommended read more

I tried this company due to Yelp. Was not disappointed. Made an appointment and was in and out within 15 minutes. Couldn't believe it. Plus, was affordable. Will go back. read more

I made appointments for two cars at low prices. The service was fast. The staff is super.

Came on Saturday without appointment. Great price. Wait was about 45 minutes, a little long. Staff did a good job, suggested coming 7am next time for shorter wait. I would definitely come back. read more

Very quick service. About 40 dollars out the door. I barely had time to sit down before they were done. There was no one in the bay before men read more

Awesome service called over the phone they said come down . They did everything in about 15 min and I was on my way. Everyone was super nice

These guys are great! I was in a time crunch to get my car smogged in order to get registration done on time. I stopped in at 11am without an appointment and was squeezed in at 12:30. I had enough time to grab some lunch, stopped back in and was out by 12:45. Great and quick service, I felt very well taken care of. I will definitely be coming back to McHenry Smog Center! read more

Great customer service. Called at 4:05 on a weekday and was able to make an appointment for 4:30. I expected to wait but they really meant it when they booked an appointment. In and out within 10-15 minutes. The owner is very personable and strives to keep the customer happy. Too bad he does smogs because I only need those rarely. :) read more

They are so effecient and fast here that you can actually drive and ten minutes later drive away! I even forgot my wallet and luckily they supported google pay. I've been here on a few occasions and got the same service. I recommend them fully if you're looking for professional rapid service. read more

Kanh is the best...honest and cool. Don't even think. About going elsewhere...been there done that. Price is right too!

Great price and very efficient. Made an appointment the next day and was done in 20 minutes.

McHenry Smog Center has been consistently good for me during the past several years. Friendly, professional and efficient are descriptions which can be applied to both the shop and the office. read more

I went in this morning at 8:30 when they opened, without an appointment. They explained to me that there was an 8:30 appointment and that I'd be right after. By 8:49, I was out the door. It was so fast and convenient! The lady at the counter and the guy performing the test were both so polite and helpful. I definitely recommend this place and will be back next time I need a smog test read more

Better make an appointment before coming!! Walk-ins are put to the end of the line. $31.75 test fee and $8.25 certificate fee plus tax.

Best smog check ever! Great customer service, fast, and honest! Thank you and God bless to the front desk lady and the owner who did my smog!!! I will be recommending them to everyone read more

I would recommend this place to anyone/everyone. Quick, efficient, pleasant service...what more could you want? Our family will continue supporting this business. read more

Exceptional! Super friendly and excellent communication. Hand sanitizer at the counter which is fantastic.

Had a great experience getting two of my cars smog tested here. The receptionists were both very kind and accommodating. My appointments were taken care of quickly and easily. Would definitely recommend. read more

Incredibly friendly staff! We were able to walk in and get our smog check started immediately. They told us it would take about 15 minutes but it didnt even come close to taking that long. For a place that says appointments recommended, they are incredibly accommodating to walk-ins. They've got my business in the future! read more

Best price and quality of service in modesto. Great courteous and friendly. Honest with their quotes

So, I've used McHenry Smog Center once before, and if I based my review solely on that previous experience, it would have been a 5 star. Unfortunately this past experience has left a sour taste in my mouth, one that may lead me to find another location. The issue this time is one of poor customer service and understanding. I had my car fixed and brought it to this center to get smog tested. I thought I had driven it enough for the computer to reset, but it seems I didn't and the car failed the test. Now, I had called ahead of time and explained the situation to the receptionist, and even reiterated it at drop off. At no time did the receptionist verify that I drove the car enough NOR offer the opportunity for them to check the computer first to make sure it was ready to be tested. In fact, it wasn't until after I came to pick up the car and paid the full price that she offered this tidbit of information. Now I can bring it back for a retest...at nearly the same price (savings of about $8). I just feel that, knowing I just had it fixed, she could have offered the computer check first and saved me some money. Instead I'm left with the impression that all they care about it the money and not building a customer relationship. I have several cars, and I am of the opinion none of them will be tested by this center. Nor would I recommend them to anyone without first offering the caveat that they better make sure their car is set to pass before they sign up for the test. TBH, my frustration could have be avoided if they just, as standard practice, asked if the car had been recently serviced or lost power before agreeing to the test. Thus giving their customer the opportunity to save some money by not paying for a pointless test attempt. Or, at the very least charging a $5 charge to check the computer before actually administering the test. I would have been fine if they checked it, saw it would have failed, and just charged me a minimal (like $5) fee and told me to bring it back after the pre-test conditions had been met. I guess, like all things, caveat emptor. read more

I was visiting from out of town and decided to get my smog check here. I was not let down. Excellent timing, service, and great price.

When the gal told me 10 minutes I thought she misspoke. I was right, he was done in 8. Quick clean professional. The way business used to be. I will repeat and have already told a couple of friends to go there read more

Great prices. Excellent service. Made an appointment, in and out in about 15 mins. Highly recommend going here for your next smog!

Fast service. Very friendly. The tech on Saturday stays incredibly busy. He gets through car after car and gets people in and out very quickly. He's really good at his job and as busy as he stays I'm not sure he ever takes a break!! Lol The receptionist at the desk is very kind and helpful. I've only been here twice but I've been very pleased with their service both times. I will definitely continue to use these guys for all of my car smog needs!! read more

Kahn is very experienced and trustworthy a rare quality these days. I take all my vehicles there and have been very happy, he has done my 4 Cars every time for the last 8-9 Years read more

Smogged two cars, had a great experience. In and out in no time. Fellow animal lover so I knew I could not go wrong!

Had me in and out in about 15 minutes like promised. And best part I paid 40$!! I highly recommend it to get your smog check here! Super friendly and helpful will be returning here with my other cars. read more

In and out with Smog passed in less than 10 minutes!? And lowest price! Can't beat that

I kept putting off getting my car smogged, but once I took it here, it was very fast and painless. The woman at the counter is very friendly. Top notch read more

The only place I will ever come for Smog in Modesto. It's quite and very quick. We had a little snafu with my credit card that we were unsure how to fix while I was there. The woman at front desk called me a few hours later to let me know she looked into the problem and fixed the issue! Great place to get your car smogged! read more

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. . read more

Way above average smog check place! Clean and welcoming environment with friendly service from the lady at the counter. Fast service from the man in the back. Car was in, passed, and out within 10 minutes. read more

This is the only place I go to get the cars smogged, regardless if it is a test-only year or not. The owner and his wife are terrific examples of how and why small businesses thrive. They're honest, do great work, and the price is right. I'm happy to hear that business is going well for them. Some years you could just drive up and be seen; now their calendar fills up fast. One of the few places around that really deserves 5 stars. read more

Khan is the bomb! I was referred to McHenry Smog Center by my wonderful ( by the way the best) mechanic Doug at Central Valley Authohaus - I mention that because my mechanic knows how much I take care of my BMW and that I won't take it just anywhere for any of the services required for my vehicle. My sister also has taken her car to McHenry Smog Center and was very pleased with the service as well. She knows how picky I am and said Khan and his wife are very nice and are all about taking care of us as customers. Khan was friendly, knowledgeable, fast but STILL efficient. His son Brandon was very polite and processed my paper work when I was all done. the most convenient part for me being the commuter that I am during the week is Khan is open on Saturdays - so while I can't always make it in during the week he squeezed me in on a Saturday. I would never take my car anywhere else when it comes to smog service - thank to Khan and his family for making me feel like a regular when I walked in. continuing to wish your business much success and praying that it continues to prosper. your happy loyal customer, C.H (BMW 330 CI) read more

This place rocks the girl in the front office is so nice and I really appreciated all the help they gave me when I came in to do my smog. I would definitely recommend this business for anyone who needs their smog done!! read more
