R.J. O'Neil Inc. Mechanical Contractors

I have been using Harmonic for a while now, mostly for HVAC service. My annual A/C maintanence was scheduled and Keith arrived on time and in a courteous manner. He advised me of his findings and suggestions. I felt he was very knowledgeable and answered all my questions. This is the type of service I have received from everyone at Harmonic each time. I recommend them.

This is our first time working with Harmonic heating and air conditioning. We found them on google when you search up (furnace replacement) Our current furnace is 15 years old and stopped working and was time for a new one. They provided 5 star service from the beginning from the sales representative (Daniel) who helped set up the appointment to the handyman HVAC technicians Brandon and Cris who are professionals at their job they showed up on time they placed drapes/tarps to prevent damage to the carpet and before I knew it they were done and my house was warm and cozy. Harmonic will be our yearly maintenance guys.

Harmonic delivers time and time again. They are courteous and responsive. The folks on the phone are understanding and quick to assist. I have had Daniel as my tech a couple of times, and he is an outstanding, Knowledgeable professional who provides a wealth of information where I learn something in the process. I had lost my heat during this Recent cold snap and Harmonic dispatched tech quickly, Daniel Arrived on time assessed the situation quickly, and got the heat up and running in short order. terrific service. I highly recommend Harmonic great team of great people to do business with. Five stars
