Living in Georgia, you know the importance of a working, efficient air conditioner. Cool Masters, Inc. takes pride in being your comfort and efficiency specialists. Located in Lawrenceville, we provide reliable AC repair and installation services throughout the area including Suwanee, Gwinnett, and Metro Atlanta.
Cool Masters services and repairs all types of heating, ventilation, and air conditioning (HVAC) systems. Our experienced, knowledgeable technicians provide superior service in a timely manner. When it's time for you to choose a new heating system, we can perform load calculations to determine the size, make, and model that's best suited to your needs.
Even though Georgia is located in the South, we still receive our share of cold weather. Over the past few winters, Georgia residents have seen snow, ice, and brutally cold temperatures. It's times like these when we really appreciate the luxury of a heat pump. However, there comes a time when these machines break and require repairs to escape the frigid weather.
Imagine coming home after a long day of work only to find your home flooded. Despite the advances in technology, all water heaters will eventually break and require repairs. Regular maintenance certainly helps, however, these machines can still break over time. There are two types of water heaters.

Chris, my technician, is the best. He kept me updated on his arrival time. He worked efficiently while he was here, showed me anything that would be for future maintenance consideration, and even checked a system that wasn't due for service yet. Jonathan and the whole team are the best.

Very professional and thorough. Did a great job on explaining what he was doing and what maintenance I will need. Chris was also helpful and honest on what parts of my AC unit were worth replacing before needing a whole new one

Had to replace attic fan motor and Jonathan was great with the evaluation, estimate and working with our home warranty.
Mike was outstanding, performing the installation quickly and quietly, while we worked from home below.
Would definitely hire Cool Masters again.

Had an issue where my AC would not cut on. I tried every DIY trick in the book, finally decided to break down and give these guys a call. I'm glad I did! Mike came out and was EXTREMELY professional, friendly and more importantly really cared about the situation. I never write reviews, but I had to with Cool Masters. On time, honest price and Mike a great tech. Would highly recommend you give them a try

This team is the real deal all around. I'm next door neighbors with the owners of the company. Down to earth people. They are professional and so personable. They do what they say they're going to do. We found mold in our home about a month ago. The team went right to work doing what they do best. I'm so thankful we went with Cool Masters. They have such a good report in the community...I can see why!

Got a humidifier put in on recommendation from Jonathan. It did not work for even one day. It started leaking water in the tray under the furnace unit and blew the pump out. Jonathan comeback and made me pay for the pump and replacing it. He told me that the humidifier had issues and needed to be replaced by the company. Come next year when I needed the humidifier, he tried to upsell me to something else. DO NOT USE THESE GUYS...they will not stand behind their work. I can post pictures of the big paper weight attached to my HVAC/Furnace unit and you can PM me to confirm that this is true. I think

Our AC stopped working. We had one of the larger HVAC companies come check it out. The technician said the unit was beyond repair and we'd spend as much fixing it as we would replacing it. He then scheduled his sales guy the come out the following night and walk us through our options. Replacement sounded like the only option. I called Cool Masters to give me a quote on replacing it so I could get multiple quotes. The service manager came out thinking he was pricing a full replacement. He did his own investigation and found that the unit was only 7 years old (we purchased the house

Not having a/c in the middle of the summer is brutal. Cool Masters came out right away and the issue was fixed within 30 minutes. What a relief! We've used them before and were pleased. They're our new "go to" a/c company.

We got the dip and twirl from one of the big corporate companies and Jonathan came out and was honest about all of our needed repairs. Hands down the best customer service I've received from an HVAC provider. He even came out the next day and stayed until 8pm perfecting everything. Will recommend and use them for my future HVAC needs.

Cool Masters if nothing else was very polite -- after I called to inquire about where the technician was, nearing the end of my originally scheduled 3-hour window. I do understand that things come up and estimated times can shift. However, I waited for three hours, only to call and find out my appointment had been moved without properly notifying me. I hate to leave a critical review when no service was performed, but I just can't let it slide that I wasted three hours of a busy workday to accommodate a no-show/changed appointment that I wasn't explicitly made aware of ahead of time.

We have have called on cool masters several times for both heating and air conditions issues. All of the servicemen we have encountered have been friendly, knowledgeable, and helpful. They have a personable touch and build report quickly. You feel like you can trust them in an industry where it is hard to find trustworthy repairs. They have fixed the problems/issues to our satisfaction each time. Highly recommend the Cool Masters team.

Excellent service!!! The best experience with a company in this arena by far!!! Placed a call for AC repair ( of course before a holiday weekend), the representative was empathetic and knowledgeable - she took the time to explain the whole process and scheduled a specialist to come to our home promptly. Enoch was a blessing!!! He quickly diagnosed the problem and offered solutions. Cold air was flowing from our vents in no time. We feel confident in the decision to have Cool Masters involved with this home repair!!!

Update : 6/17 Had an AC issue and I knew I could count on cool masters. Enoch came over, was a pro, explained everything, and resolved the issue. Very fair and put the customer first. Thanks guys!




100% best organization I have ever worked with as a home owner. White glove service, honest, fair, great people, and great work. The only folks I will call.

Christopher and Jesus came out yesterday and I was back up and running.

Wow very impressive my contact was with Jonathan... excellent!! Very knowledgeable didn't mind me asking questions looking over him to see what he was doing... as he explained... this guy/company went way above my expectations... I didn't feel like I was getting ripped off.. actually the price for the quality of service was much much less than I thought... I knew before I called I needed a new furnace... because of this experience they will be doing the job

Thank You Jonathan! Our house was getting up to 80 degrees before it was even 80 degrees outside! He took the time to listen to the problem and came out and fixed it quickly. He even made some suggestions on things we could do ourselves to make out HVAC run more efficiently. I also signed up for a service plan with them because they are the best!

Cool Masters has been servicing our two homes for the past few years. Jonathon and his technicians are outstanding! They are the only company that will answer a emergency call regardless of the time! They take the time to explain what the problem is and provide the best possible solution. And they never try to push any additional services! I truly appreciate their honesty and will continue to use them. Thanks again!

I'm pleased with the work done at the house. It was a cold week and my 12 yr old furnace. I wasn't home when Jonathan came to service it but my boyfriend was there. He explained to my bf the reason why the furnace was broken, showed the motor, explained the life of the motor (about 10 years). He also didn't mind explaining it to me for a second time over the phone. I will do business with them again.

Great Big Thank You to Coolmasters! Our furnace went out at 1:30 AM and I called to leave a message but Coolmasters ANSWERED! Five minutes later I had an appointment for 7 am...5.5 hours later! Tech was there on the dot and finished 35 minutes later. So glad we use Coolmasters for our maintenance too because we saved a lot today. I didn't think companies like this existed anymore!

Used them twice. First time, guy who worked on our air conditioner was not that knowledgeable. Second time was totally opposite experience. Not sure what to think. Will try to use them again. Pros ...easy to schedule appointment, good communication, right on time, good price.

These guys were life savers, I live in NJ and needed emergency work on a job that was poorly done at my sick mothers house in Norcross. It was done completely wrong by a contractor we later learned was an unlicensed contractor who basically robbed our family out of the money (6k) and never finished the job. My mother lives alone and recovering from a cerebral stroke last November. With a few cold days in late October I was in a state of panic. I started looking for someone reputable who would be honest and save us from the disaster that was done at my mom's house. I needed a quick turnaround
