"When I had my furnace maintenance it was discovered that I needed a new one. Decided to replace other things that were nearing the end of their service life too. Harmonic installed a new furnace, hot water heater and a/c in one day. The technicians arrived early and got to work removing the old and putting in the new. They did a great job every step of the way. Answered any questions I had and patiently taught me how to use the digital thermostat. Furnace is working great and got it in just in time. Hot water heater has a protective pan to guard against damage if a leak ever occurred and that is a great feature since I live on the 2nd floor. If you are in the market for any kind of service this company offers, I would recommend them. They were a referral from my neighbor and I have been very happy with the yearly maintenance I've had up till now and also with the installation of my new furnace, hot water heater and a/c I will use in the Spring. There are many companies out there all competing for business. This is the one you should choose."

"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! "
