Schedule An AC Refrigerant Recharge or Repair Service

A lack of refrigerant in your AC system is of course going to result in a lack of cold air. Refrigerant is responsible for cooling down the air you feel coming from your vents. If you’re experiencing warm forced air when you turn on your air conditioning, it could be because of low refrigerant levels. An AC recharge is quick and helps to pinpoint the cause for error.

We will drain your air conditioning system of any existing coolant. Afterwards, we replenish the system with fresh refrigerant. If the system is still blowing warm air, at this point we know it’s not due to a lack of refrigerant.

We’ll also inspect your vehicle’s temperature control and pressure systems to make sure all the parts are working as they should. We can determine if any of these parts have a leak. If that is the case, the part will need to be replaced. We will then outline next steps toward getting that cold air back in your cabin. All things considered, a recharge service is fast and less costly than having to replace a component.

Signs Your Car Needs Air Conditioning Repair

Blowing hot air. A lack of refrigerant is the most common cause of warm air through your vents. Refrigerant is what cools down the air within the system. Mold or mildew built up within the system’s evaporator can additionally cause problems by preventing air from reaching the vents. These are both signs we look for when you bring your vehicle into our garage.
Blows cold are sporadically. Over time you may start to feel cold air turn warm with use. A lack of coolant can lead to a lack in performance. Another reason for poor performance may be due to a broken component within the system. Our technicians inspect the entire air conditioning unit in order to find the issue and fix it fast.
Unusual noises. Loud noises are not common with AC systems. A faulty compressor could be reason for these strange noises. The compressor is responsible for pressurizing refrigerant properly and forcing it through the vents. As time passes, a compressor undergoes wear and tear. In this case, that wear and tear may be what is causing those unusual sounds. Have your compressor inspected when you suspect a decline in performance.
Strange odor. Air coming from your AC vents should not smell bad. An old cabin air filter can lead to foul smells. Filters are easy and cheap to replace, and should be done so at least once a year. Mold and mildew may also produce foul odors that get pushed into your cabin as air blows through. Given these points, our professional technicians look for these signs upon inspection.

Our ACE-Certified Technicians can certainly determine the root cause and give your system new life. AC repair for your car in the Roswell area has never been easier, thanks to McCullough NAPA Auto Care.

A 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! I highly recommend McCullough NAPA Auto Care to you. You will not be disappointed by the care they put into your vehicle.

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!

Great 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!

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!!!

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.

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.

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

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!

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 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

Eric 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!

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.

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.

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!

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!!!
