Customer Testimonials


I have been a customer of MM Comfort Systems for over 18 years and have always been happy with their service. Recently they replaced my 20 year old furnace. First, I would like to recognize Derrick in Sales. He is very knowledgeable and reviewed different options and answered all of my questions. His communication with me was excellent throughout the project. I selected a new Carrier furnace, a 5-stage A/C unit and a smart thermostat. The installation was professional and completed in one day. I had some follow up questions about the T-stat programming. Their technical representative, Tor, met with me, modified the system programming and answered my questions. The new system is very quiet and exceeds my expectations. I highly recommend MM Comfort Systems.
