Services
First and foremost, we are an air conditioning and heating company. Cool Masters aims to provide customers with honest and dependable HVAC service at the highest ethical standards. Located in Lawrenceville, we proudly serve all of Metro Atlanta. To ensure your air conditioning and heating systems are always running at peak efficiency, it's crucial to have an expert perform routine maintenance and repairs.
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.

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

Cool Masters Saves the Day! In the midst of an Atlanta heat wave, our old AC unit went kaput. The good folks at CM worked magic and scheduled
an appointment with a tech within a day of our calling. The tech quickly identified the issue, had the right parts on the truck, and completed the repair in good time. Because we have a service contract with them (which I highly recommend) we got a discounted price. And now, less than 24 hours later, our house is livable once more. Thanks, Cool Masters and thank you technician Raul Flores!

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

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.

AC stopped working on one of the hottest days last week and cool masters pretty much showed up within a few hours and fixed the AC in about 15 minutes. We were happy as can be. Would recommend to anyone in the area.

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.

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!
