Emissions testing service near Chicago, IL

I was stranded 50 miles from home and got my car towed here, I was a little nervous not knowing anything about the shop or the area. John was very nice and assured me that they would find out what was wrong, I wondered at what cost..The car was looked at and the cost was very reasonable, being a woman I was concerned they were going to try and overcharge me because I had no other option but to go there. Even though I live so far away I would definitely bring my car here again for service, a nice honest mechanic/repair shop is hard to find but this place rocked!

Dan is the man. He is one of the guys you see first and he is always smiling. He is very nice as well as very knowledgeable in the automotive industry. He won't try to sell you something you don't need. Very fast oil change and I got a text from them when it was all ready. Go here for a hassle free job. Highly recommend this place.

I have high expectations for anyone who works on my vehicles and Rennology was up to the task. They are very professional and completed the work in a timely manner.

This is a very convenient location for me,and my family has used Frank's for years. The service is great and the prices are always on point. I really like being able to drop off my car, then walk across the street and catch the metra into work.
