Schedule Buick A/C System Recharge in Atlanta, Georgia
A lack of refrigerant in your Buick’s 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 Buick. We’ve been in business since 1969 and have ample experience repairing air conditioning for any Buick model, including the Encore, Envista, Enclave, and older models.

We had an issue with a splash shield dragging and overheating. We are heading back to Kansas this afternoon. They were able to fit us in despite being super busy & do a quick fix and sent us on our way in 10 minutes. So kind and amazing service!

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.

May 10, 2022I 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 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

August 29, 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.

January 7, 2021A 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!

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!

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, 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!

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.
Walt Anthony
August 6, 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.

September 10, 2019I 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.

I 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, 2021My experience was surprisingly excellent. I was greeted immediately before I could actually get out my car. Eric was professional and friendly. Eric Followed up with me has promised. I really like that Eric shares real honest timing/wait expectations.

July 20, 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, 2022I 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.
Reid Ramsay
November 4, 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.

Able 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!
B. BB
February 23, 2021I 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!

Signs Your Buick Needs Air Conditioning Repair or Replacement
Use the following signs to help determine if your Buick 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 Buick 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.
