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.

July 19, 2020Eric was amazing from start to finish. I chose this shop for my repair based on previous reviews & I'm glad I did. He made sure to, in my opinion, go above and beyond with his politeness, as well as helping to make the process smooth and to try to save me as many coins as he could, while still getting done what was needed. Very happy with this visit

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, 2020I received great service from this location! I called them about replacing a serpentine belt and they got it done for me the very next morning. It was quick, and cheaper than some other places that I had called for the same service. Eric and his team did a great job, and they were very nice! I will definitely return for any other auto repair I may need in the future.

Would 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, 2021Have 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!

March 16, 2022McCullough 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 have an older vehicle so I see these folks more than my wallet likes. They are amazing, friendly, people that are a pleasure to work with. I can't recommend them enough.

November 4, 2020What more is there to say? These guys are amazing. Their service is very thorough and quick. I was so worried about the cost of my repair but Eric and Brian put me at ease with their extremely reasonable prices! My truck is running like it's brand new again and I can't thank these guys enough!

March 1, 2020I 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.

My 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.

August 6, 2020Eric and his staff were great and helpful. The pricing was fair, and they let us know every step of the way what was wrong and what needed to be changed.

June 28, 2020Eric 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!

Extremely helpful, knowledgeable, and professional people. Would definitely go here again if I was in the area and needed them!
Brandon Holdeman
October 2, 2020Came 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!

My 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!!!

September 16, 2019They 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, 2021This has to be the best shop in town! When I got my car fixed the last time, It drove live new. I've never been so happy to get my car fixed in my life. They were very friendly and honest. This will be my go to place from now on. Not too far from my house which is a huge plus but even if it were, I'd be game to making the trip. Thanks for being honest and giving great service!

Quick 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 22, 2021Eric and Company are a first class operation! They get it right the first time in every time! They will pick me up and drop me off to make it 100 times more convenient. They treat me like family and look after my best interest not just their bottom line! These are the kind of people that I value doing business with

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.
