"The harmonic team once again displayed skill, professionalism, and enthusiasm for helping others with their HAV home needs! I bought a brand new Furnance/Thermostat system from Harmonic. From order to installation was seamless! I am literally thankful for the blessing of knowing that whenever I have a HAV need, my solution is one phone call away! The furnace system is very quiet and digital apps help me to control it from anywhere my digital tools and I are at in the country! So if you are looking to have new system to be installed or a HAV problem to be solved, I encourage you to call Harmonic! They truly are a blessing!"

"Everything about this sometimes difficult change-over to a new furnace was professional. Jeremy explained the options and his opinion on what would do the job. Harmonic agreed to perform the work right after the holidays. Nate & Brandon showed up on time and could not have been more courteous and efficient. They even spent time with me setting up the app to control the new Honeywell thermostat. A supervisor stopped by during installation. All equipment operated right out of the chute. Jeremy and Liz subsequently sent follow up emails making sure I was getting along with my new HVAC system. Total satisfaction!
