"Fantastic. We try to provide the best VALUE for our customers. We're always trying to get the best rates on equipment so that we can pass that savings on to our customers. Add in the local REBATES from ComEd and Nicor, along with any available manufacturer rebates, and we can sometimes save customers over $1000 on their Furnace & AC purchase. We do our best to provide the best service and the best equipment at the best price. Most importantly, we're always working to help make your home Smarter, Healthier, and More Efficient. Remember to protect your equipment with our famous "Rock*Star Maintenance Plan"!"

"Glad we met your expectations John. We hope you're enjoying your new Furnace & AC equipment. You should start to see a savings on your utility bills as well. A humidifier is crucial during these Chicago winters. You'll find that the home is far more comfortable and efficient, especially paired with that new Thermostat. Enjoy the season. "

"Called for an appointment and they were able to send a technician the same day. The tech did a great job finding and fixing the issue with our furnace. He explained what he was doing the whole time and even gave recommendations on different filters we can use. Overall, professional, friendly, and prompt service. Will definitely use Harmonic again in the future."

"Great Experience. We had AC breakdown and needed a quick replacement due to the hot summer. Jeremy Hesselink, was more of a solution provide than a sales person. He not only helped identify the correct system configuration we needed but also did not upsell us Zoning which many others did. But the best part was, he made the current system usable till the scheduled installation date of the new system. The team who came the Installation were professionals. They not only did a professional install including a final walkthrough, but also cleaned up after they were done. Definitely recommending them. The house was never comfortable as it is now."
