Harmonic Heating & Air Conditioning Repair & Replacement

Working with Harmonic for our new furnace and ac package was great from start to finish. From the estimate and sales to the installation and paying for the work, Harmonic was professional and communicated very well. I would recommend Harmonic to anyone needing heating and air conditioning work in the Chicago land area. They are top notch!

Have been a customer of Harmonic for several years now. We have had them service our furnace as well as install new Central Air. Our unit never worked so well until they applied their magic. They have very knowledgeable people that can explain things about the service they perform. Our Thanks to Harmonic! They're the Best!

Nate from Harmonic serviced my furnace right before the big January deep freeze. He even returned the next day with the right filter I needed for my furnace to run properly. Excellent customer service skills from everyone at the company, including Liz who booked the appointment.

I love the "Rock*Star Maintenance Plan". It saves a ton of cash and provides priority service. Don't worry about your furnace or air conditioner ever again. They take care of everything! Love Harmonic!

Probably one of the most knowledgeable and ethical companies I know. When it comes to what is right for your home and the latest and most efficient technology which saves you money in the long run, you cannot do any better. Great people to do business with.

A well-earned five stars! Kenny's knowledge was eclipsed only by his friendly personality. I would definitely call them again!

Love Harmonic! They are very professional and have great customer service.
