"This review is long overdue! We contacted Harmonic after a problem with a different HVAC company about a year ago and have been thankful for the service received from Harmonic ever since! Our most recent appointment for spring tune up with Tony reminded me how much I appreciate them. He is terrific! And a big shout out to Jeremy, Brandon and Liz who have all been wonderful to work with too! You all are the best! Thank you for providing great service."

" The guys were super nice and the heater is working great! Our only issue is I went upstairs after they left and I found grease spots on our near white carpet and other pinkish stains as well right outside of the door to the heater room. :( "
