I have been with Cool Masters Servicing since the inception with Jonathan. Since his retirement, the transition to new ownership has been seamless.My recent technician, Eduardo, was fantastic! He has the best personality to be in customer service. He was very thorough inspecting the two very expensive HVAC Carrier systems I had installed a couple years ago.Eduardo showed me how to work my fancy thermostats, including programming the zoning I had done. He also showed me how to clean the filter in my basement dehumidifier.I am extremely happy with Cool Masters and highly recommend them.

I have to tell the world what a pleasure it has been to do business with this company. I had to have my HVAC system replaced in my home after purchasing my home 5 years earlier. The companies that I had out to attempt to repair my unit were a true nightmare until finding Cool Masters. They came in an educated me on HVAC systems and what my most affordable choices were. Never pressured me or even try to sell me additional add on. I had been without a HVAC for a month and they set up installation right away. It was amazing how they removed the old unit and repaired and added duct work. They cleaned up everything before leaving and I absolutely love my new system. They even found affordable financing with no interest for 3 years! They have come out for maintenance since installation and came right over in the dead of the hot summer to help me with my Ecobee thermostat! So honest and trustworthy! I feel like they are family!
Response from the owner: Thank you, Suzanne, for sharing your wonderful experience with us! We're delighted to have been able to assist you with your HVAC needs and provide you with a system you love. It's great to hear you found our team honest and trustworthy—your satisfaction means the world to us!
