Schedule a Diagnostic Emissions Inspection in Chamblee, 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!

This is the best place you could possibly go to take care of your car! My family and I have been going here for over 15 years and we recommend them to everyone. Eric, Bryan, and Graham are the most trustworthy guys and truly care about their customers. We all love them and are so thankful we found them!!

October 12, 2021Came in for emissions and they exceeded my expectations! Saw headlight out, replaced it. Saw no oil sticker, checked it and put a little in it until i can get back in for change. While waiting you could tell these guys really care about their customers and the safety of their vehicles. Definitely will be coming back here!

April 26, 2022WOW!! An amazing experience! Traveled here from Kansas to apartment shop for my daughter who is relocating and my husband was unable to join A part was dragging under the car so we popped in to see if they could help.

June 18, 2022Able to fix issue with my 2011 truck other shops could not address- very hard to diagnose mechanical issue another reputable shops couldn’t figure out. Good prices, done on time, and with expert mechanics. Will have them work on all of my vehicles and highly recommended. Support a family owned business for a change!

After recently moving to the area, I had a vehicle emergency where my transmission needed replacing. Graham immediately took me in and was SO kind, professional, and direct about the costs; one of their kind staff members even drove me home after my car was dropped for repair so that I did not have to call a car service. They were so patient with me and got my car back to me in one day completely fixed and ready to go! I will never use any other automotive repair shop in the area! ABSOLUTELY recommend without hesitation!

Eric was amazingly helpful to work with. Great communication around the whole process. He was great about calling out things that could be done without being pushy about doing them. Would highly recommend!

February 27, 2021Very respectful, honest, and professional. I was having issues with my headlights, and they fixed it for a reasonable price. They do a lot to ensure that you have a positive experience, and that you're not wasting your money on unnecessary parts or repairs. Top notch service, A+!

November 4, 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.

December 1, 2020I live in Brookhaven and work in Duluth and pass dozens of auto repair shops on the route. I will forever go out of my way to go to McCullough. This is hands down the best repair shop I’ve ever been to. They are honest, kind, and treat each customer with the utmost respect. I’ll never take my cars anywhere else!

May 16, 2022A staff of gentlemen ready to answer every question with a smile and great knowledge. They not only gave me a good estimate but they completed the work a day early! I highly recommend McCullough NAPA Auto Care to you. You will not be disappointed by the care they put into your vehicle.

March 13, 2020I have used McCullough Auto Care for more than10 years. I needed a reliable auto maintenance service because I commuted weekly to Birmingham. One of the nice things about these guys is they listen when I mention an issue with the car, go over their inspection results of my car and review my bill in detail. I have never been disappointed in their service or the cost of the service I received.

This place is right by my house. I was really happy with the customer service. I was worried about affordability and turn over but they were efficient and I will be back for any future needs.

August 30, 2020My parents and I have been taking our cars there since the beginning. Great, hardworking guys. The only mom and pop shop left in Sandy Springs.

January 2, 2022I would normally recommend this business as I have been here a few times. I went there Friday for an oil change. However, I honestly didn't feel safe. They have signs that customers must wear a mask. There was only one employee wearing a mask themselves. All the others didn't have a mask on. I feel this is disrespectful to their customers. I understand it can be uncomfortable but it is essential during these times.

Eric at McCullough has been taking care of my family's [multiple] cars for over 10 years now. A Volkswagen, a Nissan, and 2 Acuras: They've done minor repairs all the way to major transmission replacements. Eric is trustworthy, honest, and tells you what really needs to be done versus what can wait. Their prices seem reasonable (although in fairness I haven't been anywhere else recently b/c I'm so pleased with them), they are timely, and always communicate what the car needs in detail. I can't recommend these guys enough!

September 19, 2019My 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!!!

Great 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!

June 10, 2021Would recommend to anyone that needs vehicle maintenance. They are the most honest and reliable mechanic service that I’ve dealt with. Thanks again!

February 16, 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.
