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 Dunwoody area has never been easier, thanks to McCullough NAPA Auto Care.

My 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.

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!

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!

I 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.

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++++++

Eric 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.

Honest and fair price!!! I went in for 60k mile service. They said I only needed oil and cabin air filter changed. That is refreshing honesty! Saved me big bucks! This will be my new shop for my car 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!!!

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!

Had experienced front tire damage hitting metal debris on I-285 just before Rosewll exit. Immediately exited on Roswell and saw NAPA sign and pulled in. Place was busy! But got attention immediately by Jeff service worker. Got tire off my car no waiting. Wow! Determined rim bent but tire still good. He could have sold me a new tire and i would have not known better. So appreciative. Then met with Eric McCullough and quickly arranged to have rim fixed. I decided on new tires for safety and were worn. Eric got me great deal on tires and had my car fixed SAME day. Eric runs a super customer-focused operation. Kudos! Bruce Fike

This place is a life saver. Great communication, great service, and very professional people. Eric worked with me through my whole repair.

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

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!

I 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.

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.

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

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.
