" Fantastic. Perhaps one area of improvement could be disclosing more about the service. I responded to the winter tune up special. However, I have a boiler instead of a furnace and was not made aware of the extra cost upfront. Not a problem, just something to keep in mind. All went very well."

" I would definitely give 5 stars. Brendan (sp?) was very polite, courteous, and knowledgeable. I take comfort in the fact that I do not have to worry about the furnace especially in the cold weather because it has been well serviced. Thanks, Harmonic, for a job well done! Nancy Fey"
