Harmonic Heating & Air Conditioning/files//harmonic-logo-footer.png$10S187 Schoger Dr Suite #54, Naperville IL 630-999-9008"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."

They are friendly and listen to all your needs, just fantastic service from start to finish. This was the second time we used them to install and maintain a HVAC system. The 1st time was at our previous residence, so when we found out our new home needed a new HVAC System we knew we would be calling them. Give them a try you will be happy you did!"

Harmonic Heating & Air Conditioning/files//harmonic-logo-footer.png$10S187 Schoger Dr Suite #54, Naperville IL 630-999-9008"Excellent install, service, and followup. Price point was a great value. I would say they are honest, fair, and a company I will do business with again. Lots of shady HVAC companies in our area. Harmonic is high quality, cutting edge technolgy, and a great value. Our new HVAC system has greatly improved the quality of clean air, AC/heat in our house. I highly recommend."
