Service was quick and efficient. In and out in a very short time. Probably the best time to go would be before noon.

BE AWARE!!! This testing station is by far the absolute worst emission experience I've ever had in my 60+ years of life. Avoid it all cost. Piss poor management, no communication, the middle of the day of the middle of the week and its's been a 2 1/2 hour wait and we're still 15 cars back. They said one of the machines broke down, but they weren't detouring people away from that line, no other lines were moving, and there was no communication with those anxiously waiting in our cars. Even worse...there was no way out of the lines to exit...customers were getting pissed. It was SOOOOO EXHAUSTING! Total chaos. I tried speaking to management and they were total jerks. I even told them I was going to leave a bad yelp review and his response was "yea, I've heard that every day for months"...HUH? So what in the heck does that tell you people? The only good thing was the people that finally got us through the processs were kind and friendly...but prior to that was a complete nightmare...AND it was 3 1/2 HOURS LATER!!! If I could give them a negative 10 stars I would. read more

Everything about this place is a joke from front to back. The wait times listed are never accurate. Today it's saying an 8 minute wait time, yet there are cars backed up all the way out onto 112th and stopping traffic and causing a hazardous condition. This place is ridiculously horrible and always has been, and probably always will be. Obviously run by idiots with no hope of ever improving. read more

Horrible organization, horrible customer service!!!! This place really needs a facelift. Someone needs to bring to attention how horrible the organization is here how chaotic the traffic is here how rude I mean very very rude. The employees are here. if the employees here don't like their job, they should go find a new one. They don't need to take it out on the customers. We are paying customers. We are doing what we are obligated to do by law from the state of Colorado. !! The state of Colorado really needs to get their air care facilities in order. This is absolutely ridiculous. The traffic is going to cause an accident there's going to be a fight. This is a horrible, horrible location. If you can go to another location, I suggest you do I live one minute away, so it's not convenient for me to go to another air care, Colorado!! Horrible, horrible horrible horrible all of them !! One in particular, his name is Ricky Ricky. Get zero stars for the day. Ricky is rude. Don't do it Colorado air care sucks Northland, Colorado. !!! The bathrooms are disgusting inside the building is dirty. Yeah I know it's an air car, but you could at least clean the toilets. !!! read more

Air Care Colorado - If you pull into the wrong line, they yell at you - Smog Check Stations Near Me - Northglenn, Colorado

Super quick service and kind staff! Everyone was smiling despite the long lines and they were very efficient. Great prices too!! Also I drive a pretty old stick shift and the staff was able to handle it great. I got there 10 minutes before opening and there was already a really long line, but it was handled very well. They got cars checked starting at 8am sharp! In total I was there from 7:50-8:50. Definitely some waiting in line/sitting, but just listen to music and make sure to block out a good chunk of time, there might be a long wait! read more

The rudest person that I have ever come in contact with works here . Heavy set guy, brown hair, and screwed up eyeballs. He is going to yell at the wrong customer some day. The two ladies that I interacted with, were very friendly. But this jerk is reason enough not go here. 1 bad apple. read more

Was really quick even with long lines, not sure why there's so many bad reviews. The employees were really nice and it was so quick once I got in the garage. read more

The people working here are lazy and have a horrible attitude brought my car in twice they made up some dumb excuse about not being able to service it the second time they said they couldn't get the traction control turned off and they gave me a paper to call a customer service number. Took it to a different admissions place the SAME DAY and they were able to do everything just fine, even tested it twice with it passing. These guys are liars and will say anything to get you out of their hair. I was also on a phone call and it apparently connected to the bluetooth of my car and my wife could hear what was being said inside of my car and all they were doing were sitting there talking shit about the customers, myself included, and cursing profoundly. not very professional if you hate your job that much then find a new one. read more

Wow, it was my lucky day! Went in on a Saturday hoping the weather would get temps above 15 degrees as it just snowed the day before. Took my chance and drove to the location around 10:20 because weather reported temps were about 21 degrees. Well, they were open and I was really happy that there were no long lines! I was able to pull in and waited less than 20 mins and I was out with flying colors. Woohoo!!! Fastest service ever that I've experienced. It was a good day. Service was good and reasonable. Hoping future encounters are like this. read more

Online wait estimations are completely wrong. Over an hour long wait at the "9 minute wait" Northglenn location. Also having one line for the most common age group of vehicles seems like a huge afterthought. read more

Don't mind all the bad reviews, most those bad reviews are drivers with older cars, no ac or radio, knowing their cars not in great shape and may not pass the test, and waiting to the last day to get there test done. all staff was friendly, 60 cars in front of me and I was in and out in 30 min! read more

The people at this location of very nice and work very hard BUT having over 20 cars idling for 45 minutes waiting in line seems to be defeating the purpose of having less emissions polluting our skies Got a feeling we need to think about this a little more read more

Air Care Colorado - More stupidity to pollute the world - Smog Check Stations Near Me - Northglenn, Colorado

I thought my 1st time dealing with state operated station would be a nightmare. I was sure wrong. They opened right on time, got me right to the lane I needed. Everyone was friendly, informative and had me out of there in 10 minutes. The Boulder location is great. read more

Place is supposed to be open at 8am. it's 9am entrance still blocked, workers standing outside doing nothing, line of cars going down 112th wrapping around erma, totally impeding traffic. place is a mess. been this way for years. makes you wonder who hasn't gotten the picture yet on how to fix. Pathetic. like other people don't have things to do. read more

Took my truck here a little before closing the staff was supper rude because they where mad I showed up at that time, when my truck was ran I noticed they were revving it a bit while running while on deceleration witch I've had happen before causing the vehicle to fail I bright this up to the manager who said no that's not true and he would not test it unless I paid witch of corse I was not going to do. I tried calling the office with no repose don't take your car here they find ways of making it fail by testing outside of the norm or how they are so-pose to, i ended up taking it to another location where my vehicle pases first try nothing new done to the vehicle same gas and same hot temperatures stay way !!!! read more

Was in and out in 20 minutes. The two guys that helped me were great. One did the smog and the other did the vin check. Both were very professional. read more

Avoid this one. So called manager Jen is very rude, arrogant, unprofessional, lacks customer service skills, and has zero knowledge of vehicles. If your car is old and a work in progress she believes it is ok to laugh and poke fun of it. If one of the crew does not agree with her she yells at them in front of customers. This is a person that should not be a manager and not work with the public. Very ugly person and attitude. Waiting on a call back from her boss and hope she Is fired. Here is a tip for Stupid Jen, some older vehicles before fuel injection had from the manufacture what is called a vented gas cap. So again Stupid Jen it will not pass a pressure test it is vented. You really are a sorry excuse for a manager. read more

Quick & cost effective! Was in & out within 30 minutes for both a smog check & VIN inspection on 2 separate occasions. Blonde woman working front desk was SO pleasant & helpful! Really appreciated her! read more

So fast and efficient even during covid! Got in and out in less than 30 minutes. It was a lot faster than other sites I've visited.

Fast friendly service! Not the most relaxing waiting room but you can observe the process from the waiting/observation rooms that have plenty of Windows. The small TV at the end of the exit door where you will be called when your vehicle is done, plays informative air purity information as well as basic preventive maintenance recommendations. Over all a painless process that will get you on your way if you arrive early morning 0800 opening! Note: pay attention to what lane you get in! All wheel drive vehicles have their own lane! Happy safe driving! read more

See all

They burned up the parking brake by running dyno test without releasing it. Then they lied about it. Now I have to get it fixed and file a claim against them. read more

This place is a joke. Manager is sooo unaware of of what is going on. Some people working and cars moving, while others are just chatting. Not organizing cars to move evenly and not fully utilizing their lane capacity. Try to reach out to someone to get a better understanding of the situation and they ignored us. If you can avoid this place, do so. read more

Air care Colorado emissions is great! Every time I have gone there to get emissions done, I never have to wait any longer than 5 to 10 minutes at the most. They are also very friendly and efficient. They have a decent waiting area that is enclosed. You pull your car up to the designated garage bay, Leave the keys in and they will take care of the rest. When they're finished they will come get you to finalize the transaction. They would benefit if they had vending machines available to the customers. However, I highly recommend air care Colorado! read more

After waiting until 1 day before my deadline, I went to the Northglenn Emission Center. There were 30+ in front of. Because of the efficient, hardworking and friendly staff, I was out in under 40 minutes. I highly recommend this station! read more

Worst experience ever! I waited a half and hour to be yelled at and refused service. Instead of coming over ame letting me know I'm was In the wrong lane the Awful man who works there began screaming at me and then refused service! I have never been here before and simply followed the cars in front of me. Awful! I will be filing an additional complaint! read more

Fast efficient good prices what more can you ask for? There was a fairly long line when I got there before it even opened and I say they got through at least 15 people including me within 20 minutes. Insane read more

I'm from out of state. Need better signage if you just need a VIN verification. Waited 30 minutes in the emission line after employees are barking orders as to which lane to be in, only to be told I can't be in those lines. The VIN inspector was nice and explained that they are understaffed and are restricted in signage read more

For something you're forced to do, this location isn't a bad one to select. I went through on Wednesday around 1 PM and there wasn't a line at all. Brenda was helpful. My gas cap failed the test, but they give you a coupon for $10 off at NAPA, which made it a $3 repair. I'm glad they modernized and are now accepting credit cards, something there wasn't an excuse to do previously, to be frank. There's a little snack machine and pop machine if you get hungry during heavier business hours. If you are claustrophobic, you may wish to avoid as the narrow corridors you have to wait in while your car is being tested as you may find them uncomfortable. read more

This place is a joke, you people in line waiting for more than 30 minutes then some else shows up and they pass them right away instead of having them wait. Also there was 4 lanes open and they have everyone in one lane. The technicians are you standing around and horse playing instead of having people go thru the other lanes.. where's the manager for this facility. read more

Perfect. I came from other state this month from Idaho and so we need the emission test before title my cars. Yes! I felt so much comfortable here. Feeling as I am at Five star hotel.. Very kind people and staffs. But... I don't want them to be more busy due to my comment. :) Enjoy your life ! read more

Air Care Colorado - I found here just by googling. But fast line and great service ! - Smog Check Stations Near Me - Northglenn, Colorado

The staff here have always done a great job. Their Covid protocols are safe and efficient. Never too long of a wait, which is always a good thing. read more

These people are so nice! I passed! no line and it didn't take long at all. I love all the signs noting that they have to honk but aren't honking so people will come get their cars. read more

Everyone was very efficient and to the point. It was cool to being able to see my car being tested from the waiting area/box.

The whole process was really easy, i was in and out! Ive been here twice on two different occasions and noticed the second time had a long wait this is no means their fault if you're on a time crunch try going at a different time. read more

Great experience, great service. I was in and out within 15 min. Granted my car is awd and there's a separate line, but moved quickly and staff was very nice (on a Monday no less) read more

Air Care Colorado - Smog Check Stations Near Me - Northglenn, Colorado

The wait wasn't too long and everyone was friendly. I just moved here from another state so I didn't know that my AWD Subaru needed to be in a specific lane, but they were way cool about it and moved my car for me. My wait would have been even shorter if I had read the sign correctly :) **Also, they take credit cards now! read more

A technician waved me forward, and an employee berated me, told me to learn to read the sign that said stop here, and told me to go somewhere else. read more

I went here for a VIN verification, and accidentally (by my own fault) ended up getting an emissions test when I didn't need too. The woman who helped me was so incredibly nice, and helped me understand where I needed to go for just my VIN. Then the woman who helped me get my VIN verification was ALSO incredibly nice and helpful. They made something I dreaded having to do, a good time. read more

Feedback: Address: 1950 E. 112th Ave., Northglenn, CO 80233 Lanes: 7 Phone: 303-456-7090 Hours of Operation: 8am to 5:30pm (M-F), This is the 3rd time I have had troubles with your station regarding the administration of the actual test on my 1991 Vanagon (4 speed Manual) 2 years ago the driver killed the engine in the middle of the test... and then it failed. I drove the vehicle around the block and came back and the next driver knew how to drive a stick and it passed. However fast forward 2 years later to 2014 and the driver killed the car AGAIN 6-14-2014 and then continued with the test anyway and it failed. They would not test it again with a new driver. I took the Van to my mechanic and he assured me there was nothing wrong with the engine... Just like there was nothing wrong 2 years ago when it failed and then passed the same day. Anyway, I come in today and made sure to request that someone experienced administered the test. I was told the girl doing the test was one of their best drivers... I find this hard to believe since the previous time I came in 6-14-2014 and it failed the girl who handed me the paperwork and jokingly told me she had just started working there so go easy on her. I hadn't even said any more than hello to her and she says this to me. Yet she was the same new girl doing the actual driving test today. She is one of your best drivers? What kind of operation you running there anyway? Is it Standard Operating Procedure to lie to customers like that? I tried to record this latest test on my phone video but was rudely demanded to stop and delete the video. So I stopped and deleted it. Then I witnessed the new girl driver kill the test 3 times and then she burned my clutch. The entire area was smoked out from the clutch smoke coming from up under the back wheels where the clutch is on the Vanagon. Too bad I was not able to record it... But y'all have this on video I was told that's why I agreed to stop recording and complied with the deletion of my video. SO now I request a review of the in shop video so you can verify the smoking clutch damage that your driver caused to my vehicle today Around 15:30 to 16:00 7/7/2014. They stopped the test and did not finish it and pushed my vehicle out to the parking lot. I complained that they burned my clutch but they denied it and said it "overheated". Anyone who knows anything about clutches knows what a burning clutch smells like... It's like burning rubber. That's what it was... Your people burned my clutch. So I drove my van home but noticed the clutch was slipping. So now what? I guess I'm screwed out of my test that I already paid for... now I'm looking at some pretty hefty repair bill to fix the damaged clutch thanks to your testing site. I've been going to that same testing spot since 1996. This lack of service and rude treatment is very disappointing to say the least. Completely unsatisfactory is what this is. read more

Staff was wonderful, quick service, face covering work, well priced! Great experience overall!
