"Harmonic has been providing us with preventative maintenance on our heating & air conditioning system as well as our water heater. Always professional and trustworthy. They helped nurse our systems until they were no longer reliable and we felt confident in giving them our business when replacing all 3 units. "

"That's the best execution of our Rock*Star Maintenance Plan. We have 2 plans (VIP & Total RockStar) for older HVAC systems AND hot water heaters that provide great discounts on those Doctor Visits when the equipment is toward the end of it's life, and need more maintenance or repair services. However, the General Admission is perfect for even new systems to cost-effectively clean, service, and maintain your new furnace and AC even when they are new. We're always happy to serve our community and help everyone save money on their furnace and air conditioner repair services or installation. Best feature of all 3 plans is that they provide a discount on NEW HVAC equipment when that time comes. Thanks for trusting Harmonic. Enjoy the season. "

"Had to finally replace an old furnace, from the beginning of the process and through to the installation I received nothing but courteous. friendly, and what I believe to be, an accurate assessment of the best direction to take after assessing the situation. Installers, Brandon and Donnie, arrived as scheduled, completed the job within the parameters I was told, and made sure all my questions were answered. I have depended on Harmonic for some time now and will continue to rely on them in the future."
