HVAC reviews in Duluth, Georgia

punctual, respectful and professional. highly recommend Mr. Kim. also, he fixed minor issue free of charge. i have two hvacs.

Excellent Service. So happy we found Kim's HVAC Services. Charles worked his magic on my 16 yr old AC system and she is cooling like a champ again. Charles came out to provide system maintenance and not a sales opportunity, like some other companies. Be sure to add Charles Kim to your list of good, reliable, and fair priced contractors. We highly recommended. 10 stars!

I had the pleasure of meeting Charles the owner. He was a very nice and professional person. He fixed my AC on a weekend and did not charge more. He is very knowledgeable. I would 100% use him for all my AC needs.

The services provided were great. Charles helped me out tremulously and was very real with me with the issue and fixes needed. I would 100 percent recommended.

Charles has done the fantastic work. I saw the reviews on the quality of work he does on Facebook and I am completely satisfied with his work.
I recommend anyone looking for any AC work as well as we can take his help to do kind of inspection , if other contractors does the AC work as he gives frank opinion on the work .

I couldn’t be more impressed with the work Charles Kim did on my AC unit. After struggling with inconsistent cooling and a frustrating shutdown issue, Charles came in, quickly diagnosed the problem, and got everything running like new. He was professional, knowledgeable, and clearly takes pride in his work.

What stood out most was his attention to detail — he didn’t just apply a quick fix, he made sure the system was fully checked, cleaned, and functioning at its best before he left. You can tell he truly cares about doing the job right the first time. Now my home is cool and comfortable again — all thanks to Charles!

Highly recommend his services if you want quality work and peace of mind. A true expert in HVAC!

Mr Kim did an awesome job and made sure that he stayed till all the vents showed temperature.
And the heating raised the temperature.
I would highly recommend Mr Kim for any kind of hvac job.

I had several HVAC companies come out to look at my broken AC unit, and despite telling them clearly that my goal was simply to get it working again, every one of them told me it was “impossible” and immediately pushed me toward buying a brand-new system. The quotes they gave me for replacement were extremely high and felt more like a sales pitch than a solution.

Then Charles came. Instead of trying to sell me something I wasn’t ready for, he listened, respected what I asked for, and actually fixed my AC unit to get me through the summer. On top of that, when I asked him for a quote on a new system for the future, the price he gave me was $2,000–$4,000 lower than the other four companies I spoke with.

Charles is the definition of integrity in this industry. He does honest work, explains everything clearly, and genuinely looks out for his customers’ best interests. It’s rare to find someone like him these days—professional, trustworthy, and skilled. I feel lucky to have found him, and I’ll absolutely be calling him when it’s time for a new system.

Thank you, Charles, for restoring not just my AC but also my faith that there are still honest people in this business.

I’ve been quoted by several different AC companies, I contacted Mr. Kim, Charles personally responded gave me a price which I found quite pleasant, came out to next day installed the system. The man stayed here till 11 o’clock at night installing my AC system my AC system is now throwing ice cubes. It is so nice and cold. I will definitely recommend this gentleman and do business with them again.

Charles is a trustworthy and knowledgeable expert in his field. His commitment to customer satisfaction is a cut above. Would recommend!

Charles arrived at my home within 30 minutes. He quickly assessed the situation with my HVAC system and diagnosed the issue as a faulty thermostat. I was very impressed with his excellent service, outstanding customer support, and friendly rapport.rt.

Mr. Kim is the best! Quick to respond, honest, and very reasonable pricing. Our heater was having problems and instead of replacing the whole unit which would have cost thousands, he replaced the part that was causing the issue and now it runs perfectly.

Great communication! Fast response. Reached out to Charles and he had me up and running the next business day. Appreciate his knowledge and expertise. Honest guy with good work ethic. Would highly recommend if you need a trustworthy AC guy!

Rock solid to deal with. Did everything he promised and was reliable and ontime. Very neat and clean install. Very strong customer service. Honest and fair. Very happy with Charles and would use him again 100%.

Kim's HVAC is fantastic. They do incredibly high quality work, and are not satisfied until the job is done! Thank you for coming and installing my new AC Units and doing such a great job.

Highly Recommend!
When our AC suddenly stopped working in our 22-month-old home, I was frustrated knowing that while the parts were still under warranty, the labor will not be.

Thankfully, I called Kim’s HVAC Services, and I couldn’t be happier with the experience.

Charles, the owner, personally came out to diagnose the issue. He was professional, knowledgeable, and incredibly thorough in explaining everything. He quickly found the leak and took the time to walk me through the root cause of the problem. His transparency and attention to detail gave me real peace of mind during a stressful time.

It’s rare to find service like this these days—honest, responsive, and genuinely helpful. I highly recommend Kim’s HVAC Services for anyone needing HVAC repairs or maintenance. Thank you, Charles!

Photos are of the builder's install where you can see was bent and the cause of the leak. Charles replaced the bent area of the copper and used the actual tool to bend without causing a kink in the metal.

Charles is amazing. We found him through good reviews and he surely did not disappoint. On time and very fair pricing. Did not upsell us anything and of any, he even told us where to get parts to save $$$. Great and honest person to work with.

Charles was very responsive, his schedule was flexible, and his prices were cheaper than other HVAC companies. Would 100% recommend Kim's Hvac services!

Amazing in every way!!! I needed service on my hvac. I called on a Sunday afternoon and received same day service, which was great!!! He was fast, efficient, excellent customer service and affordable!!! In fact, he charged less than half of the more reputable company. Highly recommend!!

Charles did an excellent job installing two thermostats in my home in Duluth, GA. He was punctual, friendly, and clearly very experienced. Not only did he handle the installation with ease, but he also identified and replaced some blown fuses, getting both thermostats up and running perfectly. I really appreciated his professionalism and attention to detail. Highly recommend!
