Very professional, great communication and excellent service and value
Ryan Grauer
We had an old, inadequate AC system replaced and, from the initial meeting with Derek in early fall 2025 to installation in late fall to Ramses’ visit to start up the system this spring, now that the weather is warming up, everyone has been incredibly helpful and professional. The system installed works perfectly. Highly recommended.

I’ve been with King since they bought Chicagoland Heating and Air Conditioning. The service has been excellent with their punctuality and professionalism. Would highly recommend this company.My technician(Cole) is very knowledgeable and through. He takes his time with his inspection and explains everything. I always feel that after he leaves there will be no problems with my furnace.

Joe Ann Hunter
King is always there when I need them. I called around eight-ish. They were here in less than an hour. They fix my problem. It wasn’t a lot of money and they are the best thing in my life owning a home even though I have other insurance I call King.
Nicole Mallett
Prompt service! Great communication with representatives. Patient with explaining my options for buying a furnace and central air unit.I didn’t feel pressured to buy a furnace that was more than was needed for my home. Also provided me with a little hand holding when I needed support in deciding how to pay for the new furnace. Installation of the new furnace was fast and the installation steam was prompt, respectful of my home and my family.
