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.

We 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.

November 21, 2021I 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.

July 13, 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

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.

June 4, 2021I 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, 2021I 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.

I 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++++++

April 29, 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.

Wow! I am so impressed with the service I received. Having moved here from Nashville I was nervous about finding a mechanic! These guys are BUSY but they treat every customer like their priority. I got my car repaired within two days on a weekend! Prices can’t be beat and I was getting phone calls with detailed status updates. Amazing service. Really compassionate. Please doing business! I thought I was going to have to spend thousands fixing the plate that was dragging under my car but I got it fixed for under $200! Thank you!!!

I 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!
Joshua Brown
February 18, 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.

I 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.
Ashley Sprague
January 11, 2021I have used this company twice and was VERY impressed both times with the honesty, knowledge, and cost-effectiveness of the mechanics that I worked with. They were upfront with me on what I needed to do now vs what could wait, showed me where I could save money, and worked with me to make sure I had my car finished before I needed it that weekend. Again, very very impressed. I wouldn't take my car anywhere else in Atlanta.
Anon Emus
September 10, 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

McCullough 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.

December 3, 2021Good, honest, and fair shop. If you are in sandy spring, I would not go anywhere else. Family owned and operated - take care of their customers and their crew it seems. 6 stars

January 23, 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!

Have 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!

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.
