Reviews of local pros in Duluth, Georgia

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!

Charles Kim at Kim's HVAC Services LLC is the person YOU NEED in your life... FULL STOP. As adults, we all figure out at our own pace, the people we need to have as a part of a TEAM of friends, colleagues, and professionals to make our lives easier, right ?? We all need to have a short list of (1) a trusted family physician (to keep us healthy), (2) a trusted auto mechanic (to keep our vehicles running), and (3) a trusted HVAC tech (to keep us cool in summer and warm in winter). Charles not only talked the talk but backed it up with actually getting my HVAC repaired at a reasonable price. Charles was at all times a true PROFESSIONAL, efficient, and competent while also being very personable. As an owner of a small business and an owner/operator of an HVAC company, Charles is the person you need to call for your HVAC needs because he truly cares about doing a great job because his reputation depends on it.

Charles professionally communicated through the whole process of replacing our HVAC system. His price and his service are second to none. I will not hesitate to call him again. Heat and air conditioning are not what you want to worry about. Call Kim HVAC, talk to Charles, and you will be taken care of!! 5 Stars all day long.

Charles came out next day to address the issues I was having with my hvac set up. He took pictures and explained everything that was going on. His team came out less than 48 hours later to install a brand new unit and did it efficiently along with cleaning everything up after the fact. Would high recommend his services!

Charles was a referral from a trusted friend and I’m so thankful for the recommendation! Scheduling was easy and he went above and beyond to ensure that our new system was installed and working properly. He also saved us significantly on the system and installation cost of our new HVAC system. I highly recommend him for any of your HVAC needs!

I had a great experience with this technician. After calling a number of HVAC companies with no luck, he was the only one who took the time to help me understand what I needed to check for a possible warranty claim. He was friendly, straightforward, and helpful.

In the end, my warranty had expired, so I didn’t end up needing the repair, but I really appreciated his honesty and willingness to help. I’d definitely reach out to him again for future HVAC work.

I had an unexpected outflow drain blockage caused by the cold weather and distal freezing. I was hesitant to call an HVAC service late on a Sunday, but Mr. Kim was able to accommodate us without any issue. He arrived promptly, quickly identified the problem, and came up with an effective solution despite the challenging weather conditions affecting the drainage area. We were impressed with both the quality of his work and the fair pricing. We now plan to subscribe to his maintenance services to help prevent future HVAC problems
