"Thanks Andy. We love what we do. Always glad to help with some of the most important systems in a family's home. The heating and air conditioning as well as the hot water heater are the key components to keeping us COMFORTABLE through the year. We always joke that our job is to keep people COOL in the summer, and WARM in the winter. We hate cold showers too. So we're glad to meet your expectations. Remember to protect your equipment with one of our 3 Rock*Star Furnace & AC Maintenance Plans to keep your HVAC equipment healthy all year. "

"Thanks Guy. The entire industry is experiencing an unprecedented price increase across the board on materials and cost of goods. So all of our expenses have increased significantly. Some expenses are up 20%, from gas in the trucks to the metal, repair parts, refrigerant, pvc, so on and so on. We hope to see prices stabilize soon, but until then, we're trying to help our customers SAVE as much money as possible on their HVAC service, repairs, maintenance, and even Furnace or AC replacement.

"I had two new Air Conditioners installed by Harmonic recently and am very pleased with every aspect of the process. What is outstanding is the responsiveness, attention to detail and professionalism of every individual I interacted with at Harmonic. They were great at explaining and answering any questions I had. The scheduling was easy, the technicians arrived promptly, they completed the work and went over what they did, left the places clean. Shoutout to Liz who has been fantastic throughout the process! Highly recommend Harmonic to anyone, I know I will continue to use them."
