Cool Masters Services serviced my heating & cooling unit and reported significant leakage in the 67 year old unit. No other vendor noticed this despite years of service. For this, I'm truly grateful it finally got noticed and properly repaired. I couldn't be more pleased with the finished product. No more leaks and my system is completely refurbished. Thank you, the team who completed this work. Thank you, Humberto for identifying and reporting the leakage! Thank you, Ian and Chris for supporting all the repair work that was needed. Despite challanges, you kept focused and knocked out the work very professionaly. A huge thanks and relief at my end knowing the refurbished work is to spec and upgraded.
Response from the owner:Thank you, Mysterymoveswashout, for your wonderful feedback! We're so glad Humberto, Ian, and Chris could help you with your heating and cooling unit, and it's fantastic to hear you're pleased with the refurbished work. Your satisfaction means a lot to us!

Apparently, I needed a new HVAC system after shivering in the nine-degree weather at Christmas. Eric came out to do the estimate. He arrived on time (even a couple of minutes early, which says a lot to me). After checking out the system, he explained everything to me and answered all of my questions. The system was installed, and they've checked on it several times. Gabriel and Joey are two of the wonderful young men they have working for them. Everyone has been super polite, friendly, and professional. If you need a new HVAC system, repairs, or maintenance, you won't be sorry if you choose them!
I've had my new HVAC system for a couple of years now. The guys come out twice a year for maintenance. Today, 3/11/25, Eduardo came out. He did an excellent job. He was polite and courteous.

Gas hot water heater replacement. Competitive price and the job was quickly scheduled after the estimate. Upon arrival , the Service Technician suggested we relocate the water heater in our mechanical room to free up space- no additional charge. Good job cleaning up afterwards.

Discovered upstairs AC not working on the first hot day of the spring last Saturday. Called several places who said they could schedule a call next week.
Called Cool Masters around 11 AM, and dispatcher said they could set me up for 2-5 PM that day. Jonathon called and arrived at 3 PM. He found a tripped breaker, and that the most likely problem was the compressor. But when he checked, he found no problem with the compressor itself, but that a seldom used heating component that prevents ice from forming when AC is running in cooler outside temperatures was the problem. He disabled the faulty, but unnecessary part, and immediately problem was solved. He checked the Freon level, found it was down slightly, and topped it. off.
Jonathon is by far the most professional and the sharpest technician I have ever dealt with for any home repair. He noted that the unit was 21 years old, and provided current estimates for replacement when it inevitably dies. His advice for the time being was to "run it 'til the wheels fall off". When that day comes, I will be calling Cool Masters, and asking for Jonathon.
