"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. "
