" Nate was friendly and very thorough . He took the time to explain to me and my son how the furnace functions. We discussed preventative maintenance to extend the life of the furnace. My family highly recommends Harmonic."

"Great. I’ve used Harmonic for emergency A/C repair, seasonal tuneups, and humidifier repairs. In my experience, they lead the way in professionalism and expertise. I also like they maintain a smaller crew."

"Harmonic technician resolved our hvac problem, we were pleased with his effort and explanation of the issue. Since it is almost fall we will not be using AC for the entire season but it worked great during these last hot days/week. We will be keeping Harmonic on our list for our future needs."

" Fantastic. Perhaps one area of improvement could be disclosing more about the service. I responded to the winter tune up special. However, I have a boiler instead of a furnace and was not made aware of the extra cost upfront. Not a problem, just something to keep in mind. All went very well."
