Schedule a Diagnostic Emissions Inspection in Johns Creek, Georgia
Failing an emissions test can be frustrating. An emissions test aims to measure the levels of pollutants in your vehicle’s exhaust. Every engine produces emissions, but releasing too many harms the environment.
Schedule a diagnostic emissions inspection, and our technicians will start by visually inspecting your vehicle. They will simultaneously run a diagnostic report that shows your emissions output. Once complete, we will know exactly what needs to be repaired, if anything. We suggest scheduling your diagnostic emissions inspection four to six weeks before your emissions test.

Reasons For a Failed Emissions Test
A failed emissions test can come as a complete shock for a driver. The causes of a failed emissions test can range from a loose gas cap to an extensive exhaust system issue. Here’s a comprehensive list of some reasons for a failed emissions test.
- Engine issues and check engine light. If this is on, you will always fail your emissions test.
- Overdue oil change
- Faulty oxygen sensor
- Damaged exhaust system
- Loose or cracked gas cap
How To Avoid Failing Your Upcoming Emissions Test
The State of Georgia suggests vehicle owners get their vehicle’s emissions tested four to six weeks before the registration renewal date. The extra time will allow any repairs to be made before your vehicle’s registration expires. We encourage you to consider our scheduled maintenance plans, where repairs and services will be made to your car as needed. Our technicians will be more aware of issues as they pop up because your vehicle will be inspected on a scheduled basis. Areas like your exhaust system will be inspected more frequently as well! This can help increase your chances of passing your emissions test!

They diagnosed and repaired my car in time for my trip. Car works great! Eric provides excellent customer service even when he's got a ton on his plate.

May 10, 2022I may have written one other recommendation in my of 50 years, but after doing business with Eric McCullough for 35 of those years it is time to write another one. He maintained and serviced my auto's, my wife, kids and employees for 32 of those 35 years. He has stood behind the work on everything he and his employees have done. He operates his business with great honesty and integrity. I highly recommend doing business. with McCullough

May 4, 2021McCullough has been my family's go-to mechanic for decades. Don't know what I would do without them - just a super-nice family that will take care of your cars. Their service is important to us because once we get a new car, we like to hold onto it for years (10-12). Highly recommend.

I know for me one hard thing about choosing a mechanic is brushing off all previous notions I have about mechanics Potentially not treating my car how they would treat their own car. This place has done more than exceed my expectations. I got a phone call for every update, I got a thorough description of what was to be done and what was wrong, not only that, but where the dealership said it would take them two weeks to fix my car, these guys did it in less than 24 hours. I have never been happier to spend $300 in my life. Anything I need in the future, you can be sure I’ll bring it here.

September 10, 2020I found my new home for car repair. Eric was very nice and honest. We definitely be coming back! Thank you for the excellent customer service.

October 21, 2021We have been depending on McCullough's at least since 1997, when we purchased a home only a few blocks away, walking distance really. Had our emissions test a few days ago and want to acknowledge Jack, who completed the tests quickly. I asked him to determine why the backup camera was not in the proper position. It took a bit of time and ingenuity to get everything right. Thanks Jack, for the excellent service.

Very honest mechanics. Eric kept me in the loop with my cars progress. I got the car back in a reasonable amount of time considering the work that had to be done.

January 30, 2020I own and automotive repair business in Jacksonville, but my wife lives in Atlanta and needed tires for her car, so I know good service and fair pricing in this industry. I chose McCullough because of their good reviews and they did not disappoint. They were very professional and took good care of my wife. I would highly recommend them and will continue to use them for her service needs.

Had experienced front tire damage hitting metal debris on I-285 just before Rosewll exit. Immediately exited on Roswell and saw NAPA sign and pulled in. Place was busy! But got attention immediately by Jeff service worker. Got tire off my car no waiting. Wow! Determined rim bent but tire still good. He could have sold me a new tire and i would have not known better. So appreciative. Then met with Eric McCullough and quickly arranged to have rim fixed. I decided on new tires for safety and were worn. Eric got me great deal on tires and had my car fixed SAME day. Eric runs a super customer-focused operation. Kudos! Bruce Fike

August 1, 2020My truck broke down when we got to Atlanta on the way to Disney world. A local stopped to help us and recommended this place. This place got me in and got the radiator fixed for a very fair price and on our way the next day very quickly. I was so impressed and it's no surprise they are very busy. Thank you so much and my family all got to the resort and is having a great time!! These people are great and will get your vehicle fixed for a fair price. Plus, you get Napa warranty all over the country at least I did on the repair I got. Please support them!!!

This shop is the best. They did everything they could so I would have minimal time without my car such as having all parts ready before they scheduled the repair. They are super nice and no surprises on price. They opened up my bumper and found a part was damaged. They could have left it the way it and no one would have known but they were honest and did the right thing. I recommend 100%.

July 24, 2019Brian and the team were fantastic with handling my issue. In fact they discovered a major error which occurred when I had my last oil change done at a quick oil change place, which turned out to be the cause of my issue. They took pics of it and wrote out an explanation for me to give to the previous oil chance place. Because of their extra effort, I am getting reimbursed for the error. I highly recommend Brian and the team!

I had a check engine light on Saturday afternoon, ended up being an engine coil pack needing to be replaced. It was obviously super busy and I knew I would need to leave it until Monday to get looked at. Staff was very informative and communication was excellent. Got it looked at Monday and ordered necessary part to come in the next day. Went ahead and did the spark plugs as well since I was nearing 60k miles. Picked it up after lunch with no issues. Seems like they do really well with the small space provided and very busy area right off 285

July 21, 2021McCullough Auto Care has earned our trust over the past two years by consistently giving us quality, reliable repairs at fair prices. The staff is polite, knowledgeable, and never tries to talk us into things we don't need or want. We will continue to trust McCullough for all of our repairs.

October 10, 2021Great customer service! Eric and team did an awesome job coordinating their busy schedule with the schedule of my girlfriend and myself so that we would have a car during the work week and then trade off cars when the other was ready. They are extremely friendly and it felt like they had us as the customer in mind. Highly recommend!

Always extremely professional. Willing to work with customers. Sadly, car repair is expensive but they have worked with me. Graham has been extremely helpful with issues my daughter was having with her car while we were at another mechanic in the area. We asked on Nextdoor for recommendations and McCullough came up numerous times!

May 14, 2020I was so impressed with these guys!! Family business and the guys are professional, efficient, and personable. They got my part quickly and fit me in so I could come while my kids were at school. They went the extra mile (no pun intended) to consult with another auto body shop to make sure the repair was stable. I will be coming back for all future auto needs and will recommend them widely.

This place is a life saver. Great communication, great service, and very professional people. Eric worked with me through my whole repair. Kept me updated through out the process and fixed the problem on my car at a fair price. I will definitely make this my new place to go for all my car repairs and maintenance needs, along with sending my friends their way.

My vehicle was on the verge of breaking down while I was in Sandy Springs for work last week (I live in a different town), and my boyfriend had determined that it was a problem with the alternator. He helped me find McCulloch Auto Care, which was right down the street. We'd noticed the good reviews, and we took a chance! The staff is super friendly, professional, and kind. They were able to confirm our suspicions about my car's specific issues, and took us as soon as they could. I was so impressed with their customer service. They really went above and beyond to meet my repair needs, had a fair price, and worked quickly to repair the issue. I almost wish I lived closer just so that I could have my car serviced here more often! Great family owned business.
