"Shawn serviced our furnace. He explained everything he was doing and showed me the areas of concern. He was able to figure out the problem and cleaned the areas that needed it. He was honest and knowledgeable. Great service! Thanks! "

Furnace Repair

R . M from Aurora, IL

"Harmonic has been providing us with preventative maintenance on our heating & air conditioning system as well as our water heater. Always professional and trustworthy. They helped nurse our systems until they were no longer reliable and we felt confident in giving them our business when replacing all 3 units. "

Rock Star Maintenance Program

H . M from Naperville, IL

"Service was great. They were able to come and install the AC unit within a week of when I first called them. The technician was friendly and respectful of my house and pet. The unit was installed within three hours of their arrival and operates as expected. Highly recommended."
