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.

Always amazing, fair and very honest.

April 22, 2025Just wanted to take a moment and acknowledge the wonderful people at this company. They’ve helped me out a number of times with quick repairs, honest work, and fair prices. They are good people and the shoot you straight every time. They make sure you understand why they are doing what they are doing and exactly what to expect. Someone give Harrison a raise. I’ve called him a number of times and he’s never failed. I’ll be a customer for years to come.

Just completed my first service with McCullough, and I am impressed. I have a CPO 2013 Lexus ES 350 which I have always taken to the dealership for service for the past 8 years. At 150K, I thought it was time to explore less expensive options and more convenient. I interacted with Harrison, who is a true professional and easy to communicate with. Rather than "just do the recommended service", he suggested an oil change and complimentary inspection and then determine what, if any, additional work might need to be done. There was a relatively small amount of additional work which made sense given the age and stage of my vehicle. Pricing was discussed up front and was fair. I live close so after dropping my car off, he and Daniel came to pick me up when the works was done. In this day and age of, as Clark Howard says, "non customer service", I have found McCullough to be the exception that proves Clark's rule. We will be doing more business with them and highly recommend. Adding this after another visit to McCullough NAPA in January 2025: This is my second experience with McCullough and this was just as good as the first one. Brought in my wife's car for an oil change and overall evaluation. Harrison advised we did not need on oil change...how about that, a car place advising what's in the best interest of the customer and not an opportunity to charge for another service. Harrison and team checked out the car and advised us on the vehicle, which will go a long way to our determining if we keep or trade in. The charge was fair and reasonable. We'll be back soon for a service on our other car. Keep up the good work McCullough! Went in for a third experience and Harrison was professional and helpful as always. He pointed out some items to be on the lookout for not pressuring for immediate action. Good to have a heads up for what might be coming down the road. Will back on 6 months, or mileage, for another oil change and tire rotation and overall "health" check.

March 26, 2025My 2012 Genesis needed a new battery, so I looked at various sources and found McCullough NAPA Auto Care reviews to be reassuring and helpful. I am very glad I went there. The lot is crammed with cars to be worked on or awaiting pickup after being serviced, but the gentleman directed me to park near the service doors after I explained my need. He immediately escorted me inside, I completed a work order, and he showed me to the waiting area. I'd say the work took maybe 30 minutes, and the service agent with whom I'd spoken on the phone about a battery, called me to the desk and handed me the keys, thanking me for coming in and directed me to my car waiting in front of the service area. Everyone was very professional, friendly, and careful to explain problems found in customer vehicles, as I overheard with several people who had come in while I was waiting. I would say, aside from friendly, honesty was my strongest impression of this family run business, and I will be back!

March 23, 2025This was our first repair at McCullough NAPA Auto Repair. They came highly recommended by several neighbors on the Nextdoor app. We had an excellent experience and the price was very competitive. For example, our oil change is usually around $90. and it was around $75. Eric, the owner, called with a quote for the repairs and found an issue with the oil that could have damaged the engine. I was grateful for that and decided to let them do their multi-point inspection. They found a few small issues none of which were super expensive. Then Eric, the owner, called at every milestone of the repair. He was approachable yet professional and to the point. I was always informed on the progress of their work and the car was ready quickly. I would recommend

February 23, 2025I’ve come here twice before and was happy with the work. But when picking my car up on the third visit I learned that my bill was more than double the price that was initially quoted to me (+$2,800 instead of $1,300), which was a substantial difference for me. The shock of learning this when pulling out my wallet to pay at the front-desk was very embarrassing to say the least! They did a good job, but my advice if you bring your vehicle here is to make sure to learn more about your quoted price. In my case, when I asked the cost, I was quoted roughly $1,300 but apparently, as my bill would show, I was only quoted the cost of “parts”. If this distinction was make known to me then I would have made an informed decision based on the price of “labor” as well.

Signs Your GMC Needs Air Conditioning Repair or Replacement
Use the following signs to help determine if your GMC 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 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 Does My Car’s AC Stop Working When I Accelerate
If your car’s AC stops working when you accelerate, you’re not alone. Many drivers experience this issue where the air conditioning functions properly at idle or low speeds but suddenly weakens or shuts off when pressing the gas.
Understanding why your car’s AC stops working when accelerating can help prevent bigger problems down the road. Several potential causes may affect your AC’s performance, from low refrigerant levels to electrical or mechanical malfunctions. Let’s review the most common reasons and how to fix them.
Why Does My Car AC System Rattle and Make Noise?
Is your car’s air conditioner rattling or making noise, leaving you worried about a potentially expensive repair in the near future? You’re right to be concerned—an AC system that rattles is often a sign that something might be wrong with your car’s a/c system. While a rattling noise can sometimes indicate a minor issue, diagnosing the source promptly is important to prevent further damage.
Why Does My Car’s AC Smell Bad?
It’s a common and unpleasant experience: you turn on your car’s air conditioning on a hot day, and you’re hit with a bad smell instead of a refreshing breeze. A car’s air conditioning system is crucial to a pleasurable driving experience, especially during the hot summers in Atlanta. It keeps the interior cool and comfortable, making long drives and daily commutes bearable. However, foul smells coming from the AC can quickly turn a pleasant drive into an unpleasant one.
Beat the Heat: How to Ensure Your Car’s AC is Ready for Summer
The summers in Atlanta, Georgia, are notoriously hot. Every car owner must pay attention to the air conditioning system in their car to keep cool in these warmer months. When the sun’s rays intensify, the comfort of a fresh and well-regulated car interior becomes a sought-after sanctuary. Therefore, an essential element of your summer preparations should include ensuring the air conditioning system in your car performs at its optimal best, providing much-needed relief from the summer heat.
Why Recharging Your Car’s AC is Not a Do-It-Yourself Job
During a sweltering summer, a well-functioning AC system is your car’s best friend. However, the effectiveness of your car’s AC system might diminish over time and require a recharge. While you may be tempted to take this on as a DIY project, this article aims to help you understand the benefits of a professional car AC recharge service.
The Benefits of Regular Auto Air Conditioning Service
Regular auto air conditioning service ensures a smooth-running and comfortable vehicle. In particular, a preventative maintenance plan holds the key to the longevity and optimal performance of your car’s AC system. McCullough NAPA Auto Care offers 30K, 60K, and 90K mile maintenance plans to ensure your vehicle gets the timely and steady maintenance it deserves.
