They have you stand just a couple of feet next to your car while the computer takes the readings & you are given a transcript of the results and they are electronically sent to the AZ DMV in case you lose your paperwork. Extremely fast & efficient.

Outstanding Service, Patience, and Customer Care! I want to…read morerecognize the outstanding service I received at ADEQ Emissions Testing Station M16 in Apache Junction. I brought my 2004 Mercedes-Benz C240 in for an emissions inspection three times. The vehicle initially failed because I had recently replaced the battery, which cleared the computer memory and the required emissions monitors were not yet ready. What could have been a very frustrating experience turned into a positive one because of the people working at this station. On every visit, the team was patient, professional, courteous, and willing to explain what was happening. I never felt rushed or treated like I was simply the next vehicle in line. I especially want to recognize the station manager, Sam. She went above and beyond by providing me with a website where I could find the proper drive cycle for my Mercedes-Benz C240. That information made a real difference. I followed the drive-cycle instructions, returned for my third inspection, and the vehicle passed. I really appreciated that Sam and her team didn't just tell me the vehicle failed and send me on my way. They helped me understand why it failed and gave me useful information about what I could do next. That kind of customer service can save someone a lot of frustration, time, and potentially unnecessary expense. After three visits, I can confidently say the excellent service wasn't a one-time occurrence. The M16 team treated me with the same patience and professionalism every single time. Thank you, Sam, and the entire M16 team. Your patience, knowledge, professionalism, and willingness to help are greatly appreciated. This is exactly the kind of public service that deserves to be recognized. I highly recommend the M16 location!

I'd definitely bring hand sanitizer and alcohol wipes next time. I'm fairly certain this will be a similar experience to any in the east valley, so I'd return to this one if needed for emissions testing again.
