Auto AC Repair

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

  1. 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.
  2. 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.
  3. 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.
  4. 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.

  • 5 star review  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!

    5 star review  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!

    5 star review  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!

  • 5 star review  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

    5 star review  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.

    5 star review  I had a check engine light on Saturday afternoon, ended up being an engine coil pack needing to be replaced. It was obviously super busy and I knew I would need to leave it until Monday to get looked at. Staff was very informative and communication was excellent. Got it looked at Monday and ordered necessary part to come in the next day. Went ahead and did the spark plugs as well since I was nearing 60k miles. Picked it up after lunch with no issues. Seems like they do really well with the small space provided and very busy area right off 285

  • 5 star review  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++++++

    5 star review  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.

    5 star review  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.

    5 star review  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!
