"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."
