" 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. :( "

" Nate was friendly and very thorough . He took the time to explain to me and my son how the furnace functions. We discussed preventative maintenance to extend the life of the furnace. My family highly recommends Harmonic."
