Jeremy at Harmonic

As a kid Jeremy never imagined being an HVAC technician or running an HVAC company. But he did love science, problem solving and working with his hands. He's now one of the most respected business owners in the region, and a leader in the service industry.

After graduating high school in Oswego, while working at an auto body shop, he kept hearing ads on the radio for an HVAC tech school. Something about them appealed to him so he enrolled in the Wabaunsee Community College HVAC program.

From the start Jeremy loved the troubleshooting process of repair. But what excited him even more was the scientific approach to HVAC. Especially newer advances revolving around green energy, “smart homes” and air quality. He’d found his calling.

Now years later, Jeremy still loves the instant satisfaction of fixing things. He likes coming into someone’s home with a problem and before he leaves, he’s fixed the issue and everyone is happy.

Jeremy lives in Oswego with his wife Carolyn and their young growing family. Since Carolyn suffers from some pretty bad allergies, he loves to use her as a Guinea Pig for testing new air quality products.


Liz at Harmonic

Liz has been outstanding in her role as a Receptionist and Job Scheduler. However, due to our growth, she has been promoted to Office Manager and Administrative / Executive Assistant.

Liz is the mother of 2 young adults now, but she was an office manager for 13 years and in sales for 7 years before joining the Harmonic team. Liz grew up in Illinois and loves the area, but most of all, she loves interacting with Harmonic customers.

Liz's main goal is to make everyone happy and comfortable!


Kenny at Harmonic

Kenny joined the Harmonic team after a long career in motorsports and decades of managing various customer service related businesses. He has extensive experience in managing teams, and enjoys the challenges of business development.

Acting as our Director of Marketing, and Asst General Manager, Kenny manages all of our marketing, promotions, and advertising, as well as managing our equipment logistics, inventory, warehouse, and fleet. He's the one posting all of those photos on social media./p>

Kenny grew up on the east coast, and moved to Aurora in 2000, where he still lives with his wife and 2 daughters.


Brandon at Harmonic

Brandon graduated from Wabaunsee Community College where he studied HVAC.

He takes a lot of pride in his work and his ability to fix things. His mechanical skills extend beyond HVAC to anything around the house. He’s remodeled kitchens, bathrooms and laid hardwood flooring while working with his Dad.

He loves working with the guys at Harmonic because they are willing to share ideas and experiences to improve his skills.

Brandon is a humble guy who loves making customers happy.

Donnie grew up on a farm in Victoria Illinois, so he was always interested in working with his hands. He moved to the Chicagoland area in 2008 and went to the College of Dupage to study HVAC, finishing school just before the COVID shutdown. He enjoys playing video games and taking his dog for walks.
