Schedule GMC A/C System Recharge in Atlanta, Georgia

A lack of refrigerant in your GMC’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 GMC. We’ve been in business since 1969 and have ample experience repairing air conditioning for any GMC model, including the Canyon, Sierra, Terrain, Acadia, Yukon, and more.

    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!

    Eric 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

  • Out of town for work and needed an alternator changed immediately and McCullough's was the only place that said they could and would do it! Reasonably Priced and Great Customer Service! Will definitely be back if ever in the area.

    I 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!

    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!

    This 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!

  • Came 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!

    Eric 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

    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!

  • 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!

    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!!!

    This 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.

    I 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.

    Got me in the same day and kept me up to date. Fixed what was needed and did not push any costly add ons like other places do. Feel like I can trust these guys.

    I 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.

Signs Your GMC Needs Air Conditioning Repair or Replacement

Use the following signs to help determine if your GMC needs air conditioning repair service.

  1. 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.
  2. 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.
  3. 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.
  4. Air conditioner emits a strange odor. The air coming from your GMC 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.

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.
