"Tony did a thorough job. He identified the problem and fixed it right away. He also gave some maintenance advice. Aside from doing a good job, he was also very friendly! I like that the invoice is delivered electronically and describes the work done. I would use harmonic again as well as recommend them to others. "

"Outstanding customer service. The "Rockstar Maintenance Program" is incredible. Advanced knowledge of wi-fi smart thermostats, variable speed motors, and the best equipment available to help save on monthly utilities and qualify for ComEd & Nicor rebates in residential and commercial applications. Best HVAC biz in the region by far."

"The knowledge of each of the gentlemen was well above average. They were professional. And worked us in, and worked hard for us so we wouldn't be in the heat too long. We will always be returning customers and sharing our experience with all those looking for these services. "

"Our furnace stopped working and we got a fast response with an appointment on the same day. We ended up having a dead bird stuck! It got cleaned out and working again. Quick affordable and super great service. Not long after Harmonic also took care of our family member that AC didn't work and they were happy with the service as well. "

"With the cooling season upon us we wanted to get our A/C system running in full force for the hot days coming. Thanks to the team at Harmonic our system is already working again! Thanks again!"
