Schedule Mercedes-Benz A/C System Recharge in Atlanta, Georgia
A lack of refrigerant in your Mercedes’ A/C system will result in a lack of cold air through the vents. If you’re experiencing warm forced air when you turn on your air conditioning, it could be because of low refrigerant levels. An A/C system recharge is quick and helps pinpoint the error’s cause. Our ASE-Certified technicians will drain your air conditioning system of any existing coolant. Afterwards, we will replenish the system with fresh refrigerant. If the system still blows warm air, we will know the issue is not due to a lack of refrigerant.
McCullough NAPA Auto Care staffs ASE Certified technicians with the experience and technology to properly diagnose any A/C system issues you may be experiencing with your Mercedes-Benz. We’ve been in business since 1969 and have ample experience repairing air conditioning for any Mercedes-Benz model, including all their sedan, SUV, Wagon, Coupe models, and more.

I have known Eric and the facility for over 30 years. The service from both a customer and repair stand point is excellent. You can expect to be treated with a high level of professional performance, and courtesy.

January 23, 2020Eric has been my service manager for years. He is always professional and easy to deal with. He goes out of his way to take care of your needs and makes accommodations to the customer when needed. They will ferry me and my car to and from their shop (I live within blocks) and I appreciate that very much. Everyone at McCullough is nice, friendly and helpful.

May 2, 2021Eric 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!

October 2, 2020Have been going to McCollough’s for decades! Once I found them, I knew they were honest and professional. Not often one can say that about an auto repair place. They have helped me keep my older vehicles safely on the road for longer than I could imagine. I have always been treated with respect, no matter how large or small the issue, which is excellent and reassuring for an older woman.Highly recommend them!

Brian 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!

February 3, 2022They figured out the issue with my Pathfinder and made the repair quickly. Eric is very thorough and kept me up to date the entire time. This was my first time using them but I will use them again!
Michael Meyer
October 21, 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+!

May 16, 2022I 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.
Erik Davis
September 10, 2020Great 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!

I 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.
John Greenfield
October 21, 2019I have used McCullough for maintenance on my prior vehicle and received great service. Recently I had to repair my front bumper - I received an estimate for repair services that was reasonable. The estimated turn around time was less days than other auto shops. The best part was, the staff (Graham) was accommodating with my schedule and the repair was completed as expected/on time. The work completed was great. I absolutely recommended McCullough for auto care services.
Jessica Astrid George
February 23, 2021I 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.

April 26, 2022My experience here was great! Fast, curious, and fairly priced. I didn't think a repair shop like this existed. I'll be a lifelong customer.
Walt Anthony
August 6, 2020This 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%.

Graham was great and was up front about everything that needed to be done. My son's jeep went down on the Saturday before Memorial Day and they had him ready around 1pm that Thursday. Quick turn around in my eyes. Nice employees, everyone was cordial and friendly.
Tim Lawrence
June 4, 2021Able 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!

February 23, 2021I do not know if I can type out all that I want to in this review but let me say this. WOW!! Being a single father with a busy schedule I cannot tell you enough how grateful I am for Eric and his team! I have been taking my vehicle to them for over 2 years now and I would not go anywhere else. The honesty, timing and keeping their word every single time is simply priceless! They have saved me so much grief because of my current situation. For all you single fathers out there...these guys got your back! I only have one vehicle and my son and I depend on it being in the best running shape possible. Eric and his team go out of there way EVERY-SINGLE-TIME. During these special times where its harder to get even the simplest things done, that has not slowed down this business. They still give 110% with every customer and are sympathetic to their customers unique situations. People, don't look any further for a shop that you can trust and count on. You will simply waste your time and find no better service in Atlanta. Eric, I want to thank you from the bottom of my heart for everything you and your guys do. Having open and honest communication with you is always a pleasure. Folks lets do our best to keep these guys busy!! They deserve everyone's business! A++++++

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.
Michael Brown
January 30, 2020A 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.
Byung Ham
March 13, 2020I really cannot count the number of times these brothers have taken care of me, my family and all our various vehicles. We have been loyal customers for more than 20 years! They have done everything we have needed on cars, trailers, used car evaluations for purchase, tank drops, and all the basics. They are very trustworthy and will give you a honest answer on everything and a reasonable estimate on what it will cost to resolve it. They are super busy, so plan to wait a day or two longer than you might somewhere else, but it is worth it!

WOW!! 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. They were so kind and helpful. Restored my faith in this world. Good people do exist!!
Angela Drybread
June 18, 2022Quick and excellent service. I was turned away at my regular mechanic because he said he didn’t know how to do a transmission fluid change. This was my first time ever going to McCullough auto care, and I was very happy with my service. They were able to see me immediately and were patient with me considering the circumstances. Eric was great, and even matched the prices of another mechanic down the road. I will be back! Would recommend!

July 1, 2020This 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.

Signs Your Mercedes-Benz Needs Air Conditioning Repair or Replacement
Use the following signs to help determine if your Mercedes-Benz needs air conditioning repair service.
- Air conditioner only blows hot air. There are several reasons why A/C systems may be blowing hot air. The most common is a lack of refrigerant. This is the easiest fix. Refrigerant causes the air in your system to run cold. Another reason for hot air could be mold or mildew within the system.
- Air conditioner blows cold air sporadically. A lack of refrigerant or a broken part can lead to a decline in cold air performance. Over time you’ll most likely be able to notice if your system slowly starts blowing warm air. Our technicians thoroughly inspect the A/C system. Once the issue is found, we get to work.
- Air conditioner makes unusual noises. Air conditioning systems are designed to be quiet. Noise and squealing may be the result of a faulty compressor. The compressor is what pressurizes the refrigerant so that it can flow through the vents correctly. A/C systems need regular maintenance to fix any loose parts over time. Consider having your system inspected with every oil change.
- Air conditioner emits a strange odor. The air coming from your Mercedes-Benz air vents should not smell musty. Bad-smelling air could be the result of an old air cabin filter. These filters are cheap to replace. Another cause for foul odors could be mold and mildew. Built up in your system, these microorganisms can grow and produce odors you’ll want to have taken care of quickly.
Our ACE-Certified Technicians can determine the root cause and give your system new life, no matter your A/C issue.

What To Do When Your Car A/C Is Not Blowing Cold Air
It’s a situation that nobody wants, but likely everybody has faced. You get inside your car, only to find hot air blowing from the A/C vents. There is nothing worse than a car A/C not blowing cold air. The good news is that there are a few common reasons why this may be happening.

Why Spring Is The Best Time To Schedule Auto Air Conditioning Service
A broken air conditioning system is horrible, especially when you’re stuck in traffic and dealing with the summer heat. While annual air conditioning inspections are recommended, we believe that Spring is the best time to schedule your air conditioning service for your car. Doing so will allow your A/C system to work at full capacity during the summer months.

Why Isn’t My Air Conditioner Blowing Cold Air?
Your air conditioning system uses refrigerant to create cold air. The most common reasons why your vehicle’s air conditioning system would lose its cold air will have
