"This is a well run company! The service is seriously second to none. They were the only team that would hook my best up to my whole home humidifier. They are clean, friendly, open to feedback and a truly progressive and HONEST company. Seriously just try them once and they will be your new go to HVAC team. I have referred 4 people so far and they have all had similar experiences!"

"We had a great experience with Harmonic. First, a fair quote was furnished within a day and we scheduled the job to be completed shortly after. The team arrived on time and ready to work. Each person knew their role and was knowledgeable, so the job moved along quickly. The completed work was top notch. They took time to answer all my questions and explained how to work the new system. Our home air feels great now and we are happy with our decision to go with Harmonic."
